Numerous studies have shown that melatonin exerts some influence on the antioxidant defense system (ADS) in vertebrates, but
for crustaceans no such effect has been demonstrated till now. However,earlier reports did show ...

The first and main target-structure of ultraviolet (UV) radiation in animals is the body surface, including the skin and eyes. Here, we investigated cell damage in the visual system of the crab Neohelice granulata
acclimated ...
