“The harp seal or saddleback seal is a species of earless seal native to the northernmost Atlantic Ocean and adjacent parts of the Arctic Ocean. Newborn pups weigh around 11 kilograms (24 lb) and are 80–85 centimetres (31–33 in) long. After birth, the mother only feeds that pup. During the 12 day nursing period, the mother does not eat, losing up to 3 kilograms (7 lb) per day. Harp seal milk contains up to 48% fat, so pups gain over 2.2 kilograms (4.9 lb) per day. During this time, the juvenile's “greycoat” grows in beneath the white neonatal coat, and it weighs 80 pounds (36 kg)”. – Wikipedia

“Emmy” award-winning cinematographer, Shawn Heinrichs teamed up with model and diver Hannah Fraser to carry out a unique underwater conservation fashion shoot in a remote location in the South Pacific Ocean. The pair are aiming to raise awareness for the plight of the marine mammals at the hands of whalers. During the ten day shoot Fraser swam and glided with pilot and humpback whales.

With the humpback calving season drawing to a close, here’s a look at some of Rita Kluge’s distinctive marine photos from the south Pacific. The Sydney-based photographer fell in love with whales after witnessing southern rights from the New South Wales coastline as they travelled to and from their feeding grounds in the Antarctic. She has since been to Tonga, where humpbacks breed and calf in winter months, to photograph them in the water. (Photo by Rita Kluge/The Guardian)

This diver almost got sucked into the mouth of a massive whale shark as it feeds on plankton. But far from staring into the jaws of death – the shark, which are the sea's largest fish, is actually vegetarian. The relieved diver escaped from the encounter unscathed and continued to enjoy the presence of the incredibly docile animals. The stunning photograph, by Mauricio Handler, was taken during a feeding session where more than 600 of the huge creatures gathered to feed on tuna spawn. (Photo by Mauricio Handler/Daily Mail/Solent)
