Ecsenius kurti Springer 1988

Description: Dorsal fin XII,13-15 (usually 14); anal fin II,14-17 (usually 16); pectoral rays 13-14 (14 in only one specimen, and only unilaterally); pelvic fin I, 3; caudal-fin segmented-rays 13. Vertebrae 10 + 21-23 (usually 22). Incisors and canines look very similar, 42-46; posterior canines 4-7 on each side of specimens at least 25 mm SL, 42-46. Lateral line without pores, terminates below dorsal-fin spines 9-11 (usually 10). Anterior nostril with cirrus on posterior rim only. Overall pale to dusky grey with spoke-like markings on iris. Head darker in males, darkest above mid-orbital level; with spot at midpostorbital margin, dusky, may be absent, but may also extend to the opercle as a stripe connecting to the middle body stripe; some with short, diffuse, dusky stripe on opercle; with streaks on ventral surface of head from lower lip to margin of gill opening. Body with three stripes, slender, dark, equally spaced at the pectoral-fin axil region, continuous anteriorly but posteriorly breaks into dashes and spots from the region below segmented-ray portion of dorsal fin; dorsal stripe along the lateral line, middle stripe from head to caudal-fin base as a dark spot, ventral stripe from pectoral-fin axil to caudal peduncle as a dark spot; also with spots, dark, usually 4 or more spots in each "stripe"; some also with bands, faint and dusky, 7-8 along dorsal contour (Ref. 5296, 90102). Body depth 5.3-6.1 in SL, at origin of anal-fin (Ref. 90102).

Oviparous, distinct pairing (Ref. 205).

Dorsal spines (total): 12; Dorsal soft rays (total): 13 - 15; Analspines: 2; Analsoft rays: 14 - 17

Adults are found in coral reefs (Ref. 90102). 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). Minimum depth of 0 m reported from Ref. 5396.

Ecsenius kurti

DESCRIPTION.—Dorsal fin XII,13–15 (modally 14). Anal fin II, 14–17 (modally 16). Pectoral fin 13 or 14 (14 in only one specimen, and only unilaterally). Segmented caudal-fin rays 13. Vertebrae 10 + 21–23 (modally 22). Dentary incisor teeth (includes anterior canine teeth, which differ little, if at all, in appearance from incisors) 42–46; posterior dentary canines (specimens at least 25 mm SL) 4–7 on each side. Lateral line without pairs of pores, terminating posteriorly at point between verticals from dorsal-fin spine 9 and interspace between spines 10 and 11 (modally reaching vertical from 10). Cirrus present on posterior rim of anterior nostril; none on anterior rim.

Preserved Color: Head variable, generally pale to moderately darkly dusky (darker in males than females), often darkest above mid-orbital level; dusky spot often present at midpostorbital margin, occasionally continuing posteriorly across head, particularly on opercle, as dark or diffuse, faintly dusky stripe, which connects with middle body stripe; some specimens with short, diffuse, dusky stripe on ventral third of opercle; ventral surface of head usually with indications of slender, dark stripe on each side extending posteriorly from just posterior to lower lip and ceasing before reaching margin of gill opening. Body with three slender, dark stripes separated by equal interspaces in region of pectoral-fin axil; stripes continuous anteriorly, changing posteriorly, usually in region below segmented-ray portion of dorsal fin, to dashes, then fine, dark spots (usually 4 or more spots in each “stripe”); dorsal stripe originating in region above anterior, oblique portion of lateral line, proceeding posteriorly along lateral line, and terminating at some point below posterior region of segmented-ray portion of dorsal fin; middle stripe originating as far anteriorly as head and terminating posteriorly as dark spot at caudal-fin base; ventral stripe originating in pectoral-fin axil and ceasing posteriorly as dark spot on caudal peduncle well anterior to caudal-fin base; some specimens exhibited 7 or 8 faintly dusky bands along dorsal body contour, extending ventrally and becoming offset in space between two ventral dark stripes. Dorsal fin: spinous portion with fine melanophores distributed along spines, least dense in interradial membranes closely adjacent to spines, and narrowly along fin base; segmented ray portion with slender, immaculate area (stripe) just above base, from which melanophores extend dorsally along rays, diffusely concentrating ventrally (giving impression of faint suprabasal stripe in males); few melanophores at ray tips (in males). Anal fin generally dusky with pale ray tips; melanophores concentrating in membranes just proximal to ray tips, giving appearance of subdistal stripe. Pectoral fin with melanophores along rays; fleshy base usually with indication of fine, dark stripe at about mid-level. Pelvic fins ranging from immaculate to rays with sparsely distributed melanophores. Caudal-fin dusky basally with rays essentially unmarked except for fine, dusky margin dorsally and ventrally on each ray; membranes of central rays variably dusky, others almost clear.

Ecsenius kurti, Kurt's coralblenny, is a species of combtooth blenny in the genus Ecsenius. It is found in coral reefs in the western Pacific ocean; it is endemic to the Cuyo Islands of the Philippines. It can reach a maximum length of 3.5 centimetres. Blennies in this species feed primarily off of plants, including benthic algae and weeds. The specific name honours Kurt A. Bruwelheide, who was a museum specialist in the Division of Fishes of the National Museum of Natural History (Washington, D.C.), for his work on the early part Springer's revision of the genus Ecsenius and who photographed many of the types of the species Springer described.
