Elopiformes have an upturned mouth with a long gular plate between the lower jaws. Scales are cycloid and particularly large and thick in tarpon (Megalops spp.), making phlebotomy and injections difficult (Helfman et al. 2009). The swim bladder is lung‐like and tarpon are facultative air‐breathers. Tarpon have additional cranial outgrowths of the swim bladder that contact the auditory region and are partially enclosed in bony bullae, which presumably improve their sense of hearing (Fletcher and Crawford 2001).
