How do they reproduce?

While mating with the female Striped Pyjama Squid, the male Striped Pyjama Squid grasps her and does a head-to-head connection with her, connecting to the mantle. He then injects a sperm packet in the mantle cavity, and the female would store this until the time she is all set to lay the eggs and introduce a new life. If the male fish finds the sperm of another male in the female, he can even remove it. This removal is carried out with a special spoon-shaped arm.

Usually, after breeding, the males die. The females lay down eggs in clumps near coral reefs. The young ones born are all set with their black-white stripes on their bodies. The young fishes are all laid at the depths of about 4920-5742 ft (1500-1750 m). As soon as they hatch, the young ones settle down in their new benthic habitats.

Sepiadariidae Fun Facts

What do Sepiadariidaes look like?

This squid of the Sepiolida order is an absolute magician when it comes to camouflage. It can change its appearance and disguise itself according to its surroundings, thus making identification a little difficult. In situations of threat or attack, the Sepioloidea lineolata changes its body tint to purple or dark brown. This creature has eight arms, two long kidney-shaped fins as well as two tentacles for feeding. These tentacles have tiny suckers on them, which have toothed rims. A web usually encircles the bases of its tentacles on both the inside and the outside. Their bodies are very small, and they have rounded shells.

The large eyes of the Striped Pyjama Squid, Sepioloidea lineolata, are located dorsally on their head.

We find these cephalopods cute! Their amazing colors definitely add to this.

In general, cuttlefish use their skins for communication. They have good control over the pigmentation in their skins. They use this pigmentation to flash information, which may be in the form of random splotches or colored spots. This unique technique, along with their swimming postures as well as the waving of their arms and tentacles is used to convey information.

Yes, the Sepioloidea lineolata is both poisonous as well as venomous. These creatures have venom and poison in them. Underneath their bodies, they have glands, which secrete a toxic slime against their predators. This slime has many toxins and proteins. When this toxin is released, the predators get scared and escape, or it gives sufficient time for the squid to make an escape.

We do not believe these little creatures should be moved from their natural habitats and kept as pets!

Did you know...

The two classifications under this species are the Sepiadarium and Sepioloidea genera.

The genus Sepiadarium has five different species under it. These are: Sepiadarium auritum which is spotted mainly in the eastern Indian Ocean, Sepiadarium austrinum, also known as the southern bottletail squid, Sepiadarium gracilis which has been spotted in the South China Sea as well as off the western Philippines, Sepiadarium kochi, also known as the tropical bottletail squid, spotted in the Indo-West waters of Pacific Ocean, and Sepiadarium nipponianum which has been sighted in the western Pacific Ocean.

The genus Sepioloidea has three different groups under it. These are: Sepioloidea lineolata, popular as the striped pyjama squid, this cuttlefish is found in the Indo-Pacific region of Australia, Sepioloidea magna spotted near northern Australia, and Sepioloidea pacifica, known as the Pacific bobtail squid, which is found to the south of Pacific Ocean.

The Striped Pyjama Squid also has a unique inking strategy. This secreted ink comes from two glands, which contain the melanin pigment. When this ink is expelled, it takes the shape of the squid, confusing the predators and temporarily blinding them.

We are not sure if you can add them to your meals menu, but we do not recommend you try them!
