Snubfin Dolphin

Threatened Status:

  • Vulnerable (IUCN – Global Status);
  • No status listed in EPBC due to data deficiency (Australia);
  • Vulnerable (Nature Conservation Act 1992 – QLD)

Location:

Northern Australia – QLD, NT & WA.

Identified as a new species in 2005, the snubfin dolphin is Australia’s only native dolphin, which means it is unique and endemic to our waters.

Snubfin dolphins live in small isolated groups along Australia’s northern coastline, from the Kimberley to Gladstone. Numbers of snubfin dolphins are so low that the species is considered vulnerable to extinction both globally and in Queensland. The main threats to snubfin dolphins are drowning in fishing nets and habitat destruction. Snubfin dolphins live in riverine, estuarine coastal waters and are recognised by their distinctive rounded head and lack of a beak, unlike other dolphins species.

Threats to Snubfin Dolphins

One of the main threats to snubfin dolphins is incidental capture from netting, especially gill nets set to catch fish such as barramundi and threadfins in QLD. Other threats include habitat destruction (particularly mangroves and seagrass), pollution, boat strike, and incidental capture in shark control programs.

Snubfin dolphins have low population growth rates, which means they are especially vulnerable to decline. Most of their remaining populations are not considered viable for the long-term, with even the loss of one individual dolphin from human activities likely to push a regional population into irreversible decline.

In October 2017, two snubfin dolphins drowned in legally set nets in the Great Barrier Reef Marine Park. Four dugongs were also killed around this time (one of these deaths by gillnet drowning), so AMCS and other conservationists called for netting bans in high value dugong, dolphin and turtle habitats. The two snubfin dolphin deaths and confirmed dugong death were reported appropriately by the commercial fishers operating the gillnets.

Gillnets are invisible walls of death for some of Queensland’s precious marine wildlife. We need to move away from these deadly fishing methods towards more sustainable fishing, particularly within the Reef’s World Heritage waters.

What is AMCS doing about this issue?

AMCS is calling on all Queensland parties to end gillnetting in high conservation value areas. As a particular priority, gillnets should be removed from the marine park waters north of Cooktown. This would protect Queensland’s snubfin dolphins, dugongs and turtles, as well as enhance the World Heritage values of our Great Barrier Reef.
