this class refers to the mereological sum of digastric muscles in an organism (typically two).
The digastric muscle (also digastricus) (named digastric as it has two bellies) is a small muscle located under the jaw. It lies below the body of the mandible, and extends, in a curved form, from the mastoid process to the symphysis menti. It belongs to the suprahyoid muscles group. A broad aponeurotic layer is given off from the tendon of the digastricus on either side, to be attached to body and greater cornu of the hyoid bone; this is termed the suprahyoid aponeurosis.

In most mammals there is a common tendon between the ant. and post. muscles, which also makes a connection to the hyoid apparatus, and then the other attachment is to the base of the cranium
