The exoskeleton on the crayfish is an adaptive advantage because it gives the crayfish support and protection. Unlike humans who have an internal skeleton, the exoskeleton protects the crayfish from its predators. In the case of support, the crayfish's ligament and muscles attach to the exoskeleton, which provides a structure for its internal organs and muscles. The internal skeleton, which provides support, does not provide the same protections as an exoskeleton; however, the exoskeleton also has its disadvantages such as molting. When the crayfish molts, it takes all the calcium out of its previous exoskeleton and holds it in two pockets in its head. The crayfish then flexes its posterior and pushes all the blood toward its anterior, cracking the shell. After climbing out, the crayfish is totally vulnerable to predators because it takes a couple days for the new exoskeleton, which has already developed but is thin and weak, to harden. The calcium stored from the old exoskeleton helps the new one harden, but it still takes a while.

What is the major function of the exoskeleton of a crayfish How is the exoskeleton an adaptive advantage to the crayfish?
The function of the exoskeleton is to protect the internal organs and support the crayfish because it is an invertebrate.
How is the exoskeleton an adaptive advantage to the crayfish?
i thought i knew but im not going to lie.I hate spiders
What does the exoskeleton do in a crayfish?
protects the crayfish
What is the shell of a crayfish made out of?
The "shell" of the crayfish, or rather its exoskeleton, is composed of the polysaccharide chitin and some lipids. There are also some calcium salts in the exoskeleton of the crayfish, which gives it its firmness.
Why does a crayfish hide after it molts its exoskeleton?
After shedding its exoskeleton, a crayfish hides because it becomes vulnerable to injury and attacks from predators. The crayfish sheds its exoskeleton when it needs to grow. It can take two to three days for a crayfish to re-grow a new and larger one.
What color are Crayfish when they first shed their exoskeleton?
After molting their exoskeleton, crayfish are a deep red colour. Some may be lighter than others.
What is the same about a crayfish and a crab?
They are shellfish, they have an exoskeleton.
What is a crayfishes protection?
crayfish have a hard exoskeleton and large, pinching claws.
What two characteristics make a crayfish and arthropod?
Crayfish are classified as arthropods, because of their characteristic segmented bodies, chitinous exoskeleton, and joint appendages.
What is the composition of the exoskeleton of a crayfish?
Their exoskeleton made out of the structural polysaccharide "chitin" (i.e. a sugar polymer).
What do crayfish have instead of bones?
An exoskeleton - i.e. a shell.
Does a crab have a skeleton?
Lobsters do not have internal skeletons, but they do have external skeletons (exoskeleton), which are their shells.
