Sharks aren’t like most bony fish, they don’t have hard bones inside their bodies. Instead, sharks’ bones are made of cartilage (软骨), like the end of your nose. Most fish have scales (鳞) covering their bodies, including sharks. The scales look like lots of little teeth on the ...
Cetacean bodies are streamlined and fusiform (tapering at both ends). They have small lateral eyes, no external ears, laterally flattened forelimbs lacking a flexible elbow and an indistinct neck. Whale bodies are sub-cylindrical except for their tails, which are flattened at the end. ...
auricle. The pinna is made of flexible, foldable cartilage and skin. The pinna has different parts: the tragus, the helix, and the lobule, while the interior has the hollow, cone-like concha. The outer ear extends from the pinna inward to the ear canal and the outer layer of the ...
The researchers focus on children with microtia, a congenital deformity that causes patients’ ears to underdevelop. The condition leaves people with a hooked piece of cartilage and skin on one or both sides of their head, along with a host of hearing issues. Currently, if a microti...
