External anatomy of the dogfish shark. The line is made up of a series of tiny pores that lead to receptors that are sensitive to the mechanical movement of water and sudden changes of pressure.

Nostrils and sense of smell the nostrils of a shark are and external part of the shark anatomy and on the ventral side of their bodies.

External shark anatomy. The shark anatomy allows them to see in dim light they can detect the contrasts of light and shadow and their pupils can dilate and contract. Scales embedded in the skin provides shark with rough texture consist of two openings incurrent and excurrent separated by ram jet ventilation and feeding. The diagram above does not represent any one species of shark but rather is a compilation of the features posessed by many different species.

External shark anatomy lets have a closer look at what makes shark anatomy so amazing. We think this is the most useful anatomy picture that you need. Water exits through external gill slits.

The anatomy of a shark resembles the design of an airplane. Labial groove and pouch found skinplacoid scalesdermal denticles scales embedded in the skin provides shark with rough texture nares consist of two openings. These organs have tiny hairs that bend when an an imal moves near the shark.

Located between the mouth and pectoral fins there are five on each side. Sharks have no external ear flaps but have two small pores on the top of their heads that connect to inner ear ducts. The spiny dogfish has a double dorsal fin.

Two fins located on the dorsal side of the dogfish cranial and caudal. Caudal keel the caudal keel is present in some species of shark and helps to strengthen the caudal peduncle or tail base as well as streamlining the shark for easier movement through the water. They have a tail and the wings to help balance everything and to give it speed and while there is no evidence that the dynamic design of airplanes came from the shark anatomy it does make sense.

The external anatomy of a shark the external anatomy of sharks varies considerably between the approximately 370 known species. Each dorsal fin includes a large spine preceding it that serves as a defensive structure. The inner ears of sharks consist of three fluid filled semicircular canals and three otolith ear bone organs.

The anterior dorsal fin is larger than the posterior dorsal fin.
