This week in science #9

This week in science we dissected animals , my group dissected a perch and a skate. we had to sketch out the animals from different angles from its Dorsal View and Ventral View. then we had to open photo booth and take pictures of it and upload them to google doc's. then we cut the perch into a rectatangle shape and we had to first locate the gill bladder and liver than take them out. with the skate we had to cut a circle in the center of it and look inside.

Earlier this week in science we learned how to use the utensils such as the scapel and the scissors designed espeically for cutting flesh. We also learned at is the Dorsal View.
Ventral View. i learned how to identify if a perch or a skate is male or female. My perch was a female perch and i learned that she was pregnant but most people take that out and make caviar out. in the skate we cut its intestines and we found that the skate had ate a sand crab. how come when my team and i removed its lungs and lever we found some oil behind it.

The two animals i dissected were the skate and the perch are similar because they are both marine animals but there body shape are very different. Both of the animals skin where very tough like the skate had spikes on them and the perch had a lot of scales on it. they both carried alot of water inside of there bodies.Another similarity

the perch has fins and the skate has fins too but the difference is that the skates are bigger.
