starts withAs no individuals have been identified for over 80 years, C. obsoletus may be extinct. Like other members of the C. porosus subgroup, C. obsoletus likely had limited fecundity and lived in shallow waters that are easily accessed by fishermen, both of which put it at heavy risk of extinction from overfishing. However, the rediscovery of the Borneo shark (C. borneensis) in 2004 after a long period of no sightings has kept hopes for its possible survival. But in 2020, the IUCN Red List declared the lost shark to be Critically Endangered or Possibly Extinct.
