Photographing Harbor seals in the Kenai Fjords.

Another fun time in Alaska was taking a boat from Seward into the Kenai Peninsula. There were many glaciers in the area so it was common to see ice floating on the water. The Harbor seals take advantage of the floating bergs for a place to rest, protected from sharks and Orcas.

Harbor seals are the most widely distributed of all pinnipeds (walruses, eared seals, and true seals). In fact they are often referred to as common seals. Adult males reach a length of around 6 feet and will typically weigh just under 300 pounds. Females give birth to a single pup which she will raise without the help of the male. The pups are able to swim soon after they are born and grow quickly thanks to the mothers rich milk.

Harbor seals are fish eaters and are not too specific as to what species they will feed on. They can dive for over ten minutes and have been known to reach depths of about 1500 feet. Most dives are shorter and may only reach a depth of around 60 feet. 

As you can see from these photos, they can vary in color from dark brown to a tan and are covered with spot patterns that can be used to identify individuals. Females can live for up to 35 years while the males usually die before they reach 25. Currently there numbers are estimated at around 6 million world wide. As you can see, they are not in any trouble in most areas.

We had a small chartered boat so we were able to move around freely. This allowed me to have a choice between a light or medium background. Depending on whether the water was reflecting the blue sky or a white cloud. The water was very calm on this particular day, allowing me to use a tripod from the boat. I was always careful to ask the captain to shut down the engine for each exposure as the vibration would have created unsharp images.

Let me know what you think.

Let me introduce you to one of my favorite animals, the northern elephant seal

The Northern Elephant Seal is the largest member of the order Carnivora.  Males can grow to be over 20 feet long and weigh in excess of 10,000 pounds.  They are also the deepest divers of all air-breathing animals.  They have been documented to dive to depths of over 7800 feet below the oceans surface.  In order to accomplish this, they have developed the ability to hold their breath for over 100 minutes.



Elephant seals have physiological and anatomical adaptations that enable them to store oxygen for these long dives.  They have a much larger quantity of blood than can be stored in their arteries and veins.  This extra blood is oxygenated and stored in sinuses located in the seals abdomen.  When their body is in need of the extra oxygen, the stored blood is released into the blood stream and pumped to the muscles and tissues.



Elephant seals also have a compound in their muscles called myoglobin that allows the muscle cells to store extra oxygen.



Twice a year Elephant seals haul their huge bodies out of the ocean and onto the beach in order to breed and shed their old skin.  The skin actually dies as a result of being denied sufficient oxygen during long dives.  During these times the males have no chance to eat. Since most of their water is metabolized from the food they eat, they must conserve all the moisture that they can in their bodies.



The large trunk on the males actually serves to recycle the moisture from their breath as they exhale.  This moisture is captured in sinuses within the trunk and is reintroduced into the animals body.  All-in-all, a pretty amazing creature.



The molt is a great time to photograph these huge creatures.  I recommend going to Cambria, California in early June and spending some time on the beach near San Simeon.  There is a large colony there and the action continues all day long.  The angle of the sun is best in the morning as it will be over your shoulder instead of in your face.
