What biological event initiates the transformation of the deep-sea male anglerfish into a permanent appendage?
Answer
He bites onto the female, initiating a fusion of tissues and circulatory systems
The most dramatic aspect of sexual dimorphism in deep-sea anglerfish involves the reproductive strategy where the male adopts a parasitic existence. This transformation begins when the much smaller male successfully locates a female, often guided by chemical cues in the dark waters, and subsequently bites onto her body. This bite is not merely superficial; it triggers a profound biological change where the tissues and circulatory systems of the male and female physically fuse together. This complete integration means the male is subsequently sustained entirely by the female’s bloodstream, effectively becoming a permanent, living sperm bank attached to his host.
