Having identical parts on each side of an axis.
Capable of division into symmetrical halves by only one longitudinal plane passing through the axis.
1
Background: Schipperkes develop bilaterally symmetrical alopecia preceded by lightening of the hair coat not associated with systemic clinical signs.
2
The mouth was toothless and the two talons, bilaterally symmetrical about the main body, each had four sharp digits.
3
The principal lesions were severe oedema of the brain and early, bilaterally symmetrical, focal necrosis in the medulla oblongata.
4
These unicells then aggregated to polyps and their relatives, and then to simple, bilaterally symmetrical worms (see Fig.
5
They found that the embryos were bilaterally symmetrical, and were organized so differently that they belonged to two distinct taxonomic groups.
6
During embryogenesis, two bilaterally symmetrical cephalic neurogenic regions form, which are initially separated from each other and from the ventral nerve cord.
7
The thing was both radially and bilaterally symmetrical, with the body knobbly in the middle but coming to a sharp point front and back.
8
Fusion of bilaterally symmetrical organs in the mid line (or fission of singletons into pairs on the antimeres) establishes a major class of cases:
