Abstract
Hydra viridissima (formerly Chlorohydra
viridissima) appears green, owing to its symbiotic relationship with the
green alga, Chlorella vulgaris, which are present in the body of
the Hydra. Hydra viridissima are carnivores and are able to consume
animals roughly the volume of their own bodies. The objective of this
experiment was to study the symbiosis between Chlorella and Hydra
along with the population regeneration of Hydra viridissima in varying
conditions of feed of Moina macrocopa and light. The
Hydras were maintained in dechlorinated water under five conditions viz.
Light conditions:- no feed - only light, feed as well as light, Dark
conditions:- only feed – no light, no feed- no light, excessive feed – no light.
The set up was observed for 14 days continuously. Moina macrocopa, which
is a crustacean, was cultured separately in bottles. It was observed that the
best regeneration of Hydra viridissima occurred in feed as well as light
conditions. It was also observed that Chlorella leaves hydra when there
is insufficient light and Hydras became pale coloured.
