Etymology: Percarina: Greek, perke = perch + Latin, carina = keel shaped, shell (Ref. 45335).
Eponymy: Count Anatoly Nikolaievich Demidov (Demidoff) (1813–1870) was a Russian diplomat and patron of the arts and sciences. [...] (Ref. 128868), visit book page.

Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 59043)
背的軟條 (總數) : 10 - 13; 臀棘: 2; 臀鰭軟條: 8 - 11; 脊椎骨: 33. Distinguished from Percarina maeotica by its unique character of having scaleless cheek. Differs further by the combination of the following characters: body and fin membranes almost transparent; back milky white without dark spots; 8-9 greyish round or irregularly-shaped blotches along base of dorsal fins (Ref. 59043).
Occurs in groups in fresh and brackish waters with salinities up to 7 ppt, abundant at depths around 5 m over black mud. Feeds predominantly on benthic invertebrates. Spawns in coastal waters close to river mouths, over mud bottom. Spawning occurs in May-June. More or less abundant in lower reaches of rivers and coastal lagoons but increased salinity resulting from reduced flow in all large rivers, which are now dammed, may pose threat to its population (Ref. 59043).
產卵發生於在六月與七月的前半的 Tagarog 的灣的淡化的部分。 產卵的個體移動外海。 沉性卵在軟泥的底部上被直接地存放。 卵是聚集在一起的但是不黏附在底部因為他們變成塗上一層有細小的軟泥粒子。 被花鱸捕食。 稚魚被 chekhon 消費, 成魚被鯰魚消費。 (參考文獻 2058)
