Fun Copper Rockfish Facts For Kids
Gallery
The copper rockfish (Sebastes caurinus), also known as the copper seaperch, is a type of fish belonging to the family Sebastidae, consisting of rockfish, rock perch, rock cod, and other fishes. The copper rockfish has two different types of color variations depending on the northern and southern location of their populations.
This fish enjoys a long life length of up to 40 years.
The usual habitat for both male and female adults tends to be in the deeper end of sea reefs and near rocks.
However, the choice of habitat for juveniles tends to be a shallow coastal bay, kelp beds, and rocky areas near the sea surface. The unique identification of this fish is that their body is similar to marine rocks.
This feature also helps juvenile fishes and the young to remain protected in shallow water. You may spot the fish on the vast east coast of the Pacific Ocean, and the range tends to be from the Gulf of Alaska to Baja California, Mexico.
This species of fish is also popularly considered gamefish and is caught by pier anglers.

To keep themselves and their young and juveniles protected, the rockfish copper chooses to give birth as well as live the rest of their lives near rocky areas near the coast, which helps them conceal their identity from the rest of the organisms.
They also try creating their homes in the depth of the ocean with rocks, reefs, and dark interiors as a way of camouflaging themselves with their surroundings.
