Did you know that giant javelin-like fish impale people occasionally?
From Peterson's Field Guide to Atlantic Coast Fishes:
Needlefishes: Family Belonidae
These fishes are easily startled, and become disoriented around artificial light at night; They may skip along the surface or leap from the water and can become "living javelins." The Houndfish is especially dangerous in this regard...
Houndfish Tylosurus Crocodilus
Size: up to 5 feet and more than 10 pounds
Serious wounds and some fatalities have occurred when leaping Houndfish have accidentally impaled fishermen.
