Sharks

Nurse Shark Nurse SharkNurse sharks are cosmopolitan carpet sharks belonging to the family Ginglymostomatidae. Common in shallow, tropical and subtropical waters of the western Atlantic and eastern Pacific, the family comprises three genera each with one species. They are benthic sharks, characterised as being sluggish and docile. Nurse sharks typically attack humans only if directly threatened. The largest species, called simply the nurse shark Ginglymostoma cirratum, may reach a length of 4.3 m; the tawny nurse shark Nebrius ferrugineus is somewhat smaller at 3.2 m, and the short-tailed nurse shark Pseudoginglymostoma brevicaudatum is by far the smallest at just 75 cm in length. The first of the three species may reach a weight of 110 kg. Yellowish to dark brown in colour, nurse sharks have muscular pectoral fins, two spineless dorsal fins (the second of which is smaller) in line with the pelvic and anal fins, and a tail exceeding one quarter the shark's body length.

Shark Drawings Of course, living sharks don't just remain stretched out straight, like a fish at a sea food shop. They wriggle! They bend and bow and arch. And their pectoral and caudal (tail) fins change position as they move. You can add the illusion of liveliness to your shark drawings by modifying the basic method you've already learned. Instead of starting with an oval, start with a sort-of 'bent' oval — a kind of bean-shape. For example, you can bend your 'bean' downward, as shown here. You can extend the lines on either the head or tail end in the same or different directions, as long as the result seems believable. Because sharks have two pectoral fins, you can increase the three-dimensional (3-D) quality of your drawings by showing part of the pectoral on the other side of the body. Try bending your 'bean' upwards and extend the head and tail parts of your shark in a way that makes sense to you. What about the pectoral fins from this angle? If y...
