Running symmetrically along each side of the fish's body, the lateral line is more or less visible, according to the species. It consists of a succession of pores that communicate with a canal situated under the skin.
Axis - Lines around which a 3-dimensional body are symmetrical.
Basal - Of, relating to, or forming a base.
Bifacial - Corallites occur on both sides of a plate or frond.
Bifurcate - Divided into 2 equal branches.
Normal swimming is largely by the transparent pectoral fins, with extra guidance and a bit of drive by their symmetrically positioned dorsal and anal fins.
The main distinction between the two puffers is the Carinotetraodon having a speckled coloration, while the travancoricus exhhibits a spotted, almost symmetrical pattern. (IMHO, the difference in body type is somewhat akin to the differences in T.

Commonly known as "mermaid's parasol," plants in this genus are radially symmetrical. Biflagellate gametes arise from liberated cysts. Zygotes become attached to calcareous substrates and differentiate slowly.
The body of Planaria is non-segmented and bilaterally symmetrical. The head is triangular shaped and contains two eyespots that detect light.
lack of elongate, symphyseal teeth on the dentary, a reduced lateral line extending posteriorly onto at least the caudal peduncle, presence of teeth on vomer, dorsal fin with 5 or 6 segmented rays and with first ray spinous basally, symmetrical, ...
It's hard at first, but these fish must be destroyed. Any fish that exhibit bad fins, unsymmetrical bodies, swimming problems or missing body parts should not be kept in the hobby. These fish would never survive in the wild........!!!! ...
Also called the Blotched Foxface, the One Spot Foxface is extremely similar in appearance to the Foxface Lo, except for the aforementioned spot. Natural variation of this dark spot can range from an almost symmetrical circle to a "free-formed" ...
