Orcas are apex predators with a diverse diet; different populations specialize on prey including bony fish, sharks, rays, and marine mammals such as seals, dolphins, and whales.

Are orcas social animals?

Yes; orcas are highly social and some populations form stable matrilineal family groups (pods) with group-specific hunting and vocal traditions.

Are orcas dangerous to humans?

Orcas rarely pose a threat to humans and no fatal attack has been recorded in the wild, though captive orcas have injured or killed handlers in marine parks.

Have any orca populations been specially protected?

Yes; for example, the southern resident orcas were added to the U.S. Endangered Species list in late 2005.

Why are some orca populations threatened?

Local populations face threats including prey depletion, habitat loss, pollution by PCBs, captures for marine parks, and conflicts with fisheries.

Do orcas occur everywhere?

Orcas are cosmopolitan and occur from polar to tropical seas but are more commonly documented in temperate or cooler coastal waters.

Are there different types of orcas?

Scientists have proposed dividing the global population into races, subspecies, or possibly even species, and the most studied groups include resident, transient, and offshore types off western North America.

Where to See Killer Whale (Orca) While Diving

Q: What is the conservation status of orcas?

The IUCN lists the orca as Data Deficient because multiple orca types may represent distinct species; some local populations are threatened or endangered.

The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is recognizable by its distinct pigmentation: mostly black on top, white on the bottom, and with white eye patches. A cosmopolitan species, orcas inhabit a wide range of marine environments from Arctic to Antarctic regions and tropical seas, and are more commonly documented in temperate or cooler coastal waters. Scientists have proposed dividing the global population into races, subspecies, or possibly even separate species. Orcas are apex predators with a diverse diet; individual populations often specialize on particular prey types. They are highly social, with some populations forming stable matrilineal family groups (pods). Orcas employ sophisticated hunting techniques and vocal behaviors that can be unique to specific groups and passed down through generations—traits considered manifestations of animal culture.

The global assessment is Data Deficient because multiple orca types may represent distinct species; some local populations are threatened or endangered due to prey depletion, habitat loss, pollution (PCBs), captures for marine parks, and fisheries conflicts.

Orcas are cosmopolitan, inhabiting a wide range of marine environments from Arctic to Antarctic regions and tropical seas, and are more commonly documented in temperate or cooler coastal waters.

The strongest linked planning options currently surface around destinations such as Mercury Islands (Coromandel Peninsula), Hurghada (Giftun and Abu Nuhas) and countries such as New Zealand, Germany, Argentina for divers building trips around killer whale (orca)s.
