For a peculiar species of sea slug, love involves losing more than just its heart. It means losing its penis.

Japanese scientists have been astonished to discover a sea slug species, the chromodoris reticulata, that discards its penis after mating, only to regrow another one 24 hours later.

Scientists believe this is the first known creature able to mate with a “disposable penis”.

After copulation, the’s chromodoris reticulata’s detachable penis drops off and will grow another one within a day.

The animals, discovered off the coast of Japan, unroll an internally coiled and compressed juvenile penis to replace the used part. The feat can only be performed up to three times.
