-- Reference material: 1 specimen; 11/97: S4 (P39922);

-- Distribution: This species is a new record from the area of the Canary Islands, but was already recorded from the Azores before. The only specimen was caught at a neritic station southeast of Fuerteventura at a depth of 22 – 35 m during the day in autumn.

¬ SCORPAENIFORMES All fish have the suborbital stay in common. Larvae possess large pectoral fins, which are pigmented and have an extensive head spination, which varies among the Scorpaeniformes. Many species have an extended pelagic juvenile stage.

SCORPAENOIDEI > Scorpaenidae The myomere count is 24 – 27. Preflexion larvae are elongate to moderately deep bodied but becoming more robust in the postflexion stage. The gut is initially straight, but coils fast, what results in a preanal length of 1/3 to 2/3 of BL. The gas bladder is small. Pigmentation is in general very light, but prominent on the pectoral fins (Figure 55). Further pigments are located on the head, along the ventral and lateral midlines on the caudal peduncle and on the gut.The shape of the head is very variable and the eyes are large and round. The mouth is moderate to large and full with teeth, which form after flexion at a size of 5.5 – 5.8 mm. The ridges and spination on head are well developed, with the largest spines found at the preoperculum. The large pectoral fins form early and are fan shaped with rays extending to the anus and even reaching the caudal fin in some species. Between the anus and the origin of the anal fin an interspace is present. The posterior anal fin spines form first as soft rays and transform to spines before settlement. There are no scales before the settlement developed.
