Abstract

Like many cephalopods, females of the squid species Loligo pealei have a pair of accessory nidamental glands (ANG) that harbor a dense bacterial community (Bloodgood, 1977). The ANG is closely associated with the nidamental gland, which produces capsule-like membranes surrounding the eggs (Fig. 1). Because of its close association with the nidamental gland and the oviduct, the ANG probably plays a role in protecting the eggs by coating them with bacteria (Barbieri et al., 1997; Biggs & Epel., 1991). Recently, identical or very similar bacteria have been found in the ANG and in the egg cases of Loligo pealei (Barbieri et al., unpublished results).
