New England Aquarium Goosefishes in the family Lophiidae have flattened heads and bodies covered in thin skin and are further characterised by the possession of
pelvic fins with the first, spiny
dorsal fin having its origin close to the rear of the head and this fin is supported by between one and three spines. There are 4
pharyngobranchials, the 4th being toothed, and they have a large
pseudobranch. The body has no scales and the
frontal bones of the skull are fused. They have a very wide, flattened head, although
Sladenia has a more rounded head, with well developed teeth. The lower jaw has a fringe of small flaps along its edge and these extend along the head onto the flanks. The second dorsal fin is supported by between 8 and 12 soft rays while the
anal fin contains between 6 and 10 soft rays. Most taxa have 18 or 19 vertebrae but in
Lophius this count is between 26 and 31. The largest species in the family is the angler (
Lophius piscatorius) which has a maximum published
standard length of while the smallest is
