I've been trying to get more action shots, this time focusing on cavity eviction behavior in Neogonodactylus oerstedii. The most common attack mode by intruders is what I call "Lunge-strike-coil". The intruder dives in to the cavity entrance head first, strikes and immediately recoils in front of the cavity with the telson brought up to shield against a counter attack by the resident. This happens in less than a tenth of a second. Here a male N. oerstedii is recoiling in open water in front of a female's cavity. He has alread struck and the extended raptorial appendage dactyls offer additional protection against a counter attack.
