In the extreme mating strategy of anglerfish, which two physical features does a male permanently lose after fusing to a female?

Answer

His eyes and fins

Once a male anglerfish bites onto and fuses with a female, his body degenerates until his eyes and fins disappear, leaving him as a permanent, sperm-producing attachment.

💡 Did you know?

Anglerfish females absorb males into their bodies until they become fused gonads—a grotesque symbiosis where the male loses eyes, fins, and autonomy.
