Why in news?
India's first scientifically confirmed case of freshwater pufferfish poisoning has recently emerged as a significant public health concern.​
Key Facts About Pufferfish
- Defense Mechanism: They can inflate their bodies by swallowing water (or air when out of water), making themselves look larger and harder to eat.
- Toxins: Many species contain tetrodotoxin, a powerful neurotoxin that makes them highly poisonous to predators (and dangerous to humans if consumed improperly).
- Diet: They feed on algae, invertebrates, and sometimes shellfish. Their strong beak-like teeth help them crush hard shells.
- Habitat: Found in warm and temperate seas worldwide, often near coral reefs and coastal regions.
- Appearance: They have distinctive, often colorful patterns and spines that become more pronounced when inflated.
