Lobstering - Know Your Foe

This little guy will be safe from divers for a while. Notice how the tailings of his excavation are a different color than the surrounding bottom.

Lobsters, like most invertebrates, have a much slower nervous system than our own. In tiny creatures, such as insects, this is no great disadvantage, since their "wire runs" ( or nerves ) are so short. However, in bigger invertebrates, this translates into very long reaction times. Therefore, big lobsters have slow reflexes, much slower than even humans. Another common invertebrate trait is a lack of stamina, at least compared to us. In other words, they tire quickly in a chase. This is not to say that they lack tenacity - once they get a good grip on you, they can hold on forever, and even breaking the claw off may not cause it to release.

Lobsters live in perpetual fear, even big ones, and their first instinct is to retreat from any threat. Their eyesight is poor, and their hearing does not seem to be very good either, although they are sensitive to vibrations. For this reason, swim up to them rather than crawl, and try to use a light only when absolutely necessary. The slightest touch to the sensitive antennae will cause the critter to back quickly into its hole with a flick of its tail. Shining a bright light in their eyes will have the same effect, so be careful where you point your dive light, and try not to use it if you can.

Lobsters like holes and dark places. During the day you will seldom find one out in the open. They are master excavators, and sometimes dig deep tunnels under structure. These holes are often easy to find since there will be a mound or fan of excavated sediment around the opening that is a different color than the rest of the bottom. They will also hide inside any confined place - a crevice, a bucket, a hollow wall. At night, after several hours of darkness, they come out to feed. At this time they are so easy to catch that most states forbid divers from lobstering at night.

Lobstering tails off in October-November through spring. The bigger males wander out to deep water, leaving behind many small males and egg-bearing females, none of which are legal catches. Perhaps one-in-five lobsters you catch at this time will be keepers. At this stage, the females are especially prone to shuck-off claws in self-defense, so it is important to be gentle when catching them, to avoid doing unnecessary harm. Also, once you have caught a short or pregnant lobster, do not put it back in its hole. This will only result in it being molested all over again by the next diver in your group; I have seen some poor females get groped until they have no claws left. Instead, release it in the sand and chase it away - it will find its way home eventually, after all the divers are gone.
