Whilst I was reading about the wonders of the naked mole rat and how a simple molecule prevents them from getting cancer, I came across this post - Evolution Fucked Your Shit Up: The World’s 50 Freakiest Animals!
I introduce to you my favorite - the Blobfish (although the Sea Dragon is also pretty cool)!
Now, the first thought that went through my head, is there an evolutionary reason the Blobfish looks so ugly? Why does it have such a squashed up nose and far apart eyes? Why does it even have eyes??
Then I came across this article that gave me more of an insight into its little blobby life:
These fish eventually evolved to where they no longer have any gas-filled air sacs in their body, rather they are composed of a gelatinous substance which allows them to float just above the ocean’s floor. This is an advantage, as competition for food is nearly non-existent on the ocean floor (although food itself is scarce), and their lack of air-sacs keeps them from exploding under the immense pressure of the water above (Blobfish commonly live in depths up 800m deep).
Another evolutionary trait gained by the Blobfish is it’s inability to swim. The gelatinous composure of the fish allows the creature to simply float and remain stationary in the water. Due to their astonishingly low consumption of energy, the Blobfish has little need for extra sustenance, and simply sucks down any food that happens to float in front of their mouth.
So overall, the Blobfish can’t swim, it doesn’t really eat - it just floats above the ocean’s floor! Sounds like a fun little life :)
