This species has only been reported once in the scientific literature.[1] DescriptionThe adults of Huffmanela lata are unknown, only the eggs were described.[1] The eggs are 77-88 (mean 84) micrometers in length and 52-63 (mean 57) micrometers in width, with a thick (6-8 micrometers) shell, apparently spinose. Mobile larvae, 200-250 micrometers in length, were visible in the eggs. BiologyAs it is often the case for species of Huffmanela, the species was found because the accumulation of its eggs produced a black spot; in this particular case, the black spot was on the skin of the shark, near the gill. No adult were found.[1] The biology of Huffmanela lata is unknown. Its eggs are probably released from the skin with the turnover of living tissues and immediately continue their life-cycle. The intervention of an intermediary host in the life-cycle (possibly an invertebrate) is possible, as it has been suggested for other species of Huffmanela.[2] However, it is also possible that transmission of the parasite from shark to shark occurs when sharks congregate and skin-to-skin contacts between sharks are frequent.[1] Other species of Huffmanela are known from other sharks.[3][4] See also
