This picture of the Oceanic Whitetip shark with tropical fish swimming gracefully around it with a solid background makes for a great composition. It is very plain, yet interesting. The fish almost look like silhouettes, while the shark is clearly not.
The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales are found in all oceans, from Arctic and Antarctic regions to tropical seas.
