Breeding
Sharks and rays grow slowly and have few young. A fishery that treats them as bycatch can empty a coastal form.
In crisis
When threatened the whitefin swellshark can inflate itself with water or air to increase its size. As of 2019 The International Union for Conservation of Nature (IUCN) has assessed this species as Critically Endangered due to the significant decline of the population.
