Deep-sea (Dogfish) Sharks
Deep-sea sharks are small. They swim at depths of 500, 1,000 or more meters below sea level where oxygen is practically nil.

Deep-sea sharks lay eggs. They multiply rapidly and they are far from being an endangered species.

The dogfish shark belongs to the squalidae group and does not have any air bladders. It survive the ocean depths due to its unusually big liver which is 25% of its body weight, with O2 to survive the whirlpools of ocean water where pressure is 10,000 pounds per square inch (psi)

Deep-sea shark liver oil is known to be the only source of pure and genuine squalene, the finest anywhere in the world.

Our squalene is manufactured only from the liver oil of sharks caught in the Philippine deep seas. It is known to be the dietary/food supplement ever discovered for ailing mankind.


Surface Sharks
Surface sharks are big. Some are friendly to man but some are man-eaters like the Great White Sharks.

They cannot go below 200 or more meters underwater. If they do, they will drown or implode due to the intense water pressure.

They give birth to live pups. They never multiply as fast as deep-sea sharks.

They use air bladder to breathe and their liver oil is minimal.

Surface shark liver oil is mostly used as a lubricant or as an ingredient for cosmetic products. It is processed and manufactured, not for human consumption, but for machines, etc.
