Halgerda willeyi Eliot, 1904 (Revisited)

While it is hard, if not impossible to say which of the Halgerda’s is the most beautiful, beauty being in the eye of the beholder, Halgerda willeyi is definitely one of my very favorites.

This simply gorgeous shot really shows of the delicate features of this species. Rigid bodied, the soft curves and subtle hues of color, provide an interesting contradiction. The subtle elegance of Uncle Bob’s photo above is not shared by all specimens of this species as seen by the variability of shape and color patterns reported on Bill Rudman’s Forum . A look back at BOW 11 (Wow you guys – that was done back in 1998) is an indication of that observation (Darn – Terry hasn’t changed a bit. And he still has my flexible flashlight).

This species reaches 5 cm in length and is found throughout the western Indo-Pacific. W
