The 423 million years old Sparalepsis fish fossil revealed the secrets of fish evolution. Researchers from Flinders University, Australia and the Institute of Vertebrate Paleontology and Paleoanthropology, China found this fossil from Southern China
Accounting to the death of millions of marine lives, Lamprey remains one of the most barbaric fish predators. Scientists are trying various innovative ways to combat the ferocious sea evil.
While they may make great loofas, in the coral communities of the Caribbean reefs sponges are a greater threat than perhaps even humans. Aggressive competitors for resources and space, these nefarious neighbors have been known to use shading, smothering, snot and even toxins to kill their coral counterparts, literally living on what’s left of their remains. And without many natural predators, these sponges continue to damage reef-building corals unless kept under control.
In a surprising twist, scientists drilling through 2,500 feet or 740 meters of ice in Antarctica have stumbled upon a colony of fish, crustaceans and jellyfish inhabiting the cold and dark recesses of the barren Antarctic sea floor.
Without fins or bones capable of paddling, in terms of appearances, jellyfish may seem like mere drifters of the sea. But even in spite of their major deficits, including the absence of a heart and brains, these invertebrates have an incredible talent for swimming. So much so that no other creature under the sea can quite compete in terms of efficiency and skills. Though their tactics have long been misunderstood, a new study adds to the working knowledge that these brainless creatures are far more clever than we give them credit for.
A new study suggests that despite concerns of exposure to mercury, pregnant women that eat a lot of fish may not harm their unborn child. In fact, it could help prevent fetuses from having developmental issues later, as has been previously believed.
The newest discovery of fossilized fish, whose eyes have remained largely intact, has provided the proof that the human eye's ability to see in color developed hundreds of millions of years ago.
