It burrows into soft mud or sand, and when covered with water extends its tentacles to feed on tiny particles of detritus.

E. neozelanica is found in New Zealand, in intertidal areas such as harbour mouths or rock pools where silt and mud accumulates.

[1] Being small and so similar in colour to the substrate it lives in, E. neozelanica is a cryptic species most often found when sand or mud is passed through a fine sieve.

[4] The scapus or body column is wrinkly and covered with a rough cuticle that can be brown, grey, or orange in colour, with a narrow neck at the top connecting it to the capitulum or oral end.

[4] E. neozelanica has on its capitulum sixteen or more transparent tentacles, usually in two whorls of eight, that are pinkish white to buff yellow or brown in colour.
