Are Chimaeras Bilaterally Flattened?

The chimaeras' closest living relatives are sharks, even though they branched off from them nearly 400 million years ago. ... In cartilaginous fish, the skeletons are composed of cartilage. > Bilaterally Flattened - Bony fish

Bony fish
Bony fishes, class Osteichthyes, are characterised by bony skeleton rather than cartilage. They appeared in the late Silurian, about 419 million years ago. The recent discovery of Entelognathus strongly suggests that bony fishes (and possibly cartilaginous fishes, via acanthodians) evolved from early placoderms.

are flattened on both the left and right sides, forming mirror images on their two sides.

Which fish is bilaterally flattened?

Bilaterally Flattened - Bony fish are flattened on both the left and right sides, forming mirror images on their two sides. Most cartilaginous fish are flattened on the bottom, creating two distinct sides - a flat white bottom, where the gills are, and a top with color, where the fins and eyes are.

Are skate bilaterally flattened?

Sharks, skates, and rays have a well-developed electrosense that presents strikingly unique morphologies. Here, we model the dynamics of the peripheral electrosensory system of the skate, a dorsally flattened batoid, moving near an electric dipole source (e.g., a prey organism).
