Comprehensive Description

Read full entry


 A small shrimp usually up to 43 mm in length (max. length 65 mm). Its colour is dorsally red, with white lateral borders to the carapace and appendages. The narrow rostrum is straight and unarmed, being distinctively pointed and short at the top. There are two antennae, one being a third of the length of the other. The anterior projections of the carapace actually cover the eyes in the dorsal view. The chelae are noticeable dissimilar in size with a normal join of the dactyl. The third thoracic appendage is slightly longer than scaphocerite (outer/exopod branch in antenna). And the tail fan/telson has two pairs of lateral spines.The shrimp produces the snapping sound by an extremely rapid closure of its large snapper claw. The loud snap has been attributed to the mechanical contact made when the dactyl and the probus edges hit each other as the claw closes. The snapping plays an important role in intraspecific communication. In addition, it is used to defend a shelter or territory and to stun and even kill prey (for example see Versluis et al., 2000).
