Common Bottlenose Dolphin (pod of 2) - Tursiops truncatus
Common bottlenose dolphins are the most familiar dolphins due to the wide exposure they receive in captivity in marine parks and dolphinaria, and in movies and television programs. T. truncatus are the largest species of the beaked dolphins. They inhabit temperate and tropical oceans throughout the world, and are absent only from polar waters. All bottlenose dolphins were previously known as T. truncatus, but recently the genus has been split into two, T. truncatus and T. aduncus. Although this species has been traditionally called the bottlenose dolphin, many authors have used the name common bottlenose dolphin for this species since a second bottlenose dolphins species, the Indo-Pacific bottlenose dolphin, was described. The dolphins inhabit warm and temperate seas worldwide. Considerable genetic variation has been described among members of this species, even between neighboring populations, and so many experts believe that there may be multiple species included within T. truncatus. The common bottlenose dolphin is grey in color and may be between 2 and 4 metres (6.6 and 13 ft) long, and weigh between 150 and 650 kilograms (330 and 1,400 lb). Males are generally larger and heavier than females. In most parts of the world the adult's length is between 2.5 and 3.5 metres (8.2 and 11 ft), averaging 290 kg (648 lb). Newborn calves are between 0.8 and 1.4 meters long and weigh between 15 and 30 kilograms. The dolphins have a short and well-defined snout, that looks like an old-fashioned gin bottle, which is the source for their common name. Like all whales and dolphins, though, the snout is not a functional nose, which has evolved instead into the blowhole on the top of their head. Their neck is more flexible than other dolphins' due to 5 of their 7 vertebrae not being fused together as is seen in other dolphin species.
Tiger Shark - Galeocerdo cuvier
The tiger shark (Galeocerdo cuvier) is a species of requiem shark and the only extant member of the genus Galeocerdo. It is a large macropredator, capable of attaining a length over 5 m (16 ft 5 in). Populations are found in many tropical and temperate waters, especially around central Pacific islands. Its name derives from the dark stripes down its body, which resemble a tiger's pattern, but fade as the shark matures. The tiger shark is a solitary, mostly nocturnal hunter. It is notable for having the widest food spectrum of all sharks, with a range of prey that includes crustaceans, fish, seals, birds, squid, turtles, sea snakes, dolphins, and even other smaller sharks. It also has a reputation as a "garbage eater", consuming a variety of inedible, man-made objects that linger in its stomach. Though apex predators, tiger sharks are sometimes taken by groups of killer whales. It is considered a near threatened species due to finning and fishing by humans. The tiger shark commonly attains a length of 3.25–4.25 m (10 ft 8 in–13 ft 11 in) and weighs around 385–635 kg (849–1,400 lb). It is dimorphic, with exceptionally large females reportedly measuring over 5 m (16 ft 5 in), and the largest males 4 m (13 ft 1 in). Weights of particularly large female tiger sharks can exceed 900 kg (2,000 lb).
