Explore the challenges facing amphibious fish when they leave water and the ingenious ways they survive on land. We think of fish as completely aquatic animals. But there are actually hundreds of fish species that are amphibious, meaning that they possess adaptations that enable them to survive on land. Once on land, however, they face suffocation, drying up, and being hunted by land predators. So why do fish make the exodus from water to land? Noah R. Bressman explores the ingenious ways these fish survive. Lesson by Noah R. Bressman, directed by Anna Benner

Walking catfish has also developed two defensive barbs in its neck just under its head near the gill that it also use to walk. This barbs are sharp, that is why never grab them in the scruff of their neck and down bellow which is also slippery. Grab it on the head

PUT IT BACK I M NOT READY FOR MERMAIDS.
But what s stopping us from making gills. Ie creating inorganic blood vessels to make gills and to connect it to a human s lungs and yet easily removable in a sense, I KNOW IT SOUNDS WEIRD BUT WE VE DONE WEIRDER

The narration and animation is superb as alwaus, but can the sound designer for this video get a special commendation? I especially enjoyed the Mummichog noises and would like to make that my ringtone (if I had one.

I have mosquitofish in an aquarium and couldn t imagine them flopping to another source of water (tons of fish are called mosquitofish though though so could easily be a different species.

It's the same thing like saying, why humans swim in water. Most of us have no cause of swimming but some may have. Just like that, most fishes have no reason of coming on land but some have.
reply

I have a doubt, is that true that sometimes got hurt in left side of brain makes us creative or more logical, if it is true then explain.

Fun facts: capelin do the same thing as California grunion but in Canada & Grunion don t only do their mass land spawning at night.
reply

So one with lungs can drown if tries to live like aquatic animals. Wish I could be an amphibian. It would be great fun. Maybe.

It remains me the ancestor of amphibi, they out from the water because the environment is too competitive and then they evolved.
