fascinating animals that dwell in the ocean.

The fascinating Peacock Calanid can be found in the Mediterranean Sea and in Atlantic, Indian and Pacific

Oceans. Before its discovery in Ireland, it does not appear to have ever been recorded further north than the

Mediterranean. This flamboyant animal prefers warm waters and its presence in Irish waters is a rare occurrence.

It can be found as deep as 2,000 fathoms or 3.7 km. It has beautiful patterned feathers and males are much

 more moderately decorated.

(260 feet). It is filter feeder and like the real tulip flower, Sea Tulip comes in a variety of colors like white, pink,

yellow, orange, and purple. Its coloration depends upon its association with a symbiotic sponge that covers its

surface.

This organism looks like a plant but it is not. It's a marine animal called Crinoid or informally named as Sea Lily

 or Feather-stars. It lives both in shallow water and in depths as great as 6000 meters. The anus of this marine

animal is located next to the mouth.

Tunicates. Tunicates are commonly known as Urochordates, Sea Squirts or Sea Pork. These are underwater

saclike filter feeders with incurrent and recurrent siphons.

This creature is a sea apple cucumber that contains holothurin and holotoxin which can be released even after

death. So if you decide to keep this species in a tank with fish, it is like planting a ticking time bomb because even

its eggs are poisonous to all fish. It has been imported for many years in the marine hobby because it is beautiful,

fascinating to watch and make excellent tank janitor. It is the most poisonous sea cucumber.

Purple Sea Urchin (Strongylocentrotus purpuratus)

predators. This urchin is deep purple in color and grows to a diameter of about 4 inches. It is found along the

Pacific coast of US and Canada where it clings to depressions in the rocks during low tide.

to a length of 50 cm and a width of 5 cm. It is found from the low intertidal zone to a depth of 250 meters.

Crown-of-thorns Starfish of the Indo-pacific region has orange-red to purplish skin, with yellow or pink spikes on

their skin. These bright colors are warning that it is venomous. The Crown-of-thorns is the largest sea star in the

world. It can grow to a diameter of up to 3 feet.

These marine animals are well known for its destructive habits of eating coral, which may lead to the destruction

of coral reefs. A few Crown-of-Thorns help maintain the coral reef by preventing the faster-growing coral from

taking over the coral reef but when there are too many Crown-of-thorns, they can devastate a coral reef.

Basket Star (Eurialida)

 has no freshwater or terrestrial representatives.  Brittle stars are not used as food even though they are non-

The fantastic-looking Giant Sea Star lives along the western coast of North America from Southern California to

British Columbia. It makes its home on rocky shores near the low tide mark. It feeds on mollusks and can grow as

 a close look at its teeth - it can be considered one of the most unusual-looking fish in the world.

This bizarre fish can reach a size of 91 cm and a weight of 16 kg.  Here's another peculiar thing about

Sheepheads - they are born as females and eventually change to males. The age of the transition depends

looking fish inhabits lagoon and seaward reefs and can also be found around coral reefs and in tide pools. It

grows very slow making it an ideal tank fish. It feeds on small fishes and crustaceans. Juveniles are commonly

caught for the aquarium trade while adults are utilized as a food fish.
