Answer 2

As you've probably guessed from all the answers here, orcas are definitely not invertebrates. Invertebrates do not have a vertebral columns (also known as backbones). Orcas (aka killer whales) are indeed vertebrates and are actually dolphins (already stated earlier) and therefore mammals just like us.
What is interesting, though is that most of life on earth technically falls under the invertebrate category and vertebrates make up only a very small portion of animals on the planet.
With regards to animals, invertebrates are either squishy or crunchy (they have hydrostatic skeletons made of water or exoskeletons) and vertebrates have an internal skeletons with a backbone that normally contains the spinal cord.

Answer 3

The Orca or Killer Whale (Orcinus orca), less commonly, Blackfish or Seawolf, is the largest species of the oceanic dolphin family (Delphinidae). It is found in all the world's oceans, from the frigid Arctic and Antarctic regions to warm, tropical seas.

Orcas are versatile and opportunistic predators. Some populations feed mostly on fish, and other populations hunt marine mammals, including sea lions, seals, and even large whales. There are up to five distinct Orca types, some of which may be separate subspecies or even species. Orcas are highly social; some populations are composed of matrilineal family groups which are the most stable of any animal species.[1] The sophisticated social behaviour, hunting techniques, and vocal behaviour of Orcas have been described as manifestations of culture.

Although Orcas are not an endangered species, some local populations are considered threatened or endangered due to pollution, depletion of prey species, conflicts with fishing activities and vessels, habitat loss, and whaling. Wild Orcas are usually not considered a threat to humans.[2] There have, however, been isolated reports of captive Orcas attacking their handlers at marine theme parks

Answer 4

Orcas - also known as killer whales are actually a type of dolphin.
So they are definitely not invertebrates.
Just read about them in an excellent book by Peter Mathiesson - forgotten the title but it was something like To The End Of The Earth - an account of two journeys to Antarctica.

Answer 5

No. If you need a source, wiki it and while you're at it wiki the word invertebrate and see why you should know the definition to the words you use in your questions :P

Answer 6

No

Orcas; killer whales are swimming mammals and ALL mammals have a spine and are vertebrates.

Invertebrate means no spine like a slug, or an animal with an exoskeleton like a crab.

Answer 7

Ya they're the largest member of the sea cucumber family.

Answer 8

Good old education system.....such a joke....
