From the worst-written Wikipedia article I’ve ever seen:
Sepioloidea lineolata or more commonly known as the striped pyjama squid or the striped dumpling squid is a type of bottletail squid, that inhabits the Indo-Pacific Oceans of Australia. Although it is not quite a cuttlefish, as it does not have a cuttlebone, it is otherwise exactly the same as cuttlefish. Therefore it is a sepioid, not a real cuttlefish. However, it is usually referred to as a cuttlefish for public simplification. It is not a squid either.
