[Note Guidelines] Photographer's Note
Predatory animals inspire a sense of awe, respect and fear among humans. On land, big cats, wolves, and bears are some of the quintessential predators. Dip beneath the waves, however, and sharks take the stage, alongside orcas, sperm whales, and large squids and fishes. Although there are many marine predators, it is the sharks that have been most stereotyped as the "killers from the deep".

There's no denying the fact that sharks are carnivorous and predatory. Generally, however, sharks have a more diverse diet than usually credited by the general public. The giant filter-feeding basking shark (Cetorhinus maximus) is inclined to consume copepods of the genus Calanus. The whale shark (Rhincodon typus), another very large filter-feeder (see link on this species below), also feeds on zooplankton, although it is not averse to taking small- to medium-sized fishes swept up in its enormous maw. Some sharks concentrate mainly on certain types of prey, such as cephalopods (squids and octopuses); crustaceans (lobsters, shrimps, etc.); shellfish, or small fishes, whereas others will take prey from any of these groups. Many sharks are oppurtunistic, meaning they will feed on most edible items they encounter.

Whatever their dietary preference, sharks are well-adapted to deal with their prey type. Many bottom-dwelling sharks, such as the orectolobiformes (including the nurse sharks) and heterodontiformes (such as the Port Jackson shark [Heterodontus portjacksoni]) have flattened molar-like teeth and strong jaw muscles, all the better to crush the shells of their common prey, molluscs and crustaceans. Another, better known, example of dietary adaptation is the infamous white shark...

Excellent capture with pleasant frame and POV of this great marine predator.
Very good colorful and sharpness with excellent content in your notes.

Very intresting broad ranging note, a good defence of the much malined shark.
Intresing shot from below it looks to be a good clear shot. Are the bubbles yours?

tres jolie photo sous-marine !
les details sont tres bien retranscrit, notament sur l'oeil et les ouies :)
Good work.

Yes, it is a nice and clear shot. Alas I to wonder on the shooting conditions.

Great shot how did you take it?

Paolo, Unique presentation with great notes. Wonderful perspective on the shot. Just wondered when & where this was taken? Great post! Points later...

what equipment did you use to take this pic, and where abouts was this taken. interesting.

Wonderful shot and POV... were you diving when you took this shot? Also I am interested to know what camera/lens//so forth you used for this great image.

Just very recently we had a 1200# female Great White Shark stuck in a cove down on Cape Cod here in the US. She stayed with us for a couple of weeks until marine biologists could finally get her to move back into open waters. She was HUGE!

Nice sharpness. Nice blues! The problem with your photo are two: the POV, because the shark is going too much from your lens; and the image, because that bubbles from some of yours buddies have not to be there. Anyway, it seems like a great dive and your photo is a wonderful souvenir. Tfs!

More information on the way the photo was taken would have been nice. But a rare colorful shot!
