Our focus today is:  How to determine the lobster’s gender.


On our tours and during our lecture series, one of the most common questions we get asked is:


“how do you know if it’s a boy or a girl?”


The Swimmerettes

Swimmerettes are the feather-like appendages on the lobster’s abdomen (what is often thought of as the “tail” of the lobster). These swimmerettes are used with the crawlers (or legs) to manoeuver slowly on the ocean floor.



If the first pair are calcified (like tiny, pointy legs) as shown above, it’s a male.



When thin and feathery, it is a female.
