studying the different morphologys there were in the different crab species found in relation to the types of wave exposure. low, as in an esturary or harbour. intermediate wave exposure as on a shore where the waves are some what lessoned by stumps and rocks before the shore line. and high impact where the full force of the wave hits the shore line.  you will notice that sediment at all these sites is different adn this is reflected in the crab s morophology and species.  measure the carapace width and length, the length and width of the chela, take note of the crabs species and where it was found. all sorts of comparisons can be found. this was a very indepth study we did but it can be scaled down to suit a short time fram.  please if you are truley interested i would only be too happy to send you more information.

Groin is like a intracostal (rib) there is little to do but rest. However to help the pain take advil and ICE (20 min no more).. dont use heat..also try to avoid side to side movements..Inductor adductor movement will assuridly restrain that area...groin pulls take time to heal..be patient..

Go for a wooden one that can be extended. Usually, the back third can be replaced by an extention that you use when using the rest. Avoid gimmick cues like aluminium and carbon fibre. Leave those to the fishermen!
