Rissoides desmaresti is a species of mantis shrimp native to the eastern Atlantic Ocean and Mediterranean Sea.
Distribution
[edit]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-hectare (62-acre) 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 sheltered nature of the area.[5]
Description
[edit]R. desmaresti has a dorso-ventrally flattened body and may reach a size of 70 millimetres (2.8 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 metres (130 ft).[2]
Etymology
[edit]The specific epithet "desmaresti" commemorates Anselme Gaëtan Desmarest,[6] while the generic name Rissoides commemorates Antoine Risso.[7]
