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.
