Hardhead catfish
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

怎样认出它
- 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
常被误认为: 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
毒液之力
锋利的刺带着毒液。踩到或抓住它会很疼。
它对人有多危险?
对人的危险: 很疼可能真的很疼,但几乎从不严重。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
它害怕时会做什么?
When it feels threatened or excited, its dorsal spine stands upright, and its sharp, slime-covered spines are its main defence.1
如果它的刺扎到你
- 把伤口泡在热水里,水温以不烫伤为限、尽量热(先用你自己的手试一试),泡 30 到 90 分钟。去看医生,尤其是被石头鱼和魟鱼伤到时。
一定先拨打你的急救电话(112、000、911)。这里是一般急救指导,不是医疗建议。 急救基础
注意安全
- 永远不要摸、抓或逗弄野生动物,即使是很小的,即使它看起来在睡觉或已经死了。
- 给它留出空间。如果遇到它,保持冷静,慢慢后退,让它走自己的路。
- 如果它的刺扎到你:保持冷静,保持不动,拨打你的急救电话(112、000、911)或尽快去医院。记住它长什么样,拍张照片会有帮助。
它不是冲着你来的。它用毒液捕猎或保护自己,而且它更愿意躲起来。 更多安全知识

事实
Male hardhead catfish are paternal mouthbrooders: they keep the eggs and young in their mouths, and do not feed while doing so.1
Some researchers suggest they may use low-frequency sounds to detect and avoid close obstacles, which is an unusual ability for a fish.1
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
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
They can live for over 24 years.1
