In the article the cone snail and its venom is described. Cone snails are one of the most deadly animals in the ocean. They use their “harpoon like teeth” to inject venom into their prey. Allowing this venom to target specific prey is the genes that are very fast evolving. “The fasting evolving genes in the animal kingdom.” A researcher found that in cone snail venom, the variety of neurotoxins, varies by location. Where there is more prey for the cone snail, the more “diverse” the venom is. The diverse amount of venom allows the cone snails to attack a wider range of species.
The discovery, all though not having much impact on our world as humans, has a big impact on the animal world. Scientists are also gaining from this discovery, allowing them to learn more about these animals and what they are capable of. For example, scientists have learned that, “prey diversity affects the evolution of predation genes.” It has an impact on the animal world as well. For example, this article explains just how dangerous cone snails are to their pray. Being able to diversitize their venom, according to where they are, and how many types of prey there are. Although the impact is so little on us, it is a big find for marine biologists.
I felt that in this article, they could have explained more on how they came across the fact that cone snails venom can be diverse according to where they are. The article also lacked some much needed evidence and facts. But, at the end of the article was another article that extended to this, which was very information, and well written. I used that article with this article to further my knowledge on this new finding.
