Anglerfish

The anglerfish can be found 2,000 meters below the surface. It was named as the anglerfish due to the presence of a strange glowing protrusion on its head which serves to lure its prey. The most interesting fact about the anglerfish is its mating ritual. The male fuses with the female anglerfish while mating and dies in the process. It dissolves afterward, while still fused to the female, until the only remaining part is its gonads
