Using the remotely operated vehicle Deep Discoverer, we observed a large stylodactylid shrimp resting on a sedimented sea floor at 4826 m in the Marianas Trench Marine National Monument. The shrimp was not collected but most closely resembled Bathystylodactylus bathyalis, known previously only from a single broken specimen. Video footage shows the shrimp facing into the current and extending it...

In situ preservation of mud shrimps of the family Callianassidae (Decapoda: Axiidea) has rarely been noted in the fossil record. The present contribution reports body fossils of four members of the family (“Callianassa” almerai, “C.” pseudorakosensis, “C.” sp. 1 and “C.” sp. 2) which are apparently preserved within their burrows, all from middle Miocene deposits of Austria, Slovakia and Hungary...

An unusual species of the genus Periclimenaeus Borradaile, 1915 (Crustacea: Decapoda: Palaemonidae Pontoniinae) from Heron Island, Queensland, Australia, collected by Dr Niel Bruce in 1979, is described and illustrated. Periclimenaeus denticulodigitus sp. nov., an ascidian associate was collected from coral reef at 7.0 m and presents some interesting new features. It increases to 17 the number ...

A previously undescribed fauna of primitive brachyurans of the family Prosopidae is reported from sponge bioherms in eastern Romania. One new species, Cycloprosopon dobrogea, and several other forms, constitute the brachyuran fauna. The sponge bioherms, which attain a height of 30 meters, have yielded an abundant, but not overly diverse, array of benthic invertebrates. Some of the brachyuran sp...

This study reports a primer set for amplifying a partial fragment of about 610 bp in the fast mutating mitochondrial control region in shrimps of the genus Penaeus (Decapoda: Penaeidae). The utility of this amplified fragment for studying population differentiation and structuring, compared with more conservative mitochondrial genes (16S rRNA and COI), was explored in P. merguiensis populations...

Henri Filhol authored thirteen publications that established new names for decapod crustaceans in 1884 and 1885. The accurate dates of these publications are determined utilising notices of Filhol's publications in contemporary journals and library date-stamps. A checklist of the names for the Decapoda established by Filhol and their current identities is presented. Labophrys Filhol, 1885, and ...

When the swimmerets of decapods beat, they do so because the muscles of each swimmeret are driven by a series of periodic bursts of impulses in its motor neurones. We investigated the effects of proprioceptive feedback on the period of this motor pattern by interfering with the movement of particular swimmerets. In different experiments, we observed three different kinds of results during inter...

A survey was carried out on the prevalence of bacteria and ciliate protozoan of Pellaells indiclls obtained from Ennore estuary, Chennai (Madras), India from November 1989 to July 1992. The study r~vealed the occurrence of Vibrio parahaemolyticus, V. VUlllijiCUS, V. harvey;, V. allguillarum, V. damsela, Pseudomollas sp., P. aemgillo.\'{/ and a tilamentous bacterium Leucothrix sp. This study als...
