A sea snail species has contrived a path for satisfying his feeding needs. The slow-moving snail paralyzes its next meal with a dose of insulin and afterward begins to devour the paralyzed prey. The snail’s venom doesn’t only kill the fish meal but it is also able to paralyze and kill a human being in certain circumstances.
There are numerous types of sea cone snails; however, the Geographic Cone Snail (Conus geographus) is the most poisonous of all. The tiny creature shoots a lethal billow of insulin at any fish mark it wants to execute and the insulin blast causes the prey’s blood sugar levels to climb impressively, and puts the victim into an immobile state. The snail’s insulin is not quite the same as other sorts of insulin since it contains only 43 amino acids which are less contrasted with other sorts. With further studies, the venom could become a form of treatment for of controlling sugar and digestion system in people.
Christopher Meyer, a cone snail pro at the Smithsonian’s National Museum of Natural History remarked that the fish appear to be in an overdosed state. The specialist was not part of the study.
When the fish’s blood sugar level has tumbled it leads to a trance like state. Then, the cone snail reaches forward and grabs the stunned prey into its mouth where it stings the fish again with an alternate set of poisons which totally incapacitates the fish. This makes ‘having lunch’ a much easier process.
Helen Safavi-Hemami, a specialist on venoms and toxins at the University of Utah in Salt Lake City uncovered that cone snail has other chemical mixes in its venom that deliver the same results as dazzling or incapacitating the prey. These joint compounds, including the insulin weapon have been named “nirvana cabal” by researchers, in light of the fact that their main role is to stun a prey into stupor or unconsciousness.
Meyer, who has done some research on a close relative of the geographic cone snail named Conus tulipa observed the same features at the Guam tiny predators. Having examined why stung fish pass out before their predators, Meyer now comprehends the impacts of the shots and how it manages to drop glucose levels before an alternate set of poisons hold the victim still.
In the past, some human divers have been killed while attempting to get the lovely shells of the sea cone snail. This was possible because the toxins released by the snail can shut down the system of its victims. This study was distributed in the Proceedings of the National Academy of Sciences.
Humans and this species of snails are the only ones on Earth known to kill using insulin. The geographic cone snail is recognized as the most poisons snails on our planet.
