Product Description

When alive, Pikaia was a compressed, leaf-shaped animal.
It swam by throwing its body into a series of S-shaped, zigzag curves, similar to the movement of eels.
Fish inherited the same swimming movement, but they generally have stiffer backbones.
Pikaia had a pair of large head tentacles and a series of short appendages, which may be linked to gill slits, on either side of its head.
In these ways, it differs from the living lancelet.
