Summary

Description

The great spider crab is reddish-brown with a pear-shaped carapace, up to 10 cm long and 8 cm wide. At the anterior end the rostrum projects between the eyes and is split into 2 tapering parts that touch at their tips. The first pair of abdominal limbs, or pleopods, bear pincers and are shorter and stouter than pairs 2-5, which are long, slender and spider-like. The carapace has a few large tubercles and may be covered with encrusting invertebrates.

Recorded distribution in Britain and Ireland

Found around all British coasts, but less common in the south and west.

Global distribution

A northern species found around Spitzbergen, Iceland and Norway, also Greenland and north America, reaching its southern limit in the English Channel.

Habitat

Hyas araneus is found on hard and sandy substrates, among rocks and seaweed on the lower shore and sublittorally to a depth of about 50 m.
