Starfish or sea stars are echinoderms belonging to the class Asteroidea.[2] The names "starfish" and "sea star" essentially refer to members of the Class Asteroidea. However, common usage frequently finds "starfish" and "sea star" also applied to ophiuroids which are correctly referred to as "brittle stars" or "basket stars".
There are 2,000 living species of starfish that occur in all the world's oceans, including the Atlantic, Pacific, Indian as well as in the Arctic and the Southern Ocean (i.e., Antarctic) regions. Starfish occur across a broad depth range from the intertidal to abyssal depths (>6000 m).
Starfish are among the most familiar of marine animals and possess a number of widely known traits, such as regeneration and feeding on mussels. Starfish possess a wide diversity of body forms and feeding methods. The extent that Asteroidea can regenerate varies with individual species. Broadly speaking, starfish are opportunistic feeders, with several species having specialized feeding behavior, including suspension feeding and specialized predation on specific prey.
The Asteroidea occupy several important roles throughout ecology and biology. Sea stars, such as the Ochre sea star (Pisaster ochraceus) have become widely known as the example of thekeystone species concept in ecology. The tropical Crown of Thorns starfish (Acanthaster planci) are voracious predators of coral throughout the Indo-Pacific region. Other starfish, such as members of the Asterinidae are frequently used in developmental biology.
There is a hole in the front and back of the sea cucumber, the hole in the front is where it eats. The hole in the back is where it poops and breathes.... There are tentacles on their heads and they use them for picking up food.
How do sea cucumbers get rid of waste?

Differences between sea urchins and sea cucumbers?
Echinoderms are a category of sea invertebrates; there are 5 groups of echinoderms, Asteroidea, Crinoidea, Echinoidea, Holothuroidea and Ophiuroidea. A sea cucumber is a holothuroidea; their lengthy body surrounded by leathery skin identifies holothuroideas. A sea lily is a crinoidea; crinoidea feed off the seabed with a mouth at the top of their body.
The Sea Cucumber is a soft-bodied invertebrate that is related to the starfish and sea urchins. There are over 1100 species that are found worldwide in intertidal zones as well as deep waters.
Does a sea cucumber have a tube feet?
Yes; all over its body. But its muscles can also move the spines!
Is sea cucumber classified in the Kingdom Plantae?
the sea cucumber is in the animalia kingdom hope it helps you! :) :) <3
Does the sea cucumber have only a few ossicles?
The word "ossicle" means "little bone"
The sea cucumber has calcified structures just under the skin which are called microscopic ossicles or sclerietes. There are many of these ossicles which are remnants of a previous endoskeleton.
Does a sea cucumber have a head?
yes im a scientist myself and study living organs a sea cucumber does have a heart xx
Sea Cucumbers have a variety of colors, depending on the species. Most are a light orange, brownish-orange, or a reddish-brown. Also, some species have a projections similar to spikes which are black.
Don't use a carrot i heard someone died because it teared the skin so be careful
What is the length of a baby sea cucumber?
The warty sea cucumber can grow from 9 to eleven inches in length and get 4 to 5 inches tall. Other sea cucumbers (like the California Sea Cucumber) can grow to be about 16 inches. There is no overall average length of all the Sea Cucumbers. Every Species has its own length.
yes the sea cucumebrs are endangered because people or any other life hunts them and kills them
