Toola, the Southern Sea Otter

There are individual animals who have had a profound effect on humans and on animals. Toola the Southern Sea Otter is one of them.

Toola, the first sea otter ever to foster stranded pups, is one of the Mighty Dead. She persevered, in spite of her daily seizures, to pioneer the rehabilitation of sea otters back into the wild. Moreover, Toola inspired important legislation for sea otter conservation. Most importantly, she fostered thirteen stranded pups who now have successfully raised families on their own in the wild. Toola is considered, by many, to be the otter who saved the southern sea otters from extinction in the wild.

"Toola with Pup," by Randy Wilder, Monterey Bay Aquarium
Before Toola, the Monterey Bay (California) Aquarium’s Sea Otter Research and Conservation Program (Sea Otter Program) could not successfully release stranded pups to back into the wild. Raised by humans, these sea otters were too accustomed to people to survive on their own. The Sea Otter Program, which was started in 1984, was failing in its main mission. Then Toola was rescued in 2001.

Found on a beach, suffering from seizures, Toola, who was pregnant, was taken to the Aquarium. The vets determined that she was suffering from toxoplasmosis, a parasite spread by cat feces. Toola could never be returned to the wild, since she needed daily medicine to contain her seizures. Adding to her woes, Toola lost her pup.

The Aquarium was now faced with a dilemma – what to do with the grieving Toola and a weakened pup who had been stranded. They decided to see if Toola would nurse the young pup. No aquarium or sea rescue group had ever thought of having sea otters as foster mothers before. Toola took to mothering as her mission in life. She became the first of many sea otter mothers to foster pups. Toola taught the pup, now her foster son, how to dive, how to crack open clams, and how to successfully eat crabs. Her pup is now the head of a pod of otters, and the father of many pups himself. Since her arrival, the Aquarium has had a successful release rate, now they had Toola teaching them.

Toola raised awareness of the human impact on the environment for sea otters. Since her deadly toxoplasmosis could only be abated by daily doses of medicine, Toola had to remain at the Aquarium. This parasite found its way into the watershed system by the careless dumping of used cat litter. Assemblyman Dave Jones (D. Sacramento) enacted legislation to place warnings on kitty litter bags about the proper disposal. He also set up a donation box for the California Sea Otter Fund on income tax forms. More funding also was allocated to saving the southern sea otters.

Toola died of old age (about 16 years old) in March 2012. Dr. Mike Murray, the Aquarium’s veterinarian, said “I will argue that these is no other single sea otter that had a greater impact upon the sea otter species…” He joked that she ruled the Aquarium with an iron webbed fist. Dr. Murray said of her passing, “Toola did what she has always done. She went out her way on her terms. May we all be blessed to go out the same way.”

Sea Otter: Second Chances

When people think “otter”, they often imagine Sea Otter with her cute face, floating on her back, holding a clam. The most aquatic of Otters, Sea Otter spends most of her life at sea. Since She likes to be in the water near the shore, Sea Otter prefers living along coasts instead of the open ocean. During rough weather, Sea Otter will seek shelter in a rocky cove.

Unlike other Otters, Sea Otter will catch fish in her clawed forefeet. Other times, She dives to the sea bottom, snatches a tasty clam, and returns to the surface. Swimming on her back, Sea Otter uses a rock and bangs open the clam on her chest. She eats crabs, being careful not to get her nose pinched.

Sea Otter is a keystone species since She maintains the health of the near-shore ecosystem. Sea urchins which attack kelp are her favorite food. Since She maintains the kelp forest, many species have their homes there. Places where Sea Otter has been reintroduced has rebounded in health and been restored.

From time to time, Mother Sea Otter will gather with other mothers and their pups. While her pup is playing with the other pups, Mother Sea Otter grooms herself to keep her fur clean. As her pup has fun with his playmates, Mother Sea Otter rests with her friends. Usually, She has her pup rest on her stomach as they float in the estuary. The bond between mother and pup is so close, that a mother will carry and mourn a dead pup for days.

Because She lives in the cold waters of the Pacific, Sea Otter has the thickest fur of any mammal. To keep her fur in prime condition, Sea Otter will lay on her back and blow air into her under-fur. To clean Herself after eating, She will somersault and twist and turn to get the debris off her fur.

Sea Otter’s history with people is a sad one. Russians and Americans hunted Her to near extinction for her fur. What saved Sea Otter were other, more thoughtful people. When the hunters thought that there were no more sea otters, other people knew where sea otters were hiding and kept the place secret. After laws were enacted to save the sea otter, her numbers slowly recovered.

Today, sea otter populations face other problems. Coastal pollutants and habitat degradation limit the number the survival of the adult otters. Used cat litter has infiltrated the watersheds bringing with it lethal parasites. Every sea otter counts to the people of California who are doing their best to keep these mammals from going extinct.

Sea Otter once trusted people before they hunted Her. After about a hundred years, Sea Otter is willing to trust again. As people are working to give Sea Otter a second chance to thrive, so She is giving people a second chance. Learn from Sea Otter when to trust and when to walk away.

BALEEN WHALE FAMILY: Travel the World

Southern Right Whale
The largest Animals that have ever lived on earth, Baleen Whales depend on tiny organisms (Krill) for food. They strain the Krill (Norwegian for ‘whale food’) through bristly baleen plates in their mouths. Since Baleen Whales have no teeth, They swallow or gulp their food whole.

Each Baleen Whale has their own type of baleen and style of feeding. Bowhead Whale, who has the largest baleen, feeds yearlong in the Arctic. Meanwhile, Right Whale cruises with her mouth (which is full of finely fringed baleen plates) open. Swimming on his side, Gray Whale stirs up sediment in the shallow waters with his head. Using his tongue, Gray Whale pumps the sediment into his mouth, strains out the dirt, and eats his prey.

Songs of the Whales” made Baleen Whales famous in the 1970s. Unlike Toothed Whales, who communicate with clicks, Baleen Whales use vocal sounds. Forming a language, these complex songs, which can last for 15 minutes, travel long distances through the ocean depths. Blue Whale uses the lowest sound on the bass register. Fin Whale also emits bass-frequency grunts, but not as low as Blue Whale. Among the Whales, Humpback Whale sings his famous songs during mating season.

Besides their songs, Baleen Whales are also known for their long migrations. Many spend summers in the food-rich polar waters, and move to warmer waters in the winter for breeding. Baleen Whales in the Southern Hemisphere migrate from the Antarctic to New Caledonia. Meanwhile, in the Northern Hemisphere, They go from Greenland to the West Indies. As They go on their epic migrations, Baleen Whales live on the energy stored in their bodies. Although Many Baleen Whales are not sociable, as a rule, They will travel in small groups to their winter and summer grounds.

Baleen Whales are great travelers. On their annual migrations, Some Whales cover a distance almost equal to half the earth’s circumference. Long journeys do not seem to faze Them. “Come see the world,” the Baleen Whales call to you.

Families of Baleen Whales (Mysticeti):
Rorquals (Blue, Fin, Humpback, Minke, and Sei)
Right Whale
Pigmy Right Whale
Gray Whale
Bowhead Whale

Note: Baleens are thin, long, triangular plates of keratin (same material that human hair and nails are made from). These plates grow down from the Whale’s gums, covering the upper jaw.

Conservation Note: Baleen Whales are seriously endangered, and some species may not recover. They are protected by international treaties. Moreover, many countries have restrictions on whale watching to keep the whales safe during breeding seasons.

BELUGA WHALE: Friends You Can Trust

Known as “Ghost Whale”, Beluga is the only whale that is all white. Because of her pale color, Russians named Her, Belulcha, which means “white one”. Like Manatee, Beluga was once thought to be a mermaid. Today, She is a major character in children’s stories.

Like her Mother, Beluga returns to the same river estuary every year. Her Mother first took Her to their “home” when She was a Calf. However, when the ice freezes over her estuary, Beluga will leave her home for warmer coastal waters. But come the springtime, She returns with her Calf to feed in the nourishing Polar waters of their estuary.

Unlike other Whales, Beluga has a flexible neck, and can move her head from side to side. Because of her unique ability, She does a visual sweep of the ocean floor while swimming. Her famed flexibility extends to other parts of her body as well. Beluga’s bendable flippers help Her get out of tight squeezes. Her moveable face makes Her one of the most expressive whales. In fact, She often forms her mouth into an “O”. When She is unhappy, Beluga will squirt the offender with streams of water from her puckered mouth.

Since She travels in pods of a hundred or more Whales, having a social life is important to Beluga. Called “Sea Canary”, She chirps, peeps, and squeaks to her Pod Mates. In her Pod, Beluga talks with Them all, using trills, chirps, and clucks. Sometimes, She sounds like a rusty gate or an out-of-tune string band, conversing with other Belugas.

Life in Beluga’s Pod is loud and noisy. The only time, She and her Friends are silent is when Orca (Killer Whale) is near. Then silence rules the ocean waters. Beluga shows that, with friends you can trust, you will always know when danger is near.

MEDITERRANEAN MONK SEAL: Fragility of Life


Support Monk Seals in Turkey
In ancient Greece, Mediterranean Monk Seal was placed under the protection of Poseidon, the God of the Sea, and Apollo, the God of the Sun, because Monk Seal showed a great love for sea and sun. The Greek sages, Homer, Plutarch, and Aristotle, immortalized Him in their writings. As long as there have been people living around the Mediterranean, Monk Seal has been a part of their lives.

Instead of ice and snow, Mediterranean Monk Seal has sandy beaches and warm waters to live in. He is called Monk Seal because He is bald and is often alone like a Christian monk. Exceedingly shy, He prefers the company of few friends. Mediterranean Monk Seal runs contrary to modern people’s perceptions of where Seals live.

Mediterranean Monk Seal teaches the fragility of life. Once common to the sandy beaches of the Mediterranean Sea, He is now found only small islands and cliffs around rocky coasts, which are inaccessible to people. Cherish life as the people who try to save Monk Seal from extinction.

International Monk Seal Alliance


Mediterranean Monk Seal’s Teachings Include:
“We must act now. By protecting the monk seal, we protect the sea itself.”

ELEPHANT SEAL: Male Spirit

The largest of all Seals, Father Elephant Seal towers over all his Wives. What gives Elephant Seal his name is his huge size and his elephant trunk-like snout. Along with his bellowing roar, Elephant Seal attracts many Females to be his wife by inflating his snout to an immense size.

Father Elephant Seal arrives at his breeding beach a few weeks before his Wives, to establish his territory. By raising his head and chest, tilting his head back, He issues a loud bellow to intimidate other Elephant Seals. Usually that works, but when a particularly stubborn Seal wants his territory, Father Elephant Seal rams his bulky body against his Rival and bites Him. By the time his Wives arrive, Elephant Seal has his territory.

After breeding season is over, Everyone goes their separate ways. Alone, Elephant Seal will travel from continent to continent. In searching for his favorite food, Squid, He will dive as deep as 1,250 meters, and stay underwater for as long as an hour. Few Seals, let alone other Mammals, can do these feats.

Father Elephant Seal demonstrates the many aspects of the Male Spirit. He bellows and inflates his snout to impress the Ladies, and to announce what is his. His enormous size enables Father Elephant Seal to travel long distances both on the ocean’s surface and below. His dark side is his need to dominate to the point of risking his life. However, all things balance out, since Father Elephant Seal is the favorite food of Great White Shark, the Queen of the Seas.

SEAL FAMILY: Seeing With Your Mind's Eye


Seals (Phocidae) are distant cousins to Sea Lions (Otariidae), who are, in fact, closer cousins to Walruses (Odobenidae). To many people, this seems odd, since they think that Seals and Sea Lions look alike. Actually, the “trained seals” at circuses are really female California Sea Lions. Seals are more streamlined and without noticeable ears. When on land, Seals move like Caterpillars, instead of walking, like Sea Lions and Walruses.

Contrary to popular belief, Seals not only live only in the Arctic and Antarctic, but also in the warmer seas as well. Also, Seals can be found living in inland seas like the Caspian Sea and Mediterranean Seas. Ringed Seal and Baikal Seal live in freshwater lakes. Hawaiian Monk Seal can be seen sleeping on the beaches of Hawai’i.

Humans have long traditions regarding Seals. The Romans believed that sealskins would protect people from thunder and lightening. The Scots and Welsh tell of seal-people (Selkies), who would become human by laying aside their sealskins and walking on the land. Some Irish and Scottish families claim Selchies as ancestors. Other Celtic peoples regarded Seals to be messengers from the Fairy Realms.

Seals connect people with the mysterious. They live in the water yet come on land from time to time. Seals have large eyes, rounded heads, and receding chins that resemble human children. Bobbing above the surface of the ocean, Seals watch life with uncannily human eyes. They could be people if you had the imagination to see Seals as “seal-people”. Seals help people to see beyond what is and to see with their mind’s eye.

WALRUS: Hidden Talents

Although Walrus’ home is the Arctic, He is well known. Familiar to everyone, Walrus is often depicted in cartoons as a banker. With his long tusks, wrinkled skin, and mustache, He makes an unforgettable sight.
Related to Seals and Sea Lions, He shares the same Pinniped characteristics of ‘fin feet’. Walrus may have flippers for feet, but He is better known for his tusks. People in the Arctic call Him “tooth walker”. Moreover, Walrus’ scientific name Odobenidae is Greek for “one who walks with his teeth.”

Walrus spends his days resting on ice floes or swimming in open water near the shore. Where there is no ice, He hauls out (pulls himself out of the sea) on to rocky shores. Walrus enjoys sunbathing, and like many people, He gets sunburned. (His name “Walrus” comes from the Norse languages for “rust-colored whale.”)
Usually, you can find Him in a big pile of other Walruses, usually a hundred or more. Walrus communicates with his Friends with knocks, bells, clacks, and whistles. However, if Someone takes up too much room, Walrus will poke Him with his tusks, forcefully telling the other Walrus to “Move over.”

Walrus uses his distinctive mustache to search for food. He feels the sandy bottom with his sensitive whiskers. When Walrus finds a Clam, He squirts high power jets of water out of his mouth. He uses his talent to imitate a water drill to loosen the Clams living under the mud. Afterwards, He sucks up the Clams like a vacuum cleaner.

Walrus has many hidden talents. He moves on all fours as fast as a man can run. He uses his “squirt” to get clams. Walrus’ strong sense of touch comes from his mustache. There is a lot more to Walrus than his tusks. Remember how Walrus uses his talents and learn how to use yours.
