The hardhead catfish is a sea catfish that lives in shallow coastal waters of the northwest Atlantic and the Gulf of Mexico. It has sharp spines on its fins that can be venomous, so it is one to admire from a distance. Male hardhead catfish also carry their eggs in their mouths until they hatch.1

It eats a wide range of food, including algae, seagrasses, crabs, shrimp, sea cucumbers, worms and small fish. It hunts on mud and sand flats, using its barbels to find prey in murky water. Younger fish eat small crustaceans, while adults mainly eat larger fish.1

Uni qanday tanish mumkin

  • Often dirty grey on top with white underneath.1
  • Four barbels (whisker-like feelers) under the chin and two more at the corners of the mouth.1
  • A hard, bony plate between the eyes and the dorsal fin.1
  • Sharp, barbed, slime-covered spines on the dorsal and pectoral fins. The dorsal spine stands upright when the fish is excited.1
  • Typically 25 to 30 cm long, and elongated in shape.1

Koʻpincha adashtiriladi: The gafftopsail catfish looks very similar. The difference is that its dorsal and pectoral spines have a fleshy extension, like the fore-and-aft topsail of a ship.1

Odamlar uchun qanchalik xavfli?

Odamlar uchun xavf: OgʻriqliJuda ogʻritishi mumkin, lekin deyarli hech qachon jiddiy emas.

No bite or death figures are given. Anglers generally avoid catching it because of the risk from handling the fish and its spines, and because its flesh tastes fishy compared with popular game fish.1

Qoʻrqqanda nima qiladi?

When it feels threatened or excited, its dorsal spine stands upright, and its sharp, slime-covered spines are its main defence.1

Faktlar

1

Male hardhead catfish are paternal mouthbrooders: they keep the eggs and young in their mouths, and do not feed while doing so.1

2

Some researchers suggest they may use low-frequency sounds to detect and avoid close obstacles, which is an unusual ability for a fish.1

3

They can make sounds by vibrating thin bones near the swim bladder, and by grinding their throat teeth or rubbing their pectoral spines. These sounds appear to be a fright response.1

4

Hardhead catfish respond to chemical alarm signals released by injured members of their own species, with their activity increasing right after the signal. They are the first marine catfish found to show this type of alarm reaction.1

5

They can live for over 24 years.1
