Bermudas Terrestrial Smiling Worm (Prosadenoporus agricola)
The Bermudas Terrestrial Smiling Worm was described in 1874, it was restricted to the Bermudas Islands.
The milky-white, brownish or greenish colored species was commonly found along the shores of mangrove swamps, under stones and logs on moist, silty soil or inside earthworm burrows above the high-water mark and, during the wet season, also on adjacent hillsides.
The former habitat of this species is now completely lost due to commercial development.
Some very few last survivors – the last of their kind – were found during intensive field searches in 1966, since then the species is considered extinct. [1]
