Lutjanus analis

Unique Characters: Anal fin angulated in larger individuals, the middle rays elongated, the longest almost half to greater than half length of head (anal fin rounded in L. analis less than about 4 cm standard length). A dark spot below anterior part of soft dorsal fin, at least in young, this spot present in L. analis to at least 46 cm standard length. Vomerine tooth patch without a distinct posterior extension on median line. Soft rays in anal fin usually 8, rarely 7. Spot below anterior part of soft dorsal fin relatively large in small individuals, small but distinct in large ones. Iris of eye red in life.
