Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'snubfin' literally as "курносый плавник". It is a fixed zoological term. Use the established name "австралийский курносый дельфин" or the scientific name.
- Do not confuse with the similar "Иравадийский дельфин" (Irrawaddy dolphin).
Common Mistakes
- Incorrect: 'Australian snub-fin dolphin' (hyphenation is variable but typically solid as a premodifier).
- Incorrect: Using it as a common noun without the capital 'A' for 'Australian'.
- Confusing it with the Indo-Pacific humpback dolphin.

Frequently Asked Questions
No. They are separate species in the same genus (Orcaella). The Australian snubfin dolphin (Orcaella heinsohni) was recognized as distinct from the Irrawaddy dolphin (Orcaella brevirostris) in 2005.
The name refers to its small, rounded, and seemingly 'snubbed' or stubby dorsal fin, a distinguishing feature compared to more triangular fins of other dolphins.
They are found in shallow, coastal waters, river mouths, and estuaries of northern Australia, from the Kimberley region in Western Australia to Papua New Guinea. Seeing them requires specific eco-tours in these remote areas.
Yes, they are listed as Vulnerable. Threats include habitat degradation, coastal development, pollution, entanglement in fishing gear, and boat strikes.
