It's the first time I use this website and I really need help because I'm totally stuck
Now I'm in school, but I'm trying to prepare for the Olympics During the preparation, I found the issue on the anatomy of the animals, but it's something new for me - I can't even determine what it is!
What kind of animal is it? Could you determine some, the most vital and major of highlighted points? If you can help me to determine the kind of it, i will be able to use more specific books to find out.
I will be very grateful for any help!
