Acoelomate, bilaterally symmetrical and with differentiated cuticle marine metazoan. Compound cilia for filter feeding working as a downstream-collecting system.
Inhabits the mouth appendages of Norway lobsters (Nephrops norvegicus) with carapace lengths of greater than 3.5 mm. Commensal with lobster. Feeding stages alternating with brief, non-feeding, free-swimming stages. Sessile, solitary feeding stages with multiciliated cells in the gut, anus just behind a ciliated mouth ring, and internal budding with extensive regeneration of feeding apparatus (Ref. 376).
