Short description Morphology | Morphometrics

Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 13-15; Anal spines: 2; Anal soft rays: 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.

Biology     Glossary (e.g. epibenthic)

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).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 25.5 - 25.6, mean 25.6 (based on 2 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00448 - 0.02337), b=3.01 (2.82 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.7   ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (22 of 100) .
