Baby Puffer Fish
Pufferfish are among the most poisonous vertebrates on the planet, with most of their species being toxic. To keep predators at bay, this fish has some unique 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 shape.
Baby Walrus
The large flippered marine animal is just as adorable as the other baby animals on this list when it is young. These animals can grow to be quite 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, looking for benthic bivalve mollusks to eat. They typically live in shallow waters above continental shelves.
