This video offers an informative look at the ecological impact the British Columbia sea otters are
having on the marine life of the coastal reef. Sea Otters can be enjoyed by students of many
ages and can be used in segments or in its entirety, depending on the teacher's intentions.
"When Mother Nature decided to dress the sea otter, she must have been feeling generous."
Their special coat is described in detail--100,000 human hairs in comparison to 800 million
hairs on the sea otter. The texture and cleanliness of their hair are integral to their
survival in the cold waters in which they live. Because the sea otter was close to
extinction in 1911, there was a ban put on its being hunted. This ban benefitted the coastal
reefs in a significant way. The sea otters' diet includes sea urchins which were destroying
the reefs. They eat all the kelp on the coast, and, when there are too many sea urchins in
one area, they destroy the ecological system.
The video provides much factual information, including the point that the sea otter eats
one-third of its weight and burns up three times as much as a land animal of the same size.
Their energy is seen in the constant turning and flipping in the water which keeps them
warm. They eat 9000 pounds of food each year, which, in terms of people food, equals 100
hamburgers each day for a year. They are the only mammals that use utensils to eat their
food and are lucky to have few natural enemies.
Sea Otters is a bit long to keep a younger student's attention; it goes back and forth between
sea otter expert Jane Watson and the narration of the sea otter's survival skills and natural habitat.
