Fish. Biol. | Abstract: | Among Sparus sarba, Acanthopagrus latus, A. schlegeli and Pagrus major, P. major had the largest egg size, with the biggest micropyle funnel and the most numerous accessory openings. The reinforcement in the micropyle canals was species specific with eight spiral clockwise, five two-spiral clockwise, seven two-spiral clockwise, and 10 triangular ridges in S. sarba, A. latus, A. schlegeli, and P. major, respectively. A key to identify these four species based on micropyle characters is proposed for future applications. Cladistic analysis by using different parsimonious methods on the morphological character of the micropyle suggested that the generic interrelationship between Sparus and Acanthopagrus was closer than to the genus Pagrus. Furthermore, the congeneric species of A. latus and A. schlegeli were the most closely related, with S. sarba the second, and P. major the last. This result agreed with conclusions obtained from other character suites including morphological, biochemical and molecular data |
