Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 7; Rückenflossenweichstrahlen (insgesamt) : 17; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 18. This species is distinguished by the following characters: D VI-I, 17; A I, 18; pectoral rays 18; scales in longitudinal series 78; scales absent on head, nape, or prepectoral area; body elongate, its depth 6.6 in SL; dorsal spines progressively longer to fourth, 4.05 in SL; caudal fin pointed and moderately long, 3.0 in SL; pectoral fins reaching to above anus, 3.8 in SL; pelvic fins not reaching anus, 4.65 in SL (Ref. 75899); characterized further by male with bluish body color, white abdomen, head and body covered with yellow spots, blue mid-dorsal stripe on head, yellow spotting on dorsal fin; female similar to male except for having irregular dark spots on first dorsal fin and yellow streaks instead of spotting; united pelvic fins, presence of well developed frenum; body covered with cycloid scales anteriorly, ctenoid posteriorly (Ref. 90102).
The alpheid Alpheus cf rapacida is the symbiotic snapping shrimp that shares the burrows with this species in both Papua New Guinea and Majuro (Ref. 78591). Found in estuaries, lagoons and sheltered reefs (Ref 90102).
