Pyroteuthidae (the fire squids) is a family of squids. The family comprises two genera. Species are diurnally mesopelagic, migrating into surface waters during the night. The family is characterised by the tentacles, which have a permanent constriction and bend near the base; and photophores occurring on the tentacles, eyeballs, and viscera. Members reach mantle lengths of 23–50 mm. Paralarvae of the family are common around the Hawaiian Islands, with up to 17% of collected specimens in the area belonging to Pyroteuthidae.[2]

Pyroteuthidae Pfeffer, 1912 è una famiglia di molluschi cefalopodi appartenenti all'ordine Oegopsida[1].

Descrizione

Il mantello non supera i 5 cm di lunghezza e non presenta fotofori, assenti anche sulle braccia ma presenti su tentacoli e organi[2]. I fotofori hanno diverse funzioni, tra cui confondere i predatori rendendo più difficile individuare l'animale da sotto[3].
La durata della vita è molto breve, per esempio gli esemplari di Pyroteuthis margaritifera non superano i 78 giorni di vita[3].

Tassonomia

Comprende 2 generi[1] che precedentemente erano classificati nella famiglia Enoploteuthidae[4]. Fino al 1988 questa famiglia era infatti considerata sottofamiglia di Enoploteuthidae[3].

Distribuzione e habitat

Sono specie comuni, diffuse in tutti gli oceani[2][5]. Gli esemplari adulti vivono più in profondità dei giovani, ma durante la notte ritornano più vicini alla superficie[2].
