Overview

Comprehensive Description

Shrimp highly mobile occurring in swarms reaching densities of about 2500 ind./m2 on active chimney walls where temperatures range from 10-30°C. Primary consumer, eating bacteria ?cultivated? on the mouthparts, and on the mineral particles ingested. Very few ovigerous females collected, between August and November.

Physical Description

Morphology

Rostrum strongly reduced to very low, broadly rounded lobe. Carapace with branchial region very strongly inflated, distinctly wider than abdomen; dorsal surface rounded; antennal spine modified as broadly rounded lobe; pterygostomial angle somewhat produced anteriorly, broadly rounded; surface with scattered puntae each bearing tuft of short setae. Third abdominal pleuron with posterolateral margin forming light angle. Fourth and fifth pleura with posterolateral angles subacutely or blunly pointed. Telson barely narrowed posteriorly, bearing row of 6-8 dorsolateral spines arranged in sinuous row on either side; posterior margin broadly convex, with 1-3 spines at each lateral angle and with row of numerous plumose setae. Eye-stalks greatly reduced and modified into broad ocular plate. Chela of first pereopod always slender, without fine row of long submarginal setae on outer surface along cutting edges of fingers. Third to fifth pereopods stout, becoming markedly shorter toward posterior; dactyli armed with several rows of accessory spinules on ventral surface; propodi of third and fourth pereopods with covering of numerous spinules on ventral surfaces; meri and ischia unarmed. No strap-like epipods on third maxilliped to fourth pereopods. Appendices internae on second and fourth pereopods simple, slender, without coupling hooks, those of fourth and fifth pleopods normally developed, with coupling hooks.
