Echinoderms

There is no such thing as an "adult larva" , a larva is always immature ( a "baby"). If you mean "how is a sponge larva different from and adult sponge?" The answer is:

1. The larva is almost microscopic. You can't really see it with your bare eye.

2. the larva swims around. an Adult sponge stays attached to a surface for its lifetime and can't swim

both have a nerve cord

Seahorses tend to like Shallow Waters More than Deep Waters

Actually, echinoderms are more closely related to humans than molluscs.

Echinoderms are the phylum. The phylum is Echinodermata Echinoderms are the phylum. The phylum is Echinodermata Echinoderms are the phylum. The phylum is Echinodermata

starfish poop the same way that they eat, and that is by making their stomach go inside out.

There are many places one can purchase Starfish earrings. One can purchase them online from Amazon or eBay or Etsy. One may also want to check out jewelry stores such as Claire's.

aboral!!!!!

i hate stupid people who get on here and answer things wrong!!!

The radial canals carry water to the ampullae and provide suction to the tube feet.

in the sea....starfish don't live on land.(:

why do people put starfish in the window

No an octopus is a mollusk, just like squids, clams, and oysters. Echinoderms are sea stars, sea urchins, sea cucumbers, sea lilies, sand dollars, basket stars, brittle stars, and feather stars.

Usually in the middle underneath the animal. However the mount can also migrate forward, to the side of the animal in an irregular echinoid.

they are ectothermic because their body temp. is the same as their environment.

Glass, surprise.

No, they are reptiles.

An echinoderm has no spine and either lives in water or terrestrial habitats, they have no brain or skull either. Their skin is made of tiny plates that give it a rough and sometimes spiny feel

Ex:

Starfish, sea urchins and over 50,000 more

Some of them are predators, most starfish are, they eat slow moving creatures like barnacles or clams

A few filter feed

And some eat algae scraped off of rocks

Hope that helped

Yes They Can

On the ventral side of an echinoderm (say, a sea star, for example) there are hundreds of tiny feet arranged into rows on each appendage. These are called tube feet. By varying the internal water pressure, the echinoderm can extend and contract its tube feet for locomotion, food collection, and respiration

Approx. 7, 000 species that fall into five clades(sub-groups)

It is at the bottom of the starfish

First, they are incredibly good at catching and killing their food with very little movement. they have poison which can incredibly help them survive and thrive.

sea lilies and feather stars
