Misconceptions
The name 'Grypus' has been used in multiple unrelated taxonomic contexts. Most notably, Halichoerus grypus (grey seal) is a completely unrelated marine mammal ; the specific epithet 'grypus' (meaning 'hook-nosed') refers to the seal's profile. This creates potential confusion in literature searches. The Grypus is unrelated to the seal .
