Diagnosis: The modal fin-ray count of D-XXX,1 A-II,17-18 and P-13 indicates Paraclinus nigripinnis. Several species share the single segmented ray as the last dorsal-fin element and all of these also have a small third pelvic-fin soft ray (vs. only two), although only P. marmoratus (D-28+1, A-II,19-21) and P. barbatus (D-28-29+1 A-II,19-20) share the mode of 13 pectoral-fin rays. (DNA) Description: Pre-transitional larvae: Body long, narrow, and thin with a medium round eye, pointed snout, and terminal medium mouth. Larvae can range from hunched-over to long and straight. Long continuous dorsal and anal fins with a very short and narrow caudal peduncle. Pectoral fins medium, reaching to the vent, and pelvic fins relatively long and thread-like. In later larvae, a notch develops in the membrane between the first three dorsal-fin spines and the rest of the fin. There are no surface melanophores along the dorsal aspect of the body. There is usually a cheek melanophore on each side. There are no melanophores along the caudal-fin base. Along the ventral midline there are melanophores at the isthmus and deep behind the pelvic-fin base. Along the anal fin there is a melanophore at the base of each anal-fin soft ray (sometimes also at the second spine and sometimes sparing the last and/or second-to-last ray), closely followed by one to three along the ventral midline of the caudal peduncle (uncommonly none), with the last in the series often on the rim of the procurrent caudal finfold. Some larvae have additional markings: a small midline melanophore on the abdominal promontory just forward of the vent and/or another or two midway along the abdomen and/or (rarely) a melanophore on the lower inner cleithrum inside the gill cavity on each side. Internal melanophores comprise only the basic complement: the nuchal midline (often obscured), otic capsule, and overlying the abdominal organs. Transitional stage: P. nigripinnis larvae are not caught with metamorphic melanophores, which must apparently develop after settlement. Transitional larvae often have developed cirri without any change in markings. Some larvae have additional melanophores along the ventral midline of the abdomen, but they are not the most developed larvae in the collections and the abdominal markings are present on early-stage larvae as well. Analogues: Larval P. nigripinnis are not easily distinguished from larvae of the other common species, P. fasciatus. Unfortunately their fin-ray counts can overlap and the diagnostic differences only become clear in well-developed larvae. P. nigripinnis larvae are distinguished by having the last element of the dorsal fin a soft ray (vs. all spines), a relatively short pelvic fin reaching less than halfway to the vent with a tiny third ray (innermost) (vs. longer than halfway and only two soft rays), and usually one or two fewer anal-fin rays. Unfortunately the last dorsal-fin ray and the third pelvic-fin ray can be difficult to discern without staining the fish (and some P. nigripinnis never form the last dorsal-fin ray) and there is some overlap in the length of the pelvic fins before transition. Furthermore, both species have many individuals with 18 anal-fin soft rays. It is likely the two species are only reliably distinguished by eye when in good condition and near the settlement stage.
Paraclinus nigripinnis, the Blackfin blenny, is a species of labrisomid blenny native to the western Atlantic Ocean and the Caribbean Sea from southern Florida to Brazil. It inhabits coral reefs, areas of eroded limestone, tide pools, and rocky areas with algal growth down to depths of around 10 metres (33 ft). This species can reach a length of 6.5 centimetres (2.6 in) TL. It can also be found in the aquarium trade.[2]
