Belugas
Belugas
- Belugas have an excellent sense of hearing; their ability to echolocate appears to be even better than that of a bottlenose dolphin!
- Unlike most whales, some belugas enter rivers during the summer.
- As much as 40 percent of a beluga’s body weight is blubber.
- A beluga can nod and turn its head because, unlike most whales, its seven neck vertebrae are not fused.
- Belugas play with food, driftwood and air bubbles.
- A sea otter’s skin never gets wet.
- River otters, weasels, and badgers are sea otter relatives.
- Sea otters dive frequently for food; a typical dive is 30 m deep and lasts 45-127 seconds.
- Large complex kidneys make it possible for sea otters to drink salt water.
- Predators include killer whales, sharks, and sea lions: bald eagles prey on pups.
- They are one of few tool-using mammals; sea otters use rocks to break open their food.
