10. Which sea animal that is always found in or underwater, is totally white, is very vocal, always wears a smile, and can swim backwards?
From Quiz Found Underwater
Answer:
beluga whale
The beluga whale is a very interesting sea mammal. Though it is warm-blooded, it lives in some of the coldest temperatures in the ocean. It had a layer of blubber under its white exterior that helps it keep warm, and it is a very vocal animal. In addition, it always appears to be smiling. You wouldn't think that it would be as agile and graceful as it is, given its size, but it is the only animal of its kind that can swim backwards!
The other options do not fit the bill here. The great white shark is not as white as the beluga (it is actually gray on top and white on the bottom), and it cannot swim backwards. Sharks don't have vocal cords, so they are not vocal either! Polar bears do spend time in the water and they are white, but they do not live underwater. They do growl, however, so they are vocal. The unicorn is not found underwater, and is actually not found at all in the real world, since it is a mythical creature. There are no tales of it being able to swim backwards, either.
