Bobtail squid (order Sepiolida) [1] are a group of cephalopods closely related to cuttlefish. Bobtail squid tend to have a rounder mantle than cuttlefish and have no cuttlebone . They have eight suckered arms and two tentacles and are generally quite small (typical male mantle length being between 1 and 8 cm (0.39 and 3.15 in)).
Like other bobtail squid, southern dumpling squid have a light organ fuelled by symbiotic bioluminescent bacteria. The light organ, which is butterfly-shaped, is situated in the mantle cavity and is used to cancel out the bobtail squid's silhouette. There are large semi-circular fins on the rear half of the mantle.
