It can get pretty technical, but it can be done. First, you'll have to turn it over and hold it (or put it in a clear bottomed container and look underneath). The best photos I can find have captions in a foreign language, but I can try and explain what these are showing: http://www.crayfishworld.com/sexy.htm
Crayfish have four pairs of legs, numbered 1 (closest to head) through 4 (closest to tail). In the photos in the link, the head is always to the left. One of the easiest features to see is the swimmerettes - these appendages look like little gills and are paired on the segments behind the last pair of legs. In females, the first pair is small or missing - in the males, they are well-developed. The swimmerettes can be seen in the second and third paired photos.
A little more difficult to see, but there are differences in the position of the pores that are the genital openings - where sperm or eggs are deposited - these are shown in the top pair of photos. In the males, the pores are at the base of the fourth pair of legs. The female has oviduct openings at the base of the second pair of legs.

How did you ever manage to keep a crayfish alive anyhow? I have never ben able to do so although nearly everything else I kept did very well in captivity. Did you know a female crayfish carries her eggs underneath her tail?

Based on solid scientific evidence, the octopus is one of the most intelligent invertebrates out there. It is able to open a bottle, recognize colors, etc. The only thing not cool is the blue ringed octopus that resides in Australia- one bite from it and you're likely to be overwhelmed by the poison in 30 minutes.
