Abstract We describe the life-history pattern of Phalloceros caudiomaculatus on the basis of wild-caught and preserved fish from four different South American locations and laboratory data on livestock from a fifth location. This species is matrotrophic; the estimated dry weight of the young at birth is up to five times the weight of eggs at fertilization. In addition, these fish lack superfetation, meaning that there is only one brood of developing young at a time. This observation suggests… CONTINUE READING
