Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 11 - 12; членистые (мягкие) лучи спинного плавника (общее число) : 13 - 15; колючие лучи анального плавника: 2; членистые (мягкие) лучи анального плавника: 15 - 16. Diagnosis: This species is distinguished from its Atlantic congeners by its speckled body and head with small black spots (vs. absent in S. cristata); modally 14 segmented dorsal fin rays (vs. 15 of S. cristata from other Brazilian localities, S. caboverdiana, and
S. nuchifilis; and 16 in S. springeri); modally 16 segmented anal fin rays (vs. 17 of S. cristata from other Brazilian localities, S. caboverdiana, and S. nuchifilis; and 18 in S. springeri); modally 19 nuchal cirri (vs. 22 in S. cristata from other Brazilian localities, 5 in S. springeri, 6 in S. nuchifilis, and 17 in S. caboverdiana); and, modally 23 caudal vertebrae (vs. 24 in specimens of S. cristata
from other Brazilian localities, S. caboverdiana, and S. nuchifilis, and 25 in S. Springeri ). The means of counts of dorsal and anal rays are additional diagnostic characters.
Body shape (shape guide): fusiform / normal.
Recorded from 0.1 to 1.0 meter depth inside tide pools and in the surf zone over crustose algae or volcanic reefs. Observed to be extremely tolerant to high salinity and temperature variations. Adults occur with other blennies (Ophioblennius cf. atlanticus and an undescribed species of the genus Entomacrodus, labrisomids (Labrisomus nuchipinnis and an undescribed species of Malacoctenus), the Trindade damselfish (Stegastes fuscus trindadensis), and a Brazilian wrasse (Thalassoma noronhanum) (Ref. 49353). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
