Etymology: Craterocephalus: Greek, krater, -eros = bowl, mixing vessel + Greek, kephale = head (Ref. 45335).
Eponymy: Whitley provided no etymology, but the most likely candidate is his sister Marjorie Clare Frewer née Whitley. (Ref. 128868), visit book page.

简单描述 检索表 | 型态特徵 | 形态测量图
Distinguished from Craterocephalus marianae and Craterocephalus munroi
and all other members of the genus by a combination of the following: head 3.0-3.4 (3.1); greatest body depth 3.6-4.7 (4.1); least body depth 8.8-11.0 00.0); origin of pectoral fin to anus 2.7-3.1 (2.9), all in SL. Dorsal process of premaxilla 1.1-1.70.4 in eye. Midlateral scale count 28-30 (29.1); transverse scale count 5.5-6.5 (6.0); vertebral count 30-32 (31.4). Position of anus in relation to tip of pelvic fin from 0.5 scales in front to 2 scales behind tip of pelvic fin. Differs osteologically from all other Craterocephalus species by a combination of the following: shape of anterior medial process of maxilla; lack of interdorsal pterygiophores (but shared with some other members of C. eyresii group); minute anterior process usually present on cleithrum; dorsal process of cleithrum also present; basisphenoid short and thick. Differs genetically from Craterocephalus marianae at the following loci: ADA, CK, FDP, GPI-l,MPI, PGM and from C. munroi at CK, FDP, GLDH, GPI-l, MPI, PGM. Unique at GPI-lf (Ref. 26703).
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
Lives in clear flowing streams where it is common along the vegetated margin. Generally in shallow water over sandy or gravelly substrates. A shoal-forming species. Capable of multiple spawnings between September and January (with peak activity early in the season). It has reproduced in captivity (Ref. 44894). Feeds mostly on aquatic insects and their larvae, micro-crustaceans, algae and fish eggs (Ref. 44894).
生活在清澈的流动溪流在那里它是普遍沿着长满植物的边缘。 通常在沙或多碎石的底部上的浅水区中。 一个形成浅滩的种。 在九月与一月之间的能够多样的 spawnings.(在季节中初期与高峰活动) 它有在繁殖场繁殖。 (参考文献 44894) 大部份捕食水生昆虫与他们的幼体，细小的甲壳动物，藻类与鱼卵。 (参考文献 44894)
