Picture of the week (No.6): Bull shark and Tiger shark.
Each week, Willgoto selects a nice picture and shows it here. Sharks are the theme of the sixth article in this series. This time, by way of exception, two photos have been selected: the bull shark and the tiger shark. Both sharks are unfortunately known for fatal attacks on humans.
The bull shark (Carcharhinus leucas) in Florida.
The tiger shark (Galeocerdo cuvier) in Florida.
Location: The above sharks were photographed in the Atlantic Ocean off the coast of Jupiter Island, a barrier island located about 40 km north of Palm Beach, Florida (USA). Because of the proximity of the Gulf Stream, sharks are abundant and varied on the Atlantic coast of Florida. Experienced divers can watch there different species of sharks, particularly bull sharks, tiger sharks, lemon sharks, hammerhead sharks, and nurse sharks, and even swim with them.

The sharks: The tiger shark is a species which belongs to the largest sharks. The adult generally measures 3 to 4 m (10 to 13 ft) and weighs between 400 and 500 kg (880 - 1100 lbs). The female is usually larger than the male and can measure more than 5 m (16 ft) long. The tiger shark eats virtually everything. It is a superpredator with little consideration about the nature of the food.
The bull shark has also a massive look. However, it is smaller than the tiger shark. The adult typically measures 2m50 to 3 m (8 to 10 ft) and weighs a hundred kg (220 lbs). The female is slightly larger than the male. The diet of the bull shark is quite varied.
Both the tiger shark and the bull shark are found around the world in tropical and subtropical waters. However, in contrast to most other sharks, the bull shark may also swim in freshwater rivers and river mouths. Both species of sharks are classified as near threatened by the IUCN.
The tiger shark and the bull shark are, with the great white shark, the most dangerous to humans. Several deadly attacks have been recorded in recent years, particularly along the coasts of Australia, Brazil and in the Indian Ocean. The bull shark which prefers to swim in shallow waters is mostly supposed to be the author of these bites.

The author of the photos. The author of all above pictures (except those from Australia) is Dirk Wuyts. His web site (http://www.adcdiving.be) is dedicated to photos and travelogues of the ADC scuba Diving Antwerpen - Deurne (diving club and school). The site, in Dutch, contains countless pretty pictures of underwater life in different parts of the world. Many of those photos have been also published in English in our site.
Since we have also published scuba diving photos of other authors, we have made an inventory list of all pictures of the marine life which are available in the different parts of our site. The inventory list sorts the pictures first by species and second by location so that the pictures are very easy to find. Click here and get the inventory list of all our underwater pictures.
