Our idea is simple - learn, shoot, explore. Tweet By Jonathan Lavan The underwater world amazes us as photographers. Part of being a good underwater photographer is being able to identify the fish and other creatures you're looking at.
Knowing where to likely find their habitat, how creatures interact with each other and whether their behavior is unusual or not could be the difference between a good shot and a great shot. Sea creatures have some amazing adaptions for survival. For more underwater photos, follow us on Instagram! Many bony fish have more than just one set of nostrils.
The nostrils of fish also do not open into the back of the mouth like those of mammals, and are not, therefore, for breathing.
They lead into organs of smell, which are very sensitive in order for fish to detect the presence of food in the water at considerable distances. Not all Hermit Crabs use discarded seashells as their portable shelters. In the Sea of Cortez some hermit crabs use living, growing Hydrocoral and others, in the Indo-Pacific region, live in the fixed wormholes left by marine worms.
Sharks are covered with tiny little teeth called dermal denticles. Damselfish are farmers growing little algae gardens. Moray Eels open and close their mouths, not as an aggressive behavior but as part of their respiration process.

Boxfish do not have a conventional bony skeleton like most vertebrate. They literally have a bone box that only the eyes, mouth and fins stick out of.
Many species of fish are hermaphrodites. They will start their lives as females and then if a male is needed the lead female will become a male.
Barnacles are actually crustaceans related to crabs and lobsters. Since they are fixed to the substrate the male barnacle must use a very long reproductive part to be able to reach his mate!

Equivalence relates the visual properties of photos from different formats based on the focal length and aperture of the lens.
