Bull sharks are mainly found in the warmer and shallower coastal waters of the southern hemisphere. The bull shark is one of the most common species of shark found worldwide.
The bull shark is able to inhabit both salt and freshwater sources just as happily, with one bull shark known to have swum 4,000 km up the Amazon River in South America, finally ending up in the mountainous Peru.

Whale is the common name for a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla with even-toed ungulates and their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. The whales comprise eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale),
