Final answer:
The plane that divides an animal into dorsal and ventral portions is the frontal (coronal) plane.
Step-by-step explanation:
A plane that divides an animal into dorsal and ventral portions is known as the frontal (coronal) plane. This plane creates separation between the back (dorsal) and the belly (ventral) of an animal. In contrast to the midsagittal plane, which divides the body into equal right and left halves,
the frontal plane or coronal plane divides the body into front and back portions, while the transverse (horizontal) plane divides the body horizontally into upper and lower parts.
The plane that divides an animal into dorsal and ventral portions is the coronal plane. This plane separates the belly (ventral) or stomach from the back (dorsal), creating front and back portions. It is also known as the frontal plane.
