Incapable of feeding themselves after they mature, male anglerfish must quickly seek out their mate by smell for their survival. After the male anglerfish finds a mate, he bites her skin. This releases an enzyme that dissolves his lips and her skin so they’re connected at the blood level. He is then able to permanently attach himself to her, allowing him to obtain nutrients. He is also able to inject her with sperm when hormones in her blood signal that she’s ready to release eggs.
