Promachoteuthis sloani is a species of squid from the northern Atlantic Ocean. It is known from only three specimens and very little is understood of its biology.[1] P. sloani is characterised by several morphological features: nuchal fusion is absent between the head and mantle, the arms generally bear 3–4 series of suckers, and papillae are present on the tentacles.[2]
The holotype is an immature female of 58 mm mantle length (ML) in near-perfect condition. It was caught by R/V G.O. SARS in 2004 at 53°05′N 36°46′W / 53.083°N 36.767°W. The paratype, also an immature female, is larger at 102 mm ML. It was caught by R/V Walther Herwig in 1973 at 46°00′N 15°49′W / 46.000°N 15.817°W. Both were trawled in nets that fished to depths greater than 2,650 m.[2]
