Mating and spermatophore placement in the onychoteuthid squid Moroteuthis ingens

Males of the onychoteuthid squid Moroteuthis ingens implant spermatophores directly into a variety of internal and external tissues of the female, based on the examination of 14 individuals collected south of Tasmania, Australia. Furthermore, the capture of a pair of mating individuals suggests that 'jaw locking' reminiscent of cichlid fish may be a behaviour associated with courtship and mating.
