| Like pangolins, aardvarks have a long, protrusile tongue and a gizzard-like stomach. |
| Most lampridiforms have highly protrusile jaws in which depression of the lower jaw dislocates the maxilla of the upper, so that it moves forward bodily, carrying the premaxilla with it. |
| The jaws of many atheriniforms are protrusile, but the structural modifications by which this is achieved are quite different from those of typical acanthopterygians. |
| This slow, stealthy mode of swimming, coupled with their highly protrusile mouths, adapts them for stalking and engulfing prey. |
