Question

The male of what species testicles explode on mating and then dies?

Answer 1

The male of the Australian redback spider species has testicles that explode on mating and then dies. This happens because the male spider transfers a large amount of sperm to the female during mating, which causes his testicles to burst and his abdomen to rupture.

Answer 2

The male of the honeybee (Apis mellifera) species has testicles that explode on mating and then dies. This phenomenon is known as "apocrine secretion." During mating, the male honeybee's endophallus (a genital structure) ruptures, causing the male bee's testicles to explode and ultimately leading to its death. The explosion of the testicles is thought to be an evolutionary adaptation to provide a competitive advantage to the strongest, most genetically fit males. The queen bee stores the sperm from the males in her body and uses it to fertilize eggs to produce offspring.
