What is the maximum age of echinoderms?
The maximum age is around 100-130 years sorry couldn't find anything more specific =(
What is the same about all echinoderms?
They belong to the phylum: Marine animals.
Have radial symmetry, a mesodermal skeleton and they all have a water vascular system called: ambulacral.
Where do Echinoderms obtain their energy from?
A echinoderm can obtain resources because if you think about it, The sea urchin etc. they all filter feed that is how they get their food.
Is it harmful if a dog eats a starfish?
Almost all starfish are non-poisonous. The exception that comes to mind is the Crown of Thorns starfish, that carries a toxic charge on its spines. However, it's painful to even pick up, much less eat. I think you're okay on this one.
What do echinoderms use for protection?
Echinoderms are protected by their spiny skins, but are still preyed upon by some types of shells, fish, crabs, shrimps, among many other.

Do some echinoderms live attached to rocks?
Yes, several. Most crinoids are sessile and live their life attached to underwater rocks, as do several starfish species.
How do you know if echinoderms are autotrophic?
No. Porifera (sponges) are heterotrophs. This is a key defining feature of all animals.
How is the body of a echinoderm protected and supported?
Echinoderms, such as starfish and sea urchins, are protected and supported by a unique internal skeleton made of calcareous plates, known as ossicles. These plates form a rigid structure that provides both protection and support while allowing for flexibility. Additionally, the outer layer of many echinoderms is often covered with a tough, spiny skin that serves as an additional defense against predators. This combination of skeletal support and protective skin enables echinoderms to thrive in various marine environments.
What is a sea lilies and feather stars?
well you see my good chum
a feather star is located in the middle of the Arabian desert while the "sea lilly" being derived from the british botonist CPHAT yeaman , is a derogatory name for the common house cat.

Anenome.
What are the four major groups of echinoderms?
There are actually four major classes of echinoderms. These are Crinoidea, Asteroidea, Ophiuroidea, Eichionidea, Holothuroidea, and Concentricyloidea. The animals in these range from sea lilies to sea urchins.
What size do sunflower starfish grow to?
Sunflower starfish can grow quite large, reaching a diameter of up to 3 feet (about 90 centimeters) or more. They typically have between 15 to 25 arms, which contribute to their expansive size. These starfish are known for their distinctive appearance and can weigh over 5 pounds (around 2.3 kilograms).
An echinoderm is a spiny-skinned organism like a starfish. Leeches are soft bodied organisms, so they can't be echinoderms.
What are the main characteristics of echinoderms?
I think you're reading out of a low-level-zoology book, there's actually 14 characteristics. But some of them are really hard to understand, i cant even understand some of them myshelf, but for some that i can understand, I'll type it in
1. Body unsegmented, radial
2.No head, no brain
3.It has a water-vascular system
4.Excretory organs abset( it cant pee)
5.And they can regenerate lost parts.
The other 9 are really hard to understand, i think you wouldn't really understand them
Echinoderms are a phylum with usually 5 fold symmetry, spines and calcium carbonate plates.
all echinoderms live in salt water like in oceans and seas. They are in every ocean. Most adult echinoderms live on the ocean floor in salt water feeding on different sea animals. Many echinoderms can be found in tide pools along beaches or in oceans. the tide pools can support a variety of echinoderms and is changed every time the tide goes out.
There are sea stars under the ice in the Antarctic and up in the north, Bering sea and around parts of northern Europe. Many are meat eating predators while some are grazers of algae.
