The strap-toothed whale is thought to be relatively common (7), but a lack of information on its global abundance or population trends makes it difficult to assess its conservation status (1) (3). However, beaked whales appear to have naturally quite low populations, meaning even low-level threats can have unsustainable impacts (1). The strap-toothed whale is not directly hunted, although some bycatch in gillnets and longline fisheries is likely (1) (5) (12) (14). Other threats may include noise pollution, which has been linked to mass strandings of other beaked whale species, as well as chemical pollution, ingestion of plastic waste, and ocean warming as a result of climate change (1) (3) (12) (14). The strap-toothed whale's preference for deep waters may have helped protect it in the past from the threats facing more coastal species (3), but as fisheries expand into deeper waters the species may face increasing competition for its squid prey, and an increased threat from entanglement in nets (3) (12).
