Does the crayfish have a muscular system?

Crayfish have muscles. They need them to move.


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.


What 2 systems of a crayfish are most unlike human systems?

Exoskeleton: Crayfish have a hard shell, and no bones. That makes crayfish invertebrates (no spine). Gills: Crayfish respire underwater through gills, where humans use lungs. The circulatory system is the second one, the reason for this being that crayfish have no blood vessels (and humans obviously do).


Do crayfish have a skeletal system?

yes


Does a crayfish have a open or closed circulatory system?

Crayfish, along with all other arthropods, have an open circulatory system. There are no veins and no separation of blood from interstitial fluid.


Of the crayfish systems what two are the most unlike the humans systems?

The excretory system of crayfish, which involves specialized structures called green glands for waste removal, is unlike the human excretory system, which primarily relies on the kidneys. The respiratory system of crayfish, which involves gills for gas exchange, differs from the human respiratory system that uses lungs.

Circulatory ?


What is a nephridiopore in a crayfish?

Nephridiopores in crayfish are part of their excretory system (for removing nitrogenous waste); crayfish propel water from the rear to the front and out the nephridiopores. It is analogous to how humans have to expend their liquid waste.


Does a crayfish have an open circulatory system?

Crayfish, along with all other arthropods, have an open circulatory system. There are no veins and no separation of blood from interstitial fluid.


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.


Compare grasshoppers circulatory to that of a crayfish circulatory?

This idiot is wrong. Maybe if you paid attention in Ms. Roberts class you would know that grasshoppers have a closed ciculatory system and crayfish have an open with very dark blackish blood. They do not have purple or green blood.
