Sharks, apex predators of the ocean, exhibit a peculiar trance-like state called tonic immobility when inverted, rendering them temporarily paralysed. Scientists induce this state to safely study sharks, reducing stress during research. While the evolutionary purpose remains debated, theories suggest it could be a defence mechanism, aid in mating, or simply be an evolutionary remnant.from Science News: Fresh Discoveries, Research & Breakthroughs https://ift.tt/pi12Aam
