Summary

[edit]
Description
Français :

L'araignée de mer atlantique (Maja brachydactyla) est un crustacé. On la rencontre dans les eaux de la Mer du Nord jusqu'aux Canaries, sur les fonds sableux ou rocheux, entre la surface et 50 m de fond. Ici, il s'agit d'un individu mâle, photographié en rade de Brest sur un fond de maërl (accumulation d'algues corallinacées fréquente en Bretagne).

Sa carapace, fortement bombée et arrondie, peut mesurer jusqu'à 25 cm de long et 18 cm de large. Ses pattes, à la pilosité importante, sont longues et fines. A noter que, contrairement aux autres crustacés, l'araignée de mer a une mue terminale, qui a pour conséquence de stopper net sa croissance.

Sa pêche fait l'objet d'une réglementation : voir Convention de Berne (relative à la conservation de la vie sauvage et du milieu naturel en Europe) : Annexe III – Espèces protégées.

English:

The Atlantic spider crab ( Maja brachydactyla ) is a crustacean. It is found in the waters of the North Sea to the Canaries, on sandy or rocky bottoms, between the surface and 50 m deep. Here, it is a male individual, photographed in the harbor of Brest on a bottom of maërl (accumulation of coralline algae common in Brittany).

Its shell, strongly domed and rounded, can measure up to 25 cm long and 18 cm wide. Its legs, with significant hairiness, are long and thin. Note that, unlike other crustaceans, the spider crab has a terminal moult, which has the consequence of stopping its growth abruptly.

Its fishing is subject to regulation: see Berne Convention (relating to the conservation of wildlife and natural habitats in Europe): Annex III – Protected species .
