The Smallest Marine Mammal Who Ever Lived (in North America)
The sea otter, the smallest marine mammal in North America, is a member of the weasel family and the only marine mammal that doesn’t have blubber to keep it warm. Instead, the sea otter relies on its thick fur to keep its body temperature around 100 degrees.
Who's Afraid of Little Old Me?
Whale sharks are known to be the largest fish in the world, with some individuals measuring 20 meters (60 feet) long and weighing around 40 tons. But, do not fear! Despite their tremendous size, they are gentle giants, using their nearly 1.5 m-wide (5-foot) mouths to filter plankton out of large volumes of water as they swim. Nothing to be afraid of.
