The Great White Shark has existed for over 450 million years and can grow up to 9 meters long. It has a complex circulatory system that allows it to maintain a higher body temperature than the surrounding water. While it will eat almost anything, it often mistakes humans for its usual seal prey due to their similar shapes. Great White Sharks typically live 30-50 years.

Killer whales, or orcas, are the largest members of the dolphin family. They can grow up to 32 feet long and weigh as much as 22,000 pounds. Killer whales are found in all oceans and can live for 30-60 years. They communicate through clicks, whistles, and pulsed calls. Killer whales hunt fish, squid, sea lions, and other marine mammals. There are two ecotypes - residents, which live in family groups and transients, which live in smaller groups and prey on other marine mammals.
Birds are characterized by feathers, wings, a beak or bill, laying eggs, a lightweight skeleton, and molting. Feathers are made of keratin and have several functions, including flight, insulation, incubation, courtship, and waterproofing. There are two main types of feathers - pennaceous feathers which form the wings and tails and provide lift, and plumulaceous feathers which are wispy and insulative. Birds have strong flight muscles and either monogamous or polygamous reproductive behaviors, where they build nests and care for altricial or precocial offspring after laying clutches of eggs.
