Almost all animals have symmetrical bodies. Bilateral symmetry is almost universal in all animals and is only very rarely ...

The favoured direction of the cichlid's attack corresponds to its laterally asymmetric head shape: It prefers to attack the prey fish either from the right or from the left side, depending on the ...

Microscopic fossils found in China emerge as the oldest examples of animals that display bilateral symmetry -- two halves that are mirror images of each other. The find by a USC paleontologist and ...

Fossils of the bilaterian Ikaria wariootia found in South Australia represent one of the oldest examples of an organism with anterior and posterior differentiation, according to a study. During ...

Bilaterians are animals that exhibit bilateral symmetry, meaning their bodies have two symmetrical halves, each mirroring the other. This structure includes distinct head, tail, back, and belly ...

Animals with bilateral symmetry, like humans, have bodies specialized to move in one direction — forward. Many animals with radial symmetry don't move or do so slowly.

One major division of the kingdom Animalia is Cnidarians (animals built around a central point) and bilaterians (animals with bilateral symmetry), which includes us humans. A new study found that ...
