Brown above and cream below, these long, slender creatures are well-equipped for their aquatic habits. Its bones show osteosclerosis, increasing their density to reduce buoyancy. This otter differs from the North American river otter by its shorter neck, broader visage, the greater space between the ears and its longer tail.〔Godman, John Davidson (1836) ''American Natural History'', Hogan & Thompson.〕 However, the European otter is the only otter in its range, so it cannot be confused for any other animal. Normally, this species is 57 to 95 cm (23–37 in) long, not counting a tail of 35–45 cm (14–18 in). The female is shorter than the male. The otter's average body weight is 7 to 12 kg (15.4–26.4 lbs), although occasionally a large old male may reach up to 17 kg (37 lbs).〔(European Otter ). theanimalfiles.com〕〔(European Otter ). purpleopurple.com〕 The record-sized specimen, reported by a reliable source but not verified, weighed over 24 kg (53 lbs).〔Wood, Gerald L.
