Great Barracuda

Family Sphyraenidae

Description: gray, with a greenish cast above, whitish below; many irregular, small black blotches on lower side; 18 to 22 diagonal dark bars on upper side (not always evident); caudal fin dark with white tips; 75 to 87 lateral line scales; no fleshy tip on jaw

Remarks: most attacks on people have occurred when they were wading or swimming in turbid water while wearing bright objects, attempting to spear a barracuda, or carrying speared fish; flesh of smaller fish apparently not poisonous, but larger fish sometimes very toxic due to ciguatera; no safe, reliable way of recognizing toxic fish
