Pigfish facts are interesting to read.

The pigfish (Orthopristis chrysoptera) is an oceanic fish, native to the Western Atlantic Ocean.

They belong to the Haemulidae family and the Actinopterygii class. The primary habitat of this fish is the Nearctic zones of the Western Atlantic Ocean, but the range of this species also includes the north shore of Massachusetts, Florida, Bermuda, Cuba, the Yucatan Peninsula, and the Gulf of Mexico.

Due to their vast range and continuously being caught by humans in large quantities, it is next to impossible to get the exact statistics of their population, but they are listed as a Least Concern species by the International Union For Conservation of Nature (IUCN) Red List.

Pigfish have an oval body covered in bluish-gray scales and a silver-colored underbody. Their dorsal fins are similar to pinfish fins. They use the spawning method to reproduce, and their breeding season starts in spring. They are nocturnal predators that survive on a carnivorous diet. Their diet includes invertebrates, smaller fish, and crustaceans.

To learn more, we have collected a set of interesting facts about pigfish for you to read. You can also learn more about other fascinating wild animals and fish by reading about the toadfish and blobfish here on Kidadl.
