This week in science #8


The picture on the left is the ventral view of the crawfish Yasmin and I dissected, and on the right is the dorsal view. The dorsal part was where my partner Yasmin the open to observe the inside or the crawfish. What I labeled on the picture was the abdomen. This feature is the most distal part of the crawfish. Distal is the back or spine of the body or in this case of the crawfish. The proximal part of the crawfish would be the eyes. Proximal means the closes part to the body. The eyes are located in the anterior part of the body, meaning on the head area. The abdomen is located in the posterior area, mean the abdomen is around where the tail is at. You can tell by the picture this is true. The environment of the crawfish is surrounded by fresh water they mostly live on the muddy bottom area of the body of streams or pounds.


while doing this project i was honestly very disgusted because of the crawfish's guts coming out of it. It wasn't pleasant. Other than the disgusting part i did actually learned something. I didnt know that the crawfish's liver is yellow, but after dissecting the crawfish I saw something yellow then i asked Jamie what it was and she told me its was the liver.
