Cooler water

We only had a couple of dolphins visit the boat yesterday near Cordell Bank.  But the sighting is notable as they were Pacific White-sided Dolphins (Lagenorhynchus obliquidens).  

I don't get out on pelagic trips that often, but during the last two years, while ocean temperatures were warmer, I only saw Common Dolphins (Delphinus spp.).  With cooler water temperatures this year, perhaps the species have shifted back to the more expected dolphin for this area.

For the record, here's a documentary shot of a Pacific White-sided Dolphin from yesterday:



And a better shot from a trip in October 2011:
