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

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

Kaj je?

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

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

Če te zbode z bodicami

Rano daj v vročo vodo, tako vročo, kot jo poškodovanec prenese, ne da bi se opekel (preizkusi jo s svojo roko), za 30 do 90 minut. Poišči zdravniško pomoč, še posebej pri kamnitih ribah in morskih bičih.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te zbode z bodicami: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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
