Houndfish (Tylosurus Crocodilus) Fish Description

Where did the Houndfish get its name? It certainly doesn’t look like a hound! The Houndfish is a serpentine fish. It’s quite long and has a long snout in the shape of a needle. Hence, its other name – the Crocodile Needlefish. It has a stout body that appears cylindrical and a shorter head than most needlefishes. Its snout however makes up for the length.

Color-wise, the Houndfish is dark blue with silver-white sides. The rest of them is a plain white color. The Houndfish also has a distinct feature. It has a keel on its caudal peduncle and its tail fin is deeply forked. Its dorsal fin is much closer to the tail fin and runs parallel to the anal fin. 

While young, the Houndfish’s’ teeth usually are pointing forward whereas others have them pointing straight.

Houndfishes, since they like remaining near the surface, usually feast on small fishes. They like feasting on small flying fishes since they’re quite the magnificent leapers themselves. Their fish of choice however is anchovy. 

Houndfishes are considered the biggest in the Belonidae family. They can grow up to a whopping 5ft and weigh up to 14 lbs. However, their average weight is around 10 lbs.
