Mother and Calf are bonding near the water surface..

Humpback whales are not thought to make lifelong bonds and are thought to be promiscuous breeders - the mother and calf relationship is the exception. A calf can remain with the mother for up to a year. This picture was taken in the Silver Bank Marine Sanctuary: a key calving and nursing ground for these majestic animals in the Dominican Republic. The gestation period about 12 months and when a baby humpback is born it is 12-14 feet in length weighing 1 to 1.5 tons. The calf in the picture is about two months old and growing fast. We watched from a distance whilst the calf moved up and down in 3-5min breathing cycles very close to its mother who never let it stray more than a body length away. After much patience she allowed us to get closer.

Scuba diving at Princess Alice Bank (Azores Islands, Portugal) with lots of giant devil rays (Mobula Mobular). Princess Alice Bank is a submerged mountain that comes from a depth of more than 1000 m up to 32 m and is a world famous dive site for experienced divers.

Oceanic White Tip Shark from maya de almeida on Vimeo.

The oceanic whitetip shark, Carcharhinus longimanus, is a large pelagic shark inhabiting tropical and warm temperate seas. Its stocky body is most notable for its long, white-tipped, rounded fins. The oceanic whitetip is found globally in deep, open water, with a temperature greater than 18 °C (64 °F)
This aggressive but slow-moving fish dominates feeding frenzies, and is a danger to shipwreck or air crash survivors. Recent studies show steeply declining populations because its large fins are highly valued as the chief ingredient of shark fin soup and, as with other shark species, the whitetip faces mounting fishing pressure throughout its range.

When the males arrive, their testosterone levels are high and they are eager to find a mate. The presence of a receptive female can lead to competitive rowdy groups as challenging males physically struggle to displace her escort.

These conflicts can be very physical, last for hours, and cover many miles as each bull fights for the favored position at the female's side. Being on the water in a small boat when four to fifteen (or more!) male humpback whales brawl for dominance is quite a spectacle..
