Creatures located in bodies of water and the sea are definitely much different compared to other creatures on the earth. With a wide variety and millions of known and unknown species, it is surely a huge space for scientists and researchers to discover new things.
The most common animal in the sea kingdom is the Copepods, which constantly releases substance in the ocean. These substances comes in high amounts and concentrations which affects the whole sea conditions accordingly. A research conducted by the University of Gothenburg focused on studying the impact that Copepods causes on the ocean in terms of the food web.
To begin with, the substance released by Copepods is called copepodamides, which is used by phytoplankton to avoid being eaten. Avoidance include producing light, bioluminescence; while other phytoplankton shrink in size to hide or release toxic substances.
Erik Selander from the Department of Marine Sciences at the University of Gothenburg is the leader of the research and stated, “Since the phytoplankton in the ocean are the basis of all marine life, the effects become large-scale. The substances are remarkably potent. Very small quantities produce large systemic effects. The amount of copepodamide that would fit in a grain of salt are enough to cause phytoplankton in a whole swimming pool to mobilise their defences. Some of the defences involve very strong toxins, and as a result copepodamides can have far-reaching effects such as toxic algal blooms.”
The study has shown many different effects that tiny creatures such as Copepods can cause on the huge body of water.
