This image shows extensive histamine containing cells in metamorphic all competent sea urchin larvae (Strongylocentrotus purpuratus). Now that hay fever season has started, sufferers are well aware of the effect of histamines. However it is easy to forget that histamine is also a neurotransmitter involved in controlling memories, regulating sleep, and controlling secretion of gastric acid. New research published in BioMed Central's open access journal BMC Developmental Biology shows that for the purple sea urchin (Strongylocentrotus purpuratus) histamine is also responsible for controlling metamorphosis from a free swimming larval form to the spiny adult living on the sea floor.
