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.

背的软条 (总数) : 10 - 13; 臀棘: 2; 臀鳍软条: 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).
Body shape (shape guide): fusiform / normal.
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).
产卵发生于在六月与七月的前半的 Tagarog 的湾的淡化的部分。 产卵的个体移动外海。 沉性卵在软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为他们变成涂上一层有细小的软泥粒子。 被花鲈捕食。 稚鱼被 chekhon 消费, 成鱼被鲶鱼消费。 (参考文献 2058)
