In this way, you can create a shark story, establishing its range and in which periods it visits a specific location.

This software can compare your photographs with other database images. By taking a photo of this part of the shark, it is possible to analyze the spot pattern using software on the website (created in the beginning by NASA for the stars and then adapted to whale sharks). Where possible, try to photograph the left side.

That is the part behind the gills and above the pectoral fin. For photo-identification, it’s important to take photographs of a standard zone of the body. Do not point your flash directly into their eyes.ĭid you know that you can identify and distinguish each whale shark? If you look carefully, you will see that the body of this fish is covered by white or grey spots that are unique to each individual, just like our fingerprints. Photographs: Avoid excessive flash photography when photographing whale sharks.It’s important not to restrict their natural behaviour and movements.

If a shark banks (rolls over and presents its back), back away and stop free diving or duck-diving. Approach the whale shark from the side and for the best view of the whale shark in the water swim alongside the shark near its pectoral fins.

  • Snorkel calmly and slowly: Do not chase whale sharks or block their path.
  • If the whale shark comes directly towards you, simply remain calm and split into two groups so that the shark can swim between you.
  • Keep your distance: Stay at least 3 meters (9 ft) away from the head and 4 meters (13 ft) from the tail.
  • Look but don’t touch: Touching whale sharks will stress the animal and normally cause them to dive instantly.
  • Keep your fins under the surface of the water while you are kicking to reduce splash.
  • Keep noise to a minimum: Enter the water by sliding in slowly from the boat feet-first (do not jump).
  • The sharks will often bank and/or dive if snorkelers get too close, ending the encounter for everyone and causing the shark to show unnecessary avoidance behaviour. But it’s important to follow the rules of conduct to avoid disturbing these gentle giants. Often they are indifferent to our presence and the temptation to touch or swim too close is very large. This will, in turn, reveal the shark’s length.Īpproaching these harmless and attractive creatures is not very complicated. Subsequently the distance between the two points highlighted by the laser will be analyzed with the help of software and mathematical formulas. Remaining at a safe distance from the fish, scientists have to point the two lasers at the body of the shark and take photos. The tools are an underwater camera and two parallel laser pointers fitted together at a set distance apart on a single support.

Researchers use a technique called Laser Photogrammetry.
  • Stars in Hollywood: In the last few years, whale sharks have appeared in three international films, Kon Tiki, Life of Pi and Finding Dory.
  • The little ones have a length of approximately 24 inches (60 cm) at birth, and the smallest ever measured was 18 inches (46 cm) long in the Philippines.
  • Baby whale sharks: Pregnant females can potentially contain up to 300 pups.
  • Lower depth limit: More than 6,200 feet (1,900 meters)!.
  • Their head is flattened, they are carnivorous and they feed on zooplankton, small fish and fish eggs, which they filter by opening their mouth wide. On average they are juveniles, from 13 to 26 feet (4 to 8 meters) long. Whale sharks are the biggest fish in the world with a maximum recorded length of almost 65 feet (20 meters), the largest whale shark was measured at 41 feet (12.5 meters), but very rarely can you see sharks so large. (Remember that real whales are mammals and not fish). In fact, in the past they were initially mistaken for whales. Whale sharks are cartilaginous fish that belong to the group of elasmobranchs and have existed for millions of years. Let’s find out a little more about these gentle giants. Harmless and elegant, they swim in the warm waters of our planet in search of tiny food. Mysterious and majestic animals, whale sharks are the largest fish in the world.
