The eye-movements of the mantis shrimp Odontodactylus scyllarus (Crustacea : stomatopoda)

Odontodactylus scyllarus makes discrete spontaneous eye-movements at a maximum rate of 3/s. These movements are unpredictable in direction and timing, and there is no detectable co-ordination between the two eyes. The eye-movements were measured with a computer-aided video method.

Description
Summary:Odontodactylus scyllarus makes discrete spontaneous eye-movements at a maximum rate of 3/s. These movements are unpredictable in direction and timing, and there is no detectable co-ordination between the two eyes. The eye-movements were measured with a computer-aided video method. Mantis shrimps also make target-acquiring and tracking eye-movements which tend to be larger and faster than other spontaneous movements. Rotating a striped drum around the animal induces a typical optokinetic nystagmus whose slow phases are smooth, unlike target tracking which is jerky. Eye-movements may therefore be conveniently grouped into 3 classes: targetting/tracking, scanning, and optokinetic.
