 | | Also in Table 9, for the character "serrations on dorsal and pelvic fin spines," the entry for L. campechanus states, "on anterior spine margin only." Larvae of L. campechanus develop serrations on the anterior margin of the pelvic spine only, not on the dorsal spines (Collins et al., 1980; Potthoff et al., 1988). | | | The unique condition of pelvic-fin pigmentation that characterizes L. griseus is the "candycane stripe" pattern of melanophores that overlay the pelvic spine. | | | The second spine of the dorsal fin was first to develop followed by the third, then the first and fourth spines. |
