The 1953 specimen was described as being 76 cm (2.4 ft) long with thick reddish brown skin, bulging eyes and gills. It was also described as having hind legs with five-toed horseshoe-shaped feet with concave arches – which appeared to be suited for bipedal locomotion – but no forelimbs. Its remains were cremated after a cursory inspection by zoologists who said that it posed no danger to the public. The 1954 specimen was described as being similar to the first but much larger, being 120 cm (4 ft) long and weighing approximately 11.3 kg (25 lb). It was sufficiently fresh for its eyes, nostrils and teeth to be studied though no official explanation was given at the time as to what it was or what happened to the carcass.
The carcass is now considered to have actually been a monkfish, a close relative of anglerfish with an extremely similar body shape to the photos of the monster.
