Bioluminescence was reported on the beach in Visakhapatnam

The flowers of Noctiluca Scintillans, often known as “sea sparkle or bioluminescence,” can be seen along the coastline of Visakhapatnam, Andhra Pradesh.

Scintilla Noctiluca

  • Scintillans is a bioluminescent species that illuminates the seas at night.
  • It eats other microorganisms like larvae, fish eggs, and diatoms. The unicellular phytoplankton that lives inside it, on the other hand, can photosynthesize, converting sunlight into energy.
  • Even when nourishment was scarce, they helped their host cell thrive.
  • As a result, N. Scintillans functions as both a plant and an animal.

Potential dangers

  • The phenomena, according to marine specialists, is an indicator of climate change.
  • While smaller blooms may be harmless, larger blooms that move slowly may have an influence on deep-sea fisheries.
  • N. Scintillans poisonous blooms have been connected to huge fish and marine creature mortality.
  • Despite the fact that the species does not create a toxin, it has been discovered to accumulate dangerous levels of ammonia, which is subsequently expelled into the surrounding waterways and may operate as a killing agent in blooms.
  • They have replaced microscopic algae known as diatoms, which serve as the foundation of the marine food chain. This has resulted in a lack of food for planktivorous fish.
