Me and my partner, Angel and Ni, dissected a crayfish and cricket. I labeled all four pictures the antennaon both dorsal view and Ventral and side view. Some features that crayfish and a cricket have are antennle, eye, rostrum, cheliped , middle leg, cercus, lambrum, ocellus. I searched a crayfish environment they live in any kind of water except for salt water. And crickets live along roads, warm places, damp place.Some of the adaptions of a crayfish is that they have very large claws like a lobster and can swim backwards very quickly. And a crickets adaption is that they adapt by the surroundings of them.The antenna is proximal to the cricket and crayfish face. The middle leg of a cricket is posterior to the stomach.
I noticed that when you dissect a cricket you could see the guts but on a crayfish you really can't. I'm still unsure about why you couldn't open the crayfish with the knife? I learned how to dissect a Worm and I saw what it has inside of it mostly poop. I never knew that a worn can be really big i think it was like 6-7 inches long. Dissecting an animal is kind of gross.
