Starfish

It depends what type of starfish you are talking about and whether it is in its own environment or introduced. If it is in its natural environment, it would eat and be eaten, but if it is an introduced species (e.g. Northern Pacific sea star) it may not have any predators and be competing for food with the native wildlife.

It doesn't help the starfish move it

helps it so it can eat.

Sea Stars otherwise known as Star Fish are Echinoderms and they do not have an exoskeleton, they have an endoskeleton.

Trains.

Yes, starfish are able to regenerate their limbs.

they use the insides as a type of medicine

Sea stars are prey of sea turtles, basking sharks, sun fish, and many other sea animals.

Science Online is a great resource for this information. (You may have access through your local library ) According to Science Online an octopus is described as, "An eight-armed marine invertebrate (animal without a backbone). Octopuses are found in all oceans, from the water's edge to depths of at least three miles (4,800 m)" Starfish (now known as sea stars) are also an invertebrate, and as noted by Science Online, "creatures of the class Asteroidea in the phylum Echinodermata." According to Science Reference Library, Echinodermata is further described as, "…have[ing] arms or spines that radiate from the center of their body."

1. No, a starfish is not a fish. Here's my reason
2. The definition of fish is: Vertebrates with fins and tails.
3. A starfish isn't a fish for these reasons.
4. Starfish are Invertebrates.
5. Starfish do not have tails, they have appendages like you and I.
6. Starfish don't have fins.

Invertebrate.

It's called a starfish that likes meat.

they have bones and move them with nervs.

psss.

jk go head nd use it... .. im going to wikipedea tho :v

The echidna is not a large animal, so it has small feet. Unlike its fellow monotreme, the platypus, it does not have feet with retractable webbing. On the other hand, it shares with the platypus the characteristic of feet with very sharp claws for digging.

They do not. Strange as it may seem, many animals don't have heads. Starfish, urchins, coral, sponges, singe celled animals, adult tunicates, jellyfish, and many more, don't have heads.

one pound and a half

The plural is starfishes or starfish.

No. The female releases a large quantity of microscopic eggs out into the water to be fertilized by the male externally. The babies, known as larvae, take about 2-5 years to grow. In all this time, they are not cared for by their parents.

Sea stars like to live in shallow tide pools in the ocean.

totally!!they hav a short backbone but a backbone none-the-less

Sea stars are called asterios forbesii, they are echinoderms, belonging to a class called the Asteroidea, which come to think of it, translates into gods of the stars. Astra:star and dea/deo/deus: god

i think one way to protect a starfish is to feed it and care for it

Sea stars are in the phylum Echinodermata and the subphylum Asterozoa.

The starfish eats algae that is harmful to many species of fish

No. Star fish is not one of the Great Whites regular prey species. They prey upon fish (like Tuna, Rays etc), other smaller species of Sharks, dolphins, porpoises, seals, sea lions, sea turtles, sea otters and even sea birds. They prefer prey that has a high content of energy rich fat. They usually hunt early in the morning before the sun rises fully, when the visibility is poor

Land and aquatic vertebrates are similar in that they both have a vertebral column. They are both either primary or secondary consumers as well. A difference is that vertebrates that live only in the water do not have fully developed hind legs.
