Sunfish
The plectognath (aka mola) is one amongst those rare animals that servesno purpose on this Earth. they're strange-looking with their giant eyes
and lips and their inability to shut their mouths because of their strange
teeth.
In addition, they're exceptionally at risk of parasites and
predators. Not that they need several, of course. The 4.3-meter (14 ft),
2,300-kilogram (5,000 lb) fish exists on a diet of alga, plankton, and
jellyfish. of these foods square measure low in nutrition, that makes them the fish
equivalent of lettuce.
This unfortunate creature additionally lacks a sac, a very important
organ that almost all fish possess to assist them float. The sunfish has got to make amends for this missing organ with each in. of its body,
specifically with a layer of jelly underneath its skin that creates it neutrally
buoyant.
In fact, the sole reason the sunfish continues to exist is as a result of it lays
up to three hundred million eggs at a time. this might be spectacular except that
their strategy is to dump all three hundred million into the water close to a male and
hope that the eggs square measure inseminated and survive to hatch.
