in the class about grasshoppers and crayfish i learned that both grasshoppers and crayfish are arthropods and have hearts but no blood vessels. i liked that we got to dissect both of them because they where both very interesting. i could not figure out the sex of my crayfish but other students could so i just went with it.
a lot of students had eaten crayfish an said they where tasty. I'm vegetarian so i wouldn't know. but they look tasty.
