A Zone

the area corresponding to all the animals that live in the ocean surface.

1. Starfish

The asteroids are echinoderms, relatives of sea urchins, which are commonly known as starfish.

There are about 2,000 species of starfish that live in oceans around the world, from tropical habitats to cold beds of sea. The most common are five tips, which is why they are called stars, but species with 10, 20 or 40 arms.

They have a calcareous skeleton that protects them from most predators and many have bright colors which allows them to camouflage or scare off their attackers. They are marine animals (there are starfish freshwater) and only a few live in brackish water.

2. Manta Ray

The manta ray, or giant manta (Manta birostris) is a species of elasmobranch Rajiformes enforcement. Unlike other species of the order, no poisonous stingray sting in the tail.

It is the largest of the rays and can grow to 8.4 meters in size and weigh around 1,400 kilograms.

3. Octopoda

Octopods (Octopoda, the Greek, octo, eight, and Podos, "foot") are an order of cephalopods commonly known as octopus. Lack of shell and have eight arms. They are marine and carnivorous animals.

The eight arms of the octopus equipped with sticky suckers and converge on the body of the animal; at their point of convergence presents the mouth, with a corneal peak. Eyes in the head, highly developed brains and three hearts, two pump blood to both gills and the third to the body are housed. The blue color of the blood is because octopuses, cuttlefish and squid use hemocyanin instead of hemoglobin as tranportadora oxygen molecule containing hemocyanin copper instead of iron. In the rest of the mantle organs are located, as the ink they use to escape predators; also have a siphon, which unlike the squid, can change direction with which ejects a large amount of water, thus promoting a high speed. Each of their arms is connected with a small brain that depends on primary and uses them to control their arms
