Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'белый наконечник акула'. The correct Russian zoological term is 'длиннокрылая акула' (long-winged shark) or less formally 'белопёрая акула' (white-finned shark).
Common Mistakes
- Incorrectly writing as three words: 'white tip shark'. The standard form is the closed compound 'whitetip shark'.
- Confusing it with the 'reef whitetip shark' (Triaenodon obesus), which is a different, smaller species.

FAQ
Frequently Asked Questions
While not as frequently implicated in attacks as some other species, the oceanic whitetip is a large, powerful predator and has been associated with attacks on shipwreck survivors. It is considered potentially dangerous.
The oceanic whitetip shark (Carcharhinus longimanus) is listed as 'Critically Endangered' in some regions and 'Vulnerable' globally by the IUCN, primarily due to bycatch in commercial fisheries.
It is extremely rare. Their large size, pelagic nature, and specific requirements make them very difficult to keep in captivity.
They are different species. The 'oceanic whitetip' (Carcharhinus longimanus) is large and lives in open water. The 'reef whitetip' or 'whitetip reef shark' (Triaenodon obesus) is smaller, lives around coral reefs, and has a slender body.
