Bottletail Squid [Sepiadarium]

Description

Sepiadarium is a genus within the family Sepiadariidae, known for its small, compact body and characteristic bottle-like shape. These squid are distinguished by their short, broad mantle and the presence of eight arms and two tentacles, with the latter often equipped with an enlarged club. Members of this genus inhabit sandy and muddy substrates in tropical and subtropical oceans, where they bury themselves during the day and emerge at night to feed. Their diet primarily consists of small fish, crustaceans, and other invertebrates. Sepiadarium species are notable for their ability to rapidly change color for camouflage and communication, utilizing a complex system of pigment cells known as chromatophores.
