https://www.nytimes.com/2020/07/30/...te=1&user_id=33e9b2b47b7f7761a48a8053d434359cBorn into an inky deep sea world, the males of certain anglerfish species exist solely to sniff out their mates. Upon locating his lady (who might be up to 60 times his size), the male will nip at her belly. His mouth then dissolves in a sludge of chemicals that physically fuse him to his bioluminescent bride, forever commingling his blood and tissues with hers.
With the help of modern genetic sequencing, Dr. Boehm and his colleagues may have solved this deep sea dilemma. Anglerfish have largely jettisoned a branch of the immune system that’s been a fixture of vertebrate bodies for the last 500 million years, they report in a study published Thursday in Science. The adaptation may help the clingiest of couples stick together.
It’s a substantial sacrifice to make, even for sex: Similar changes would be lethal for humans — and no other animals have yet been documented doing the same.
never heard of that one before!
