TL;DR: Electrical stimulation of the isolated eyestalk of Uca pugilator induces the release of several peptides which affect epidermal chromatophores, but no red pigment dispersing hormone (RPDH) was detected at any voltage.
Abstract: Electrical stimulation of the isolated eyestalk of Uca pugilator induces the release of several peptides which affect epidermal chromatophores. Thresholds for release of these peptides were different, that for red pigment concentrating hormone (RPCH) being lowest, for black pigment dispersing hormone (BPDH) highest, and for black pigment concentrating hormone (BPCH) intermediate, but no red pigment dispersing hormone (RPDH) was detected at any voltage. Neurotransmitters, known to be present in crustacean central nervous systems, induced chromatophore dose dependent responses. Norepinephrine induced BPDH release, and dopamine induced both RPCH and BPCH release.

TL;DR: The findings of enzymes present in egg mass fluid throughout maturation inform a large body of work on pheromones and hatching cues for blue crabs and suggest that the same suite of enzymes is important to biochemically manage biofilms in two ecologically relevant contexts.
