No information is available on mating in Mesoplodon perrini.
There is currently little information available regarding reproductive habits of Mesoplodon perrini or other ziphiids. The two adult type specimens were both sexually mature, and an analysis of the teeth indicated an approximate age of 9 years for both of them.
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); viviparous
Little is known about parental investment in Mesoplodon perrini. However, the 2.1 meter type specimen had a fringed tongue, which indicates that it was not yet weaned when it died. Researchers suspect that it was the calf of the adult female type specimen, and that it was still dependent on her when she was stranded. Like all other whales, young are able to swim soon after birth.
Parental Investment: precocial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female); pre-independence (Provisioning: Female, Protecting: Female)
