Which of the following is the first-ever animal that does not need oxygen to breathe?
Answer with explanationAnswer: Option D
Henneguya zschokkei, also known as Henneguya salminicola, is a species of a myxosporean parasite of certain species of salmons of genus Oncorhynchus. Researchers at Tel Aviv University have discovered a unique organism that doesn’t need to breathe. Henneguya salminicola, the tiny parasite, is the first known multicellular animal that can survive without oxygen. It lives in an anaerobic environment. The parasite lives in salmon tissue and evolved so that it doesn’t need oxygen to produce energy. The researchers made the discovery accidentally while sequencing the Henneguya genome.
