[1] The silurid
The silurid (silurus glanis), an (up to 3 metres long) freshwater fish. Aristot. Hist. an. 8(9),37,691 a20-b2 describes the care of the brood of the glánis, whose name was passed on to Thomas of Cantimpré (glamanez monstrum [1] 6,26) and Albertus Magnus (garcanez, animal. 24,35 [2]) via the Arabian-Latin translation of Michael Scotus as glanieuz without real knowledge of the animal. A connection to evil demons was ascribed to it, perhaps due to its supposed attacks on fishing nets [3. 1 § 458].
