Sperm whales, which are the largest of the toothed whales. and the largest toothed predators. They feed mostly on medium-sized squid, but also giant squid, colossal squid, octopuses, and fish such as demersal rays and sharks. Encounters between sperm whales and giant squid or colossal squid have never been observed by humans, however many sperm whales have scars which are believed to have been caused by such squids.

Tigers are one of the few big cats that enjoy swimming and are known to take to the water to cool off, hunt for fish, or simply to get from one place to another. Indeed, according to a study published in the Journal of Zoology, tigers have been known to swim distances of up to six miles (10 km) in search of food or territory. Additionally, tigers are also excellent divers, and have been known to hold their breath for up to two minutes while swimming underwater.

Lovely pet.
