The walking catfish is a freshwater fish that can crawl across wet land to reach new water. It lives in Southeast Asia and has also been introduced to places such as Florida. Its spiny defence is the reason it needs careful handling.1

Kako jo prepoznaš

Elongated body, grey or grey-brown in colour1
Often covered on its sides with small white spots1
Long dorsal and anal fins, and several pairs of sensory barbels1
Scaleless skin covered in mucus1
No adipose fin, a small fleshy fin on the back near the tail1

Pogosto zamenjujejo z: It is often confused with North American ictalurid catfish and with close relatives such as C. magur. The walking catfish can be told apart from the North American ictalurid catfish because it lacks an adipose fin.1

Kako nevarna je za ljudi?

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

It must be handled carefully when fished because of its embedded sting or thorn-like spines. It is also harmful as an invasive species, because it eats the food of native fish, preys on their young and can destroy fish farms.1

Kaj naredi, ko se prestraši?

It has a sting or thorn-like spine hidden behind its fins, which it uses to defend itself.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.

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 18 hours out of water.1

It moves over land with snake-like wiggles, using its pectoral fins to stay upright.1

In Florida, fish farmers have had to put up fences to protect their ponds from them.1

It often rises to the surface to gulp air, because it breathes air as well as using water.1

Walking catfish were imported to Florida in the early 1960s for aquaculture, and escapes led to wild populations.1

In Indonesia it is known as lele and is the main ingredient in dishes such as pecel lele.1

Razbijalec mitov

Mit: The walking catfish truly walks on land like a four-legged or two-legged animal.

Resnica: It does not walk in that way. It uses its pectoral fins to stay upright while it wiggles its body in snake-like movements.1
