Description

Eulagisca gigantea can grow to a length of 20 cm (8 in) and a width of 10 cm (4 in). It is dorso-ventrally flattened and has 40 segments with 15 pairs of elytra. The prostomium is oval and the back part is concealed by a nuchal fold.[2] The lateral antennae are inserted terminally on the anterior margin of the prostomium. The notochaetae are about as thick as the neurochaetae, but bidentate neurochaetae absent. The eversible proboscis bears a pair of large jaws and is about a quarter of the length of the whole organism. It is a greyish-brown colour and without patterning.[3]
