[edit] Distribution
R. desmaresti is one of only two species of stomatopod found around the British Isles, and one of twelve species in the Mediterranean [1]. It is relatively common in the Mediterranean, and is found along the European coast as far as the British Isles, although it has not been recorded off the coast of West Africa [2]. Around Great Britain, there have been a few observations from the English Channel and North Wales [3][4], but the only place where significant numbers are known to occur is on a 25–ha site east of Saint Tudwal's Islands in Tremadog Bay [5]. Its occurrence there may be related to warm currents coming from the Bay of Biscay and the sheletered nature of the area [5].
[edit] Description
R. desmaresti has a dorso-ventrally flattened body and may reach a size of 70 mm (2¾ in). The carapace is small and is only fused to the first two segments of the thorax [2]. R. demsaresti is distinguished from the other British species, Platysquilla eusebia, by the number of spines on the last segment of the raptorial claw; R. desmaresti has five spines, while P. eusebia has a dozen or more [4]. It lives in burrows below from the subtidal zone down to depths of around 40 m [2].
[edit] Etymology
The specific epithet "desmaresti" commemorates Anselme Gaëtan Desmarest [6], while the generic name Rissoides commemorates Antoine Risso [7].
