The thorny whiplash squid, known as Asperoteuthis acanthoderma is a large species of squid belonging to the family Chiroteuthidae. It is characterised by the tiny, pointed tubercules present on its skin and a Y-shaped groove in the funnel locking apparatus.[4]

The largest recorded specimen measured 78 cm (2.56 ft) in mantle length (ML), although its original total length is unknown as it was missing the very delicate feeding tentacles.[5] A smaller specimen, 45 cm (1.48 ft) ML, had tentacles 12 times the length of its mantle, giving a total length of almost 5.5 m (18 ft).[6] This makes A. acanthoderma one of the longest known cephalopods.

The

Okinawa,[6] and Hawaii.[8]

The first known specimen from the

Key West, Florida on 20 February 2007.[9] It measured 73 cm (2.40 ft) ML and is thought to have been 4.9 to 7.3 m (16 to 24 ft) long when intact.[10] Although an incomplete specimen, missing most of its tentacles, it weighed 6 kg (13 lb) and measured 2 m (6.6 ft) in total length.[9]

In 2007,

teuthologist Richard E. Young stated that "probably fewer than 10" specimens of A. acanthoderma had ever been reported.[10] However, since 2006 there has been an influx of new specimens from the Caribbean Basin and Atlantic.[1] Four specimens were recorded between 2006 and 2007 (two from the Florida Keys, one off Grand Cayman, and one off Little Cayman).[1][11] This was followed by another specimen from Little Cayman in May 2008 and another from Grand Cayman in September 2009.[1][12] A large specimen around 2 m (6.6 ft) long was found floating at the surface off the Cayman Islands in 2013.[13] It was transported to the University of South Florida St. Petersburg on a Royal Caribbean cruise and later transferred to the National Museum of Natural History in Washington, D.C.[13][14]

This squid is known to be eaten by the

wandering albatross.[15]
