Firm, rubbery matrix is a structural feature of which connective tissue type?

Connective tissues are the tissues that are responsible to connect, support, bind, or to separate out other tissues or organs,that have relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, that includes cartilaginous, fatty, and elastic tissues. Cartilaginous tissues are responsible for the firm, rubbery matrix that provides flexibility. These tissues give shape to the external ear, the larynx  (voice box) which is the most easily palpated cartilages in the body, and to the tip of the nose.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
