5 Fish With Unbelievable Survival Skills. These fish all posses unbelievable and unique survival skills. Amazing creatures! Fish that will survive almost anything!
5. Cave Fish
Cave fish don’t have eyes, because they live in perpetual darkness. They have a super sense called “hydrodynamic imaging.” All fish have an organ called a “lateral line” down the length of their body, which detects vibrations and the flow of water around them. In cave fish, this sense is super enhanced. They can feel walls, rocks, and obstacles just by swimming around. It’s like an extended sense of touch. The change in the field of flow around their bodies lets them build up a map of what is around them.
You cannot kill the mummichog. It can live practically anywhere. Is your harbor full of lethal polychlorinated biphenyls that cause fatal liver damage? The mummichog laughs it off. Even in grimy rivers covered in oil slicks, this little fish lives happy and healthy. If it’s confronted with a low-oxygen environment, it either breathes at the surface or changes its blood to bind more oxygen. The Mummichog don't care…
3. The Tonguefish
The tonguefish lives in a shallow chain of underwater volcanoes in the Mariana arc between Guam and Japan. Reaching temperatures of over 180 degrees Celsius (356 °F) and spewing out sulfuric and toxic heavy metals, this is a hard place to live! So what is causing these weird-looking fish to thrive? Scientists don’t know yet. Nor does anyone really know how a fish can live right up against pools of boiling toxic sulfur. They have been seen lying in pools of sulfur without a care in the world… What you call Hell, they call home.
No matter how many abilities fish have, there’s still one universal rule: They’re stuck in the water. Or not? The mangrove killifish has found a way around this rule. It can live inside of rotting trees and branches on land for months — it’s called “logpacking.” This is a fish that lives in trees. When pools dry up or the water recedes, mangrove killifish will jam into old trees, hollow coconuts, discarded coffee cans, or just under the leaf litter. As long as it’s kept moist, the killifish can survive like this for 60 + days.
1. The Cleaner Wrasse
The bluestreak cleaner wrasse is one of several species of cleaner wrasses found on coral reefs from Eastern Africa and the Red Sea to French Polynesia. Like other cleaner wrasses, it eats parasites and dead tissue off larger fishes' skin in a mutualistic relationship that provides food and protection for the wrasse, and considerable health benefits for the other fishes. The "catch"? They enter the mouths of their hosts, clean them and then the hosts lets them back out…
