Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय सौफट रेज़ (सम्पूर्ण): 11-12; ऐनल सौफट रेज़: 11. Diagnosis: This species differs from its congeners of the Horsti complex (sensu Böhlke & Robins 1968) that have a pale stripe extending from the eye to the caudal-fin base by the following combination of characters: dark longitudinal stripe wide, reaching lower abdomen and base of anal-fin (vs. never reaching abdomen or base of anal fin); pectoral-fin rays typically 18 (vs. typically 17 in E. randalli and E. figaro and typically 16 in E. atronasum (Böhlke & Robins); anal-fin rays typically 11 (vs. typically 10 in E. figaro); oval spot present on snout (vs. no spot in E. atronasum and E. horsti (Böhlke & Robins), a "V"-shaped spot in E. prochilos (Böhlke & Robins), and a medial bar in E. xanthiprora (Böhlke & Robins), E. louisae (Böhlke & Robins) and E. lori Colin) (Ref. 52745).
Found over rocky reefs and calcareous-algae banks around the island. Observed in cleaning activities during the day (and most of its life-cycle) with clients varying from large-sized carnivores such as Carcharhinus perezi (Poey) to small-sized planktivores such as Chromis multilineata (Guichenot) (Ref. 52745).
