Just to be awkward.. an Orca I drew at the sketchfu website. Simple tools so its a bit blurry. I’m not sure, but I think Orcas (killer whales) may eat Dolphins?

I know they are very intelligent. Often swim in pods (groups) and use various techniques to catch fish. one of their skills is to collaborate in a group to blow thousands of bubbles, their actions create a “bubble net” that enclose a school of fish and then they grab the fish that have been surrounded.

I also know thwy are Mammals and evolved on land before returning to the water, hence they have blow holes to breathe through the tops of their heads. Their front fins are formed adapted like paddles, but the bone structure is similar to that of a hand. I think I remember that they even have vestigial leg bones attached to their pelvises?

Orcas, Dolphins, and other whales are all part of a family of mammals called Cetaceans. They are some of the most intelligent animals on the planet, and humans have almost driven some of them to extinction or actually hunted some of them to extinction. I still think Whaling should be banned.
