To let out a chuckle or giggle is to laugh: people laugh when something is funny. To chortle, cackle, guffaw, or titter is to laugh. The job of a comedian is to make people laugh. Often people laugh at things that aren't supposed to be funny, and people also laugh to be polite. If something is silly, you can say That's a laugh!.
Baleen whales are the largest of all cetaceans, representing 11 distinct species across four families. These families include the right whales, pygmy right whales, gray whales and rorqual whales.
To sum things up: dolphins, porpoises and whales are all whales too. Orcas however, more commonly known as killer whales (think âFree Willyâ), are dolphins too. I know what youâre thinking, if all whales are whales, and if dolphins and porpoises are whales, then maybe all whales are dolphins too.
