Barnacles are stuck to rocks, which could make it tricky to get close enough to a partner to mate. They have solved this problem by evolving the longest penis relative to their body size of any animal. In this video the penises of several barnacles are probing the neighborhood for mates. The penis is re-grown each mating season. Check out creaturecast.org for more.This video was filmed by Stefan Siebert.

Description: Deep-water scalpelliform with reduced armament. Notable that the cirri are black – in other deep forms they have no pigmentation.
the inverted V shape of the tergum (the top plate on the head) indicates that the species could be either Alcockianum alcockianum or Alcockianum persona.
Alcockianum alcockianum has an Indo-west Pacific distribution, whereas A. persona has an Indo-Malayan distribution, although for the reasons indicated above, it would not be surprising to find this species in western areas of the Indian Ocean. The recorded depth range of A. persona is 109-915 m and that of A. alcockianum 945-1950 m, but again an extension to 2,500 m for either species would not be surprising.

This is a more "yellow" species. Trianguloscalpellum hirsutum is described as being a pale yellow to brown color whilst, although undescribed in the literature, in general Trianguloscalpellum regium specimens are whitish grey in color. The Indo-Malayan distribution of T. hirsutum, however, indicates that to date it has only been recorded from the eastern Indian Ocean, but since there has been little deep water sampling in the Indian Ocean in general, it would not be surprising to find it in western areas. The recorded depth range of Trianguloscalpellum hirsutum is 1507-6135 m, which fits with the 2,500 m collection depth and, therefore, this is possibly Trianguloscalpellum hirsutum as the "yellow" species.
