The slim bodied barracudas, with their long, pointed heads, somewhat resemble the pikes in general appearance. But they are distinguishable from the latter at a glance by having two dorsal fins. The lower jaw projects beyond the upper, and both jaws are studded with large pointed teeth of unequal sizes. The gill covers are scaly, and there is a well-developed lateral line. The first dorsal is spiny, the second soft-rayed. The anal is roughly opposite the second dorsal, the ventrals opposite the first dorsal, the pectorals short, the caudal forked.
