Scientific Name
Vanderhorstia nannai

Common Name
Moon-spotted shrimp goby

Biology
Dorsal spines (total): 7; Dorsal soft rays (total): 11; Anal spines: 1; Anal soft rays: 11; Vertebrae: 26. Diagnosis: Vanderhorstia nannai shares with Vanderhorstia papillo the elongated 5" (upper lobe) and 9" (lower lobe) branched caudal fin rays. It differs from Vanderhorstia papillo in having more lateral scales (41-45 vs. 27); no scales in the predorsal midline (vs. 11); a unique color pattern (off-white background with large yellow spots along the midlateral body vs. such spots absent, and absence of four dark gray brown saddles on body vs. present); adults with both the third and fourth dorsal spines elongate; more lower gill rakers on the first arch (16-17 vs. 10); fewer pseudobranch filaments (6-7 vs. 9); a single papilla in row c on the cheek (vs. 4) and row b not interrupted (vs. in two sections) (Ref. 53948).
