First - my thanks for all your generous crits and sorry mine have been shorter than usual - I have been rather busy and am having trouble keeping up.

This shot was taken around the Banks Peninsula near Christchurh, which is a hotspot for these dolphins.

At an average length of just 1.3m, Hector’s dolphin (Cephalorhynchus hectori) is the smallest marine dolphin in the world. Unfortunately, with an estimated total population of between 3,000 and 4,000, it is also one of the rarest and is classified as endangered by the IUCN. Found exclusively in the coastal waters of New Zealand, Hector’s dolphins are generally encountered within a few nautical miles of the shore, and are easily recognised by their distinctive rounded dorsal fins, which have been likened to ‘Mickey Mouse’ ears! While Hector’s dolphins are observed around both the North and South Islands, at least four distinct sub-populations have been identified through genetic evidence from mtDNA research and from distribution studies. The North Island population is now thought to be as small as 100 and is restricted to a small section of the West Coast, earning it the unfortunate distinction of being classified as critically endangered.

While there are several factors that may be causing the decline of this species, such as pollution and boat strikes, the main factor seems to be incidental catch in gillnet fisheries. In the mid 1980s, up to 50 dolphins per year were being caught along the Canterbury coast alone (a 250km length of the east coast of the South Island). Such a high level of bycatch was certainly unsustainable, given that Hector’s dolphin populations, like other dolphin species, have a maximum potential growth rate of 2-4% per annum. This, together with a low overall abundance and a rather patchy distribution, prompted the Department of Conservation to establish New Zealand’s first marine mammal sanctuary, in the waters around Banks Peninsula in 1988.

Hi James, definitly one of the highlights of my visit to NZ, BUT I never managed to get them on film. Here's a great picture, because I know how hard it is to get a picture of a dolphin. Good work,
JAcob

You are very lucky to see such a cool but rare animal James and then photograph it brilliantly as well!
Impeccable timing to capture this breaching Dolpin.
We get a real sense of its speed from the water spray and dynamic composition.
Superb sharpness and clarity.
Informative notes.
Very, very well done!

Cheers,
Joe

Hi James,
A nice capture of this beautiful Hector Dolphin. Well composed with very good details and a good DOF. Thanks a lot for sharing.

Nice shot. Good use of thirds and you've stopped the action of the water droplets perfectly.
