Colossendeis is a genus of sea spider (class Pycnogonida) belonging to the family Colossendeidae.[1] Phylogenetic analysis based on molecular data indicates that this genus is paraphyletic with respect to the genera Decolopoda and Dodecolopoda, which are found to be nested within the genus Colossendeis in a phylogenetic tree.[2]

The genus Colossendeis includes the largest pycnogonids, with leg spans of about 40–50 centimetres (16–20 in). These sea spiders can be found in deep-sea.[3]

The genus contains bioluminescent species.[4]
