When L. clathrata loses part or all of an arm through predation, it can regenerate the limb.The damaged area is sealed off, and a new small arm-tip appears within a week. Subsequent development is at the rate of about 3.7 mm (0.15 in) a month, although this slows down when regeneration is nearly complete.
