Bréchet

A distinctive bulge or ridge at the base of the tail of whales and dolphins, just in front of the flukes [1].

A term for the longitudinal ridge or plate of bone on the underside of a bird's sternum, or breastbone, sometimes called the carina [2]. The keel of the breastbone separates two masses of muscles in the breast and gives them a strong attachment [2]. Ratite birds (the flightless ostrich, rhea, cassowary, emu, and kiwi) lack a keel and have a flat sternum, or breastbone [2].

Carinate means shaped like the keel or prow of a ship. The term is used wih birds with a keeled breastbones [2].
