"Baby sharks stay still to avoid being detected by predators." -Science Daily -6/9/13
This article is about how some species of baby sharks can avoid being detected by predators by staying still. Researchers have found that even within their egg cases the brown-banded bamboo shark embryos can sense electric fields of a predator and stay still to avoid detection. They reduce the movement of their gills to stop moving so that potential predators won't notice them.
I chose this article because I never thought that even while still in their egg cases sharks could avoid detection by potential predators. I find that this is interesting because adult sharks are known to use receptors to detect their prey so this shows that even while the sharks were young they used those receptors but not for the same purpose. This is a very unusual thing and I have not herd nor read about anything similar before this.
This is significant because it shows that even at a very young age sharks used there receptors to avoid predators while when there older they use those same receptors to find their prey. Knowledge of these behaviors could possibly help us to develop effective shark repellents that could help keep people safer while near sharks.
