Cabezons come in various color morphs. They can be brown, bronze, reddish, or greenish above, with a whitish or turquoise green belly.

They have a dark and light mottling on the side and a translucent turquoise green lining on the mouth. The juvenile can be bright red sometimes.

The most distinct feature of Cabezon fish is its head. The head is more significant than its body, and it has broad bony support extending from the eye across the cheek.

These fish have no scales and a dorsal fin with 11 poisonous spines. It also has a stout spine before the eye and fleshy flaps (cirrus) on the middle of the snout and just behind the eyes.

The anal fin has soft rays. It also has a broad mouth with many small teeth.

Where cabezon fish live

Cabezons live in a wide range of habitats of up to 200m in depth. They usually live in shallow waters in rocky, muddy, and sandy bottoms.

They are also found in intertidal pools, jetties, kelp forests, rocky reefs and areas with dense algal growth.

According to reports, older fish prefer to go to the deep ocean, as deep as 250 feet and even a depth of 798 feet. In contrast to rockfish and lingcod, which favor the sheer walls of ledges, Cabazons prefer the tops of rocky ledges.

These fish mostly stay motionless anywhere they find, no matter it’s a hole, on the reef, or on vegetation, until they find food.

They are opportunistic feeders that wait until the prey swims within their reach. They usually look for prey along the bottom. They mainly eat crustaceans, mollusks, and other fish.

Cabezons live in the cool water of 22-28 degrees Celsius. They do not tolerate high temperatures or low salinities, but they can survive in waters with poor oxygen content.

They also live in waters with a ph between 5 and 8.

Is a cabezon a lingcod?

Both Cabezon and Lingcod look alike because they belong to the same order. But, Cabezon is not a lingcod because Cabezon belongs to a different family.

Lingcod belongs to the greenlings family Hexagrammidae, while Cabezons belongs to the sculpin family Cottidae.

Both fish lives in relatively similar habitats, but, appearance-wise, they have distinct differences.

Lingcod are brownish in color with grey shades, but cabezons come in several colors. Also, Lingcod has a white spot behind the fish’s eye and a white margin on its dorsal fin, and Cabezon lacks these features.

Cabezon fish behavior

Cabezons are carnivore fish that “lie and wait” until their prey comes near them. Their color lets them blend in with their environment while sitting still.

When food passes by, they lunge at it with their big, powerful pectoral fins and tails and then swallow it with their giant mouths.

Cabezons spawn in shallow waters on the coastline. They are egg-laying fish that practice prenatal care.

The male fish tend to guard the eggs until they hatch, which causes them to expose to anglers. Otherwise, most adult fish often lives in the deep sea as deep as 250 feet and more.

What does the Cabezon eat?

Cabezons feed on a variety of foods which includes meaty food that can fit in its big mouth.

They swallow their food whole without chewing and have a pretty large mouth that can fit rather large fish.

They feed on crustaceans, squids, abalone, mollusks, fish, and fish eggs. Sometimes they also eat garbage from the seafloor.

The Cabezon’s large head shields its eyes from the sand. Some scientists believe that this is why it does not have a nictitating membrane.

Cabezon fish breeding

Cabezon fish breeding season lasts from October to March. They are egg-laying nest spawners that lay eggs to the nests built by male fish.

Once they finish spawning, the female fish goes back offshore, and the male fish start to guard the eggs until they hatch.

Several female fish may lay eggs in the same nest while the same male fish fertilizes them.

Once the eggs hatch, silver-colored fish fry comes out from the eggs and drifts away. Then, the male fish goes back to the shore.

The silvery fish larva settles under floating kelps in the ocean and lives in there until they get old enough.

As they become older, Cabezon tends to settle in tide pools, eventually making their way to the kelp forest to spend their adult life under rocks and hidden in the darkness.

Ecosystem balance

Cabezon fish are secondary consumers of the food chain that eat crustaceans, squids, abalone, mollusks, fish, and fish eggs.

Cabezon fish are also an important part of the food chain that plays a role in keeping oceans clean.

Their food sources usually eat garbage from the seafloor, decaying organisms, and other wastes and cabezons eat them. This keeps the ecosystem clean.
