Etymology: itajobi: The name signifies 'green stone or emerald' (ita = stone; jobi =green) in 'Tupi', a native South-American language; refers to the emerald-green color of the species and an allusion to its type locality known as 'The Emerald of Atlantic'.

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 12; Rückenflossenweichstrahlen (insgesamt): 13-15; Afterflossenstacheln 2; Afterflossenweichstrahlen: 15 - 16. Distinguished from its Atlantic congeners by the following combination of characters: a small blue spot on the 2nd dorsal spine (noted mainly in adult males), head with tiny black spots (vs. speckles absent in Scartella cristata), modally 14 segmented dorsal-fin rays (vs. 15 in S. cristata from Brazilian localities, S. caboverdiana, and S. nuchifilis; and 16 in S. springeri), modally 15 segmented anal-fin rays (vs. 16 in S. poiti, 17 in S. cristata from Brazilian localities, S. caboverdiana, and S. nuchifilis; and 18 in S. springeri), and modally 23 caudal vertebrae (vs. 24 in S. cristata from other Brazilian localities, S. caboverdiana, and S. nuchifilis; and 25 in S. springeri) (Ref. 80496).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Collected in shallow-waters and tide pools of the type locality. Similar to its congeners, this species is extremely tolerant to salinity and temperature variations. Some individuals were also found in small crevices of emerged rocks (2 meters above sea surface), remaining up to 20 minutes out of the water, probably avoiding predators. (Ref. 80496). Similar to its congeners, this species is 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).
