it just does its nature
Crayfish are crustacean which has a hard shell so htey are invertibrates. (No Back Bone or Spine.)
The Black Codes were laws instituted in the South during Reconstruction that aimed to restrict the rights of newly freed slaves and force them into involuntary labor arrangements that mirrored slavery. These codes placed harsh restrictions on African Americans' freedom of movement, employment, and civil rights, effectively attempting to maintain a system of white supremacy and control over the black population.
What my dad would do is close to shore take greasy bakon and line it up on the sides and in the back then it would come into the area and then it would be right there next to you and you could then grab it right there.
Chase it into a coffee mug. Then put it back in.
it refers to forcing fluid in the opposite direction from which it normally flows
The dorsal side is its back, and the ventral side is its 'stomach'. The crayfish is vulnerable on its soft underbelly - the ventral side.
I think from disecting a crayfish in my Biology class, that crayfish have 5 sets of different appendages. All in all, the crayfish we disected had 36 actual appendages. Appendages are areas on an animal that "stick out". Kind of like our arms and legs except crustaceans and other animals have more, and can grow them back if they are cut off. Like I said, total, our crayfish had 36 appendages from anterior to posterior. There are a total of 38 appendages, 19 on each side.
Be your self for them,and if they don't like you for you there not the right guy!
a lot of people died when the black death was around and a lot moved. well the people waited awhile to move back because they were scared that they would get the black death. but after the people moved back the businesses have been back to normal
Lobsters do not have internal skeletons, but they do have external skeletons (exoskeleton), which are their shells.
