My ecology class went on a field trip to sample invertebrates in Otter Creek. It was tons of fun! I got too excited with all the insect nymphs and larvae that we caught under the rocks. There were also many crayfish. It was my first time capturing crayfish with hands. I found they don't really pinch. It might be because the crayfish we caught were not very big.
The other species we found include mayfly, stonefly, caddisfly, dobsonfly, snail, and midges; they indicate that Otter Creek has good water. Well, too bad that we had to release them afterwards so I didn't have crayfish for dinner. I didn't have the chance to take a picture, so here's a picture from the Internet to show you what a crayfish looks like.
Good day! Very good article and useful information. I was looking buying assignment for a very long time. Thanks for sharing!ReplyDelete
