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.

Why does the crayfish hide after the molts?
because it has no protection left.
Why does a crayfish hide after it molts?
After it molts, a crayfish needs some time to grow a new and larger shell. During this time it has no shell to protect it from attack, therefore it hides.
How is the exoskeleton on a crayfish an adaptive advantage?
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 does the exoskeleton do in a crayfish?
protects the crayfish
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.
Why does a crayfish have to hide when it molts?
The outer covering of a crayfish is it's protection. You may notice that the shell is very hard. This protects it from preditors, that is the reason it hides, to keep itself hidden from pretitores who might attack.
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.
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.
Why does a grass hopper molt?
When the Grasshopper grows, its exoskeleton becomes to small. The grasshopper molts so it can grow a new larger exoskeleton.
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.
