The brown bullhead is a catfish with a sharp, venomous spine on its fins. It lives in lakes, ponds and slow streams across North America, and it is important to the Ojibwe people, who see it as one of their clan symbols.1

Kako jo prepoznaš

Dark brown-green back that becomes lighter green and yellow towards the belly, which is off-white or cream1
Dark brown-black speckles over the whole body1
No scales1
Eight barbels (whisker-like feelers) around the mouth, with black to yellowish brown barbels on the chin1
Adults usually measure 20 to 50 cm and weigh 0.5 to 3.6 kg1

Pogosto zamenjujejo z: The black bullhead and yellow bullhead are similar. The brown bullhead has yellow-black chin barbels, no pale bar at the base of the tail (which the black bullhead has), and 21 to 24 rays in its anal fin. The flathead catfish lacks the brown bullhead's tooth patch on the upper jaw.1

Moč strupa

Strupene bodice

When attacked, the bullhead stiffens the sharp spine on the front edge of its dorsal and pectoral fins. While doing this, it releases venom that stings and burns the predator.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

Its fin spines can sting and burn, which is its main defence against predators. Treat any caught fish with care and avoid handling its spines.1

Kaj naredi, ko se prestraši?

When attacked, it stiffens its fin spines to make it harder for a predator to swallow it, and releases venom to sting and burn.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

It can survive very low oxygen levels, down to 0.2 ppm, and even heavily polluted water.1

Its spines can produce venom, which is unusual for a catfish species that is otherwise common and widely eaten.1

The brown bullhead is one of six beings in Ojibwe tradition that came out of the sea to form the original clans.1

Both males and females are known to eat their own eggs at times.1
