Characteristics of a Crayfish:
Four pairs of walking legs and swimmerts. The large front swimmerts with the hooks, indicate this is a male.
Gills and open circulatory system
Antenna and antennule for balance, sense, smell, taste.
and lots of parts.
This was a fun class.
Next up for dissection is the fish!
