from
Wikipedia
In Nova Scotia, Canada, a form of three-spined stickleback departs from the usual pattern of parental care.
Unlike other sticklebacks who nest on the substrate, Nova Scotian male sticklebacks build nests in mats of filamentous algae.
Surprisingly, almost immediately after fertilization the males disperse the eggs from the nest and resume soliciting females for eggs.
Because these males have reduced dorsal pigmentation, resulting a pearlescent white appearance, they have been dubbed " white stickleback ".
It is currently unknown whether they are a distinct species, or simply a morph of the common Atlantic stickleback.
