Why Sharks Freeze Upside Down Remains a Mystery, Say Scientists

quick Summary:

• Sharks exhibit a phenomenon called “tonic immobility,” where they freeze and stop moving when turned upside down.
• the condition is involuntary, similar to the freeze responses seen in other animals like rabbits, possums, and snakes.
• Scientists frequently enough use this behavior to safely handle sharks during studies.
• A recent study tested 13 different species of sharks, rays, and chimaeras; seven exhibited tonic immobility while six did not.
• The study rejected prior theories about the behavior being an anti-predatory trait or related to reproduction, suggesting no proven survival benefits for sharks.
• Sensory overload as a trigger for tonic immobility remains unverified and still requires thorough investigation by researchers.

Indian Opinion Analysis:
Exploring behaviors like tonic immobility enhances our understanding of marine ecosystems as well as shark physiology-a key step toward effective conservation strategies globally, including India’s coastal areas home to diverse marine life. Sharks are crucial apex predators in maintaining ecological balance but frequently enough face challenges such as overfishing and habitat destruction worldwide and along india’s coastline.

While no definitive explanation exists yet for this peculiar freezing phenomenon among sharks, studies like these contribute critically toward unraveling their biological mysteries-knowledge essential for ensuring informed preservation efforts amid growing environmental pressures. In nations rich in biodiversity like India, advancing research collaboration on such topics can significantly benefit both scientific inquiry and conservation policy.
