Named after the baleen whale-like bodies of adult females (from the Greek ketos meaning "whale" or "sea monster" and mimos meaning "imitative"), Cetomimidae have large mouths, and their dorsal and anal fins are set far back of the head. All fins lack spines, and the pelvic fins are absent. The fish also lack swim bladders.

[ 83 ] [ 39 ] On three separate occasions in 2019 orcas were recorded to have killed blue whales off the south coast of Western Australia, including an estimated 18–22-meter (59–72 ft) individual.
