No, crayfish are invertebrate animals, they do, however have an exoskeleton which makes up for the lack of a backbone.
Yes and no, no one would help me on this question so ask someone else
yes i believe they do
A crayfish has segments, which are sections of a body that are separated by a crease, so it might be determined as segmented because it has only two so it may be classified but it might not. Worms have many segments.
ventral, i think...
Macro invertebrates are organisms with no backbone or spine that can be seen without the use of microscope. The best examples are flatworms, crayfish, snails, clams and dragonflies.
A crayfish is a crustacean, which means that it has a shell and does not have a backbone, therefore it is an invertebrate.It has an exoskeleton, meaning its support is on the outside, not on the inside.It is an invertebrate.
Most animals are more highly protected on their dorsal side. The dorsal side is the backbone side if the animal has a backbone. Most of the harder bones and protection is on that side. The ventral, or belly side, is almost always more vulnerable and softer.
