Echinoderms body description?
Echinoderms are a phylum with usually 5 fold symmetry, spines and calcium carbonate plates.
How many body openings do echinoderns have?
Adult echinoderms only have one body opening. Their larvae have two.
What is the body symmetry of fish?
clown fish have bilateral symmetry
What is the major difference between echinoderms and other invertebrates?
The major difference between echinoderms and other invertebrates is that there are few examples echinoderms that do not live in ocean water and none live on land. There are examples of other invertebrates that live in both fresh and salt water and on land. Echinoderms also display radial symmetry as do the jellyfish and sea anemones. If you want to tag the one thing that echinoderms have that no other living invertebrate has, you would probably have to point to their water vascular system (see link). If you have the McGraw Hill science textbook for 6th grade then you are all set. Look on pages A40-A48.
What kind of symmetry do sea slugs have?
Crustaceans, like all arthropods, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
What structure do echinoderms use to move and to open shells of mollusk?
tube feet
What is example of echinoderms?
Echinoderms can only be found in water, as they are aquatic. Some characteristics of Echinoderms are: Hard Skin, have arms or spines, have 5 body parts, organs found towards centre of body. Examples: Star Fish, Sea Cucumber, Sea Urchin
Which are the types of symmetry seen in invertebrates?
Yes they are. Symmetrical organization means when you can draw a line down the middle of the organism and the two sides look like mirror images. If you draw If you draw a line down the middle of an octopus you would find two sides with equal parts. Sponges and some coral are not symmetrical tho.
Does Echinoderms have a body cavity?
Yes it does
What type of symmetry do sea urchins have?
Seahorses are fish; therefore, like all vertebrates, they have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
