A further new species of Periclimenaeus (Crustacea: Pontoniinae) from Heron Island, Queensland, Australia, is described and illustrated. Periclimenaeus colemani sp. nov., an ascidian associate, was collected from coral reef spur and groove zone and increases to 30 the numbers of Periclimenaeus known from Australia and to 17 the number of species known from Heron Island.

Sir, The ingestion of crustacea and mollusca is one of the most frequent causes of food allergy (1). The mollusca phylum includes lamellibranchia (bivalves) and involves the following orders: mytiloida (familia mytilidae: mussels); ostreoida (familia ostreidae: oysters) and veneroida (familia veneridae: clams) (2). Herein we report a study of 11 cases of IgE-mediated urticaria/angioedema caused...

It is now well established that the antennal glands of Crustacea, both marine and fresh water, are concerned with regulation of the ionic composition of body fluids (Robertson, 1957; Shaw, i960; Lockwood, 1962; Potts & Parry, 1964). This activity is considered by some to be the main function of the antennal gland (Webb, 1940; Parry, i960). Because it produces urine and is undoubtedly concerned ...

Haemolymph inorganic osmolyte changes and Na,K-ATPase activities in trichobranchiate and epipodite tissues were examined in the spiny lobster Palinurus elephas gradually acclimated from seawater (SW; 38 ppt, salinity; 1291 mOsmol/l) down to dilute seawater (DSW; 20 ppt, salinity; 679 mOsmol/l). During acclimation to DSW haemolymph was only transiently hypoosmotic, becoming isosmotic to the medi...

Two new species of the deep-sea scavenging genus Cyclocaris (Crustacea: Amphipoda) are described from bathyal and abyssal depths in the North and tropical Atlantic Ocean, bringing the total number of species in the genus to four. An account of all four species is given and an updated key to the genus Cyclocaris is provided.

Megabalanus coccopoma (Darwin, 1854) is a globally invasive species in Balanomorpha (Crustacea). This model organism for studying marine pollution and ecology. However, its mitogenome remains unknown. The sequencing of M. completed the present study. It has 15,098 bp length, including 13 protein-coding genes (PCGs), 2 ribosomal RNAs (rRNAs), 22 transfer (tRNAs), along with putative regulatory a...
