Does proximity to aquatic pollution affect reproductive traits in a wild-caught intertidal fish? Secondary and tertiary consumers live longer, so there are fewer of them because they reproduce more slowly.

In the National Marine Sanctuary System, we see them in or near Olympic Coast, Greater Farallones, Cordell Bank, Monterey Bay, Channel Islands, and the proposed Chumash Heritage National Marine Sanctuaries. In contrast, sneaker type II males do not guard nests or court females, but instead, steal fertilizations from guarding males by either sneaking deep into the nest when a female is present, or by fanning sperm into the nest from the periphery. This crustacean has a similar, but not identical, luciferin compound which can apparently function in the photophores of the fish, as well.
