Colossendeidae

Colossendeis Decolopoda Dodecolopoda Hedgpethia Pentacolossendeis Rhopalorhynchus Colossendeidae is a family of sea spiders (class Pycnogonida).

[3] Most colossendeids can grow to giant sizes as adults, far larger than any other sea spiders.

[8][9] Colossendeids typically have no chelifores, except in the extra-legged species which have robust pincers and 2-segmented scapes.

[8][6] The palps and ovigers are present in both males and females, they are elongated with basal processes located very close to each other.

[10] Each oviger ends in a strong terminal claw and compound spines arranged in fields or rows on a well formed strigilis (hook-like distal segments).
