Species of animals in the Sea.

1. Species of animals in the Sea. Made by Kimberly Zammit and Jelena Attard.

2. Whales • Whales are large, magnificent, intelligent, aquatic mammals. They breathe air through (blowholes) into lungs (unlike fish who breathe using gills). Whales have sleek, streamlined bodies that move easily through the water. They are the only mammals, other than manatees (seacows), that live their entire lives in the water, and the only mammals that have adapted to life in the open oceans. Whales breathe air. They are NOT fish. They are mammals that spend their entire lives in the water.

3. Whales • Whales have hair (although they have a lot less than land mammals, and have almost none as adults), • Whales are warm-blooded (they maintain a high body temperature), • Whales have mammary glands with which they nourish their young, • Whales have a four-chambered heart.

4. Penguins • Penguins are birds. Most of them live in the sub-Antarctics and on Antarctica. However, the Galapagos penguin lives around the equator. There are no penguins on the North pole, nor are there ice bears on the South pole. • Unlike most other birds, penguins can't fly. They waddle on land and swim in the sea. When swimming fast, they jump out of the water every few meters, just like dolphins do. This is called porpoising.

5. Skin and colour of penguins. • The top layer of a penguin's skin is made of thousands of small, stiff feathers. The air between the feathers is good insulation. To make their 'coat' even more water- and windproof penguins spread some oil on it. Below the feathers is a thick layer of blubber to keep the penguins warm. • Once a year, penguins shed their feathers and grow new ones. This is called melting. The old feathers come off in patches and at the same time new feathers grow. All penguin backs are black and all bellies are white. This has to do with swimming camouflage: the black back looks like the bottom of the ocean and the white belly looks like the water surface.

6. Clown Fish • Clown Fish are commonly found in the warm waters. The Pacific Ocean, the Red Sea and the Indian Ocean are some places where Clown Fish abound. The most common home for the Clown Fish is among the tentacles of the Sea Anemone. It’s a curious quirk of nature that the tiny Clown fish is able to live without getting stung by the tentacles of the Anemone. The fish actually uses the Anemone to save it from predators.

7. Turtles • Adult turtles may go to different feeding grounds altogether, and when sexually mature will travel to breeding areas to mate. Gravid females come ashore on tropical nesting beaches to lay their eggs – a hundred or more at a time, in nest pits that they painstakingly excavate with their hind flippers. The process of finding access to the beach, hauling a huge body built for aquatic life onto gravity encumbered land, then crawling with flippers made for water across wide swaths of sand, rock, and berms, is extraordinarily difficult.

8. Sea Lions • Sea Lion, intelligent, slender-bodied seal, well known for its balancing acts as a circus performer and its presence in almost every zoo. In the wild, these shore-living seals are found along many areas of North America’s western coast, from British Columbia southward through the United States to the Tres Marias Islands off of Baja California, Mexico. Adult males, called bulls, average 360 kg (800 lb) in weight and 2.1 m (7 ft) in length. Females, or cows, are smaller, with an average weight of 110 kg (250 lb) and an average length of 1.8 m (6 ft). Both sexes have chocolate-brown coats and doglike muzzles

9. Sharks • What are sharks?! • Sharks are amazing fish that have been around since long before the dinosaurs existed. They live in waters all over the world, in every ocean, and even in some rivers and lakes. Unlike bony fish, sharks have no bones; their skeleton is made of cartilage, which is a tough, fibrous substance, not nearly as hard as bone. Sharks also have no swim bladder (unlike bony fish).

10. Sharks • Some sharks live near the surface, some live deep in the water, and others live on or near the ocean floor. Pelagic sharks include the great white shark, the basking shark, etc. Benthic sharks include the zebra horn shark, the wobbegongs, and the angelshark, which usually have flattened, camouflaged bodies that let them hide in the sea bed. Some sharks even venture many miles up into the fresh water of rivers like the Mississippi in the USA and the Amazon in Brazil. The bull shark (Carcharhinus leucas) sometimes ventures into fresh water.

11. Dolphins • All dolphins are toothed whales belonging to the sub-order, odontocetes, of the order cetacea (see section on humpback whales for more information). As a group, dolphins are often referred to as "small" cetaceans, even though some of them are quite large, attaining lengths of over 20 feet. In addition, although the terms dolphins and porpoises are often used interchangeably, they really refer to two different types of animals.

12. Dolphins • Most dolphin species are about 6 ft in length, the males averaging 4 to 8 in longer than females.  One of the largest dolphins is the bottle-nose dolphin which can reach over 9ft in length and weigh 440 lbs.  The smallest species is the buffeo, found in the Amazon River.  The buffeo rarely grows over 3.9 ft in length and 66 lbs in weight, really smalled compared to the bottle_nose. The primary food is fish, mostly things like herring, mackerel, and sardines. 

13. Dolphins • The body is sleek and smooth and the hairless skin is rubbery to the touch.  Most species have jaws that protrude into a beak like snout.  Above the upper jaw is a large mass of fat and oil-containing tissue forming the so-called "melon" that looks much like a bulging forehead.
