In several deep-sea anglerfish species, males are tiny compared to females.
When a male finds a female, he bites her body and fuses with her permanently. His tissues merge into hers, and eventually, he shares her bloodstream. Over time, he loses his eyes, fins, and most internal organs—except his testes.
The female can carry multiple fused males, which she uses for fertilization when needed.
This bizarre reproductive strategy ensures survival in the sparse deep-sea environment, where encounters between potential mates are extremely rare.
