(Sars, 1846)

Pneumatophore [A.elegans-top ]: small, ovoid, usually with red-pigmented cap.
Nectophore [Agalma elegans ]: with large truncated lateral processes which surround the nectosomal stem. Latero-vertical ridge runs perpendicularly up from the infra-lateral ridge and delimits a triangular facet apical ridge and runs along side of nectophore in its distal half. Bracts: thin and leaf-like, ending in three small projections. The siphonosomal stem is highly contractile.
Juveniles [A.elegans-juv ]: the post-larva, or Athorybia stage, bears 4-6 small, thick triangular larval bracts with serrated edge below which is a single gastrozooid.

Pneumatophore with red-pigmented cap.

Nectophore: up to 7 mm in length.
Post-larva is usually less than 4 mm in length.

Depth range
In the W Atlantic known from deeper waters.

Distribution in the North Sea
Mainly known from the northern North Sea in the W English Channel; possibly in the southern North Sea.

World distribution
Cosmopolitan in the World’s oceans, but records are infrequent. Its presence in shallower waters probably is associated with the incursions of oceanic waters on to the continental Shelf.
