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.
A crayfish has an open circulatory system while humans have a closed circulatory system. "Closed" means that we have true blood vessels that carry blood to and from the heart. "Open" means that the organs are simply bathed in blood that freely circulates around the body. Sometimes the heart can move the "blood" by creating pressure waves in the fluid.
Yes, most arthropods have an open circulatory system, which means that their blood, called hemolymph, directly bathes their tissues. This system is less efficient at transporting oxygen compared to closed circulatory systems found in vertebrates.
In cephalopods like octopuses, the circulatory system is closed, with blood contained in vessels. Bivalves like clams have an open circulatory system where blood is pumped into a hemocoel. Gastropods, such as snails, have a mix of closed and open circulatory systems, with a heart that pumps blood through vessels but also into spaces around organs.
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
Crayfish are omnivores, meaning they are both an herbivore and a carnivore.
In crayfish, gills are required to perform respiration whereas grasshoppers get oxygen for respiration straight from the atmosphere.
grasshoppers, have an open circulatory system
These creatures are a like because they both have antennas. They are different because grasshoppers breath through little spirals, but crayfish breathe normaly.antenna, madible, walking legs
Grasshoppers have an open circulatory system which might answer this question.
Crayfish, along with all other arthropods, have an open circulatory system. There are no veins and no separation of blood from interstitial fluid.
Circulatory ?

Grasshoppers have an open circulatory system, and worms have a closed circulatory system. There you go. :)
Yes, grasshoppers have an open circulatory system. This means that their blood is not enclosed within vessels and instead bathes their internal organs directly. The blood, called hemolymph, circulates through the body cavity.
Grasshoppers have spiracles that help them breath whereas crayfish breath through gills.
