The stonecat is a small freshwater catfish from North America. It hides near or under stones in fast-moving water. It is special because it has venom glands at the base of its pectoral spines, which can cause extreme pain.1

Tuis

Stonecats live in large creeks to small rivers, usually in gently to fast-moving riffles with rocky bottoms. They also live in natural lakes such as Lake Erie, on rock and gravel bars that get strong wave action.1

Wat eet dit?

Stonecats are opportunistic bottom feeders. At night they use their sensitive barbels to search the river bed for aquatic insect larvae, mayflies, snails and other molluscs, minnows, fish eggs, crayfish, worms and plant material.1

Gifkrag

Giftige stekels

Skerp stekels dra die gif. Dit maak seer as jy daarop trap of dit gryp.

Wat doen sy gif as dit byt of steek?

Stonecats have venom glands, mainly at the bases of the pectoral spines. Their venom causes extreme pain, similar to that of a wasp sting. Other members of this catfish family cause irritating wounds from their spines, but the stonecat's venom is stronger.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

The spines can deliver venom that causes extreme pain, similar to a wasp sting. Keep clear of its spines.1

Wat doen dit as dit bang is?

Stonecats hide near or under stones, and their venom glands sit at the bases of their pectoral spines.1

As sy stekels jou steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As sy stekels jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

A stonecat's pectoral spines carry venom glands, which makes them far more painful than the spines of most related catfish.1

Its eggs are amber-yellow and very large for a fish, measuring between 3.5 and 4 mm across.1

Stonecats are used as indicators of water quality, because they are absent from highly polluted or heavily silted areas.1

Stonecats form monogamous pairs for breeding, and they spawn when water temperatures reach 25 °C.1

The upper jaw of the stonecat projects beyond the lower jaw.1
