In a fascinating discovery, researchers have found that mother pufferfish provide their larvae with a nearly non-toxic chemical that effectively helps them escape predators. This chemical deters potential threats by making them unpalatable, thus improving the young fish's chances of survival. Additionally, this same chemical intriguingly attracts other pufferfish, revealing a unique dual role that aids in their survival strategies during vulnerable stages.
