背的軟條 (總數): 68-80; 臀鰭軟條: 51 - 59; 脊椎骨: 39 - 43. This species is characterized by the following: vertebrae 11-12 + 27-31 = 39-43, dorsal fin rays 68-80, anal fin rays 51-59; outer pseudoclasper with a broad base and long supporter with sharp, pointed tip; inner pseudoclasper is anteriorly inclined, of about length of outer pseudoclasper, with sharp, spine-like tip anteriorly and fleshy flap posteriorly; isthmus between pseudoclaspers wide, penis with abrupt change in thickness; opercular spine with a single, sharp tip; cheeks naked or with few isolated scales (less than 10 scales all together); otolith length: height ratio 2.1-2.2; upper preopercular pore absent (Ref. 57883).
這種特徵為那在:之後 脊椎骨 11-12+27-31=39-43 ,背鰭鰭條 68-80, 臀鰭棘條 51-59; 外部的 pseudoclasper 具有一個寬的基底,而且長的支持者具有銳利的, 尖的頂端; 內部的 pseudoclasper 前面地被傾向,大約外部 pseudoclasper 的長度,具有銳利的, 像棘一樣的頂端前面地與在後部地的肉質鰓蓋; 在 pseudoclaspers 之間的峽部寬的, 用在厚度方面的突然改變的陽物; 鰓蓋棘具有一個單個,銳利的頂端; 頰裸露的或有些孤立的鱗片;(少於 10個鱗片一起) 耳石長度: 高度比 2.1-2.2; 上面的前鰓蓋骨孔不存在。 (參考文獻 57883)
Inhabits rocky crevices (Ref. 11482). Two paratypes that were collected at low tide between blocks of lava in about 50 cm of water, were observed to move slowly close to the sand bottom. Experiments that were carried out showed that O. deroyi can tolerate a wide
variation in salinity, but not the low salinity in which O. galapagosensis lives. Consequently, there is an ecological barrier separating the two species. Only about five embryos were observed in ripe females (Ref. 57883).
棲息於岩石的裂隙。 (參考文獻 11482) 二個在大約水的 50 公分中被在熔岩的塊石之間的低潮採集到的副模式, 被觀察移動得慢慢接近砂質底部。 實驗哪一是成功完成顯示 O. deroyi 能容忍一寬的
鹽度的變化, 但是不是 O. galapagosensis 居住的低的鹽度。 結果, 有一個生態學的障礙分開兩者種。 只有大約五個胚胎在成熟的雌性被觀察。 (參考文獻 57883)
