Blue Whale

Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet long and upwards of 200 tons. Their tongues alone can weigh as much as an elephant.

Scorpion Fish

Scorpionfish have extremely potent venom in their sharp spines, making them one of the most poisonous animals in the ocean

Brisingid sea star

They have as many as 20 arms, each one bristling with spines. These spines are covered in thousands of tiny snapping jaws for capturing prey

Giant Isopod

The giant isopod has no spine. It's a crustacean — cousins of crabs and shrimp

Red Crab

Red crabs dig burrows or live in deep rock crevices. They are sensitive to a lack of moisture and rarely leave their burrows during the dry season, plugging the entrance with a wad of leaves. They mostly eat fallen leaves, fruits, flowers and seedlings.

Goose Fish

Goosefish are marine bottom-dwelling fish that prefer sand, mud, and broken shell bottoms from inshore areas to depths greater than 2,000 feet. They are voracious predators and feed on fishes and other prey almost as big as themselves.

Octopus

Octopuses have three hearts.

Octopuses may be so terrifyingly smart because they share humans' genes for intelligence

Skate

The skate's tail lacks the stinging spines found in electric rays. They are innocuous bottom dwellers, often found lying partly buried. They swim with a graceful undulating movement of their pectoral fins. Skates feed on mollusks, crustaceans, and fishes, trapping active prey by dropping down on it from above.

Jelly Fish

Jellyfish are 95% water

They have very short lifespans

Some jellyfish can turn back their biological clock
