Baby Puffer Fish
Anyone who’s seen the hit TV show Spongebob Squarepants is familiar with pufferfish behavior. Or at least a smidgeon of it. The majority of pufferfish species are toxic, and they are among the world’s most poisonous vertebrates. To ward off any predators, this fish has some special natural defenses. It can use its tail for a quick evasive burst of speed to get away from danger, and if that fails, it can fill its elastic stomach with water (or air if it’s not in the water) until it expands and becomes spherical in form.

Baby Walrus
The big flippered marine animal is just as cute as the other baby animals on this list when it is tiny. These animals can grow to be very large as adults. In the Pacific, an adult male walrus can weigh over 2,000 kilograms (4,400 pounds). Walruses spend most of their lives on the sea ice, searching for benthic bivalve mollusks to eat. They usually live in shallow waters above continental shelves.
