About Sepioloidea lineolata (Quoy & Gaimard, 1832)
Sepioloidea lineolata, commonly called the striped pyjama squid or striped dumpling squid, is a species of bottletail squid that lives in the Indo-Pacific Oceans surrounding Australia. This species inhabits the seafloor, and often hides in sand. Fully mature striped pyjama squid reach only 7 to 8 centimetres (2.8 to 3.1 inches) in length, while newly hatched individuals can be smaller than 10 millimetres (0.39 inches). Striped pyjama squid reproduce sexually. To mate, a male grasps the female and positions them so they are aligned head-to-head. The male then inserts a spermatophore, a packet of sperm, close to the location where the female stores sperm until she is ready to lay eggs. If a male detects sperm from a previous male inside the female, he can remove that existing sperm using a specialized spoon-shaped arm. Like many other species in the order Sepiida, males typically die after mating. Females lay their eggs in batches or clumps under coral on the seafloor, shortly after mating.
