An Anglerfish
What a strange, strange creature. Those bumps remind me of rivets on a submarine. But because they are anglerfish, the bumps are even more bizarre than you’d expect:
Since anglerfish are deep sea creatures, it took scientists years and years to figure this stuff out. They could never find a male. Females preserved in formaldehyde sitting on dusty museum shelves usually have strange lumps that appear to be parasites. They ARE parasites. Sexual parasites!
Those lumps are all that is left of the males! They had taken that last bite and had become absorbed into the females’ bodies and became nothing more than dangly bits. The male’s eyes and fins atrophy away, and nourishment comes from the female’s blood.
Lovely.
