Striped Pyjama Squid

Sepioloidea lineolata

The Striped Pyjama Squid, also known as the Striped Squid, is a species of cephalopod belonging to the genus Sepiadarium.

 It is named for its distinctive stripes that run vertically along its body and legs, giving it a distinctive “pajama-like” appearance. These stripes range in color from yellow to brown and are used as a form of camouflage.

In terms of size, the Striped Pyjama Squid grows to an average length of 20-30 cm (8-12 inches) with a maximum length of 40 cm (16 inches). It is considered a small species of squid, but its distinctive markings make it easily recognizable.

The Striped Pyjama Squid is primarily found in the tropical waters of the western Pacific Ocean, from the Philippines to the coast of Australia. They prefer to inhabit shallow waters near the shore, including coral reefs and mangrove swamps. 

They are also known to inhabit deeper waters, down to a depth of about 200 meters (656 feet).

The Striped Pyjama Squid is a carnivore, feeding on small crustaceans, fish, and other squid. It uses its two tentacles to grasp its prey and then uses its beak-like mouth to bite and tear off pieces to consume.


The Striped Pyjama Squid is primarily a solitary species, only coming together to mate. It is active during the night and remains concealed during the day, either hiding in crevices or burying itself in the sand. 

It is capable of rapidly changing its color and patterns to blend into its surroundings, making it difficult for predators to detect.


The scientific name for the Striped Pyjama Squid is Sepioloidea lineolata. It belongs to the family Sepiadariidae and is a type of cuttlefish. Cuttlefish, like all cephalopods, have a unique internal shell called a cuttlebone, which helps them control their buoyancy in the water.

The Striped Pyjama Squid has not been evaluated by the International Union for Conservation of Nature (IUCN), but is not considered threatened or endangered. 

However, as with many marine species, its populations may be impacted by overfishing, pollution, and the destruction of its habitat. It is important to monitor and protect the habitat of this species to ensure its survival in the future.
