Indian Squid

  • Behavior - Generally, squids are extensively known for their rapid growth rate, limited lifespan, and complex population structures
  • They are fast swimmers and are capable of propelling themselves through the water using a jet propulsion system.
  • This allows them to reach speeds of up to 40 km/h when escaping from predators or chasing prey.
  • Squids tend to prefer areas with high levels of dissolved oxygen, as this is crucial for their respiration.
  • Distribution - It is distributed in the Indo-Pacific region, occurring in depths between 30 and 170 meters.
  • Along the coast of India, squids are commonly found in the waters off the coasts of Tamil Nadu, Kerala, and Goa.
  • Diet - This species is an active carnivore that feeds mainly on crustaceans and small fishes and often exhibits cannibalistic behavior.
  • Conservation Status
    • IUCN - Least Concern.
  • Uses - Food resource, utilized as fertilizer supplemental food source for highend and expensive cultured animals.
