Before recent storms roiled the Pacific Ocean, conditions were calm and people were able to observe California Sea Lions rafting up and down the Mendonoma Coast. Sea Lions join together in a raft for protection as they sleep. Alan Reinke photographed a large raft recently.

They extend a flipper out of the water to warm it. The warmth is then sent to their internal organs, helping to regulate their body temperature. In hot weather they will do this to cool themselves down.

Thanks to Alan for allowing me to share his photo with you here! If you'd like to see a close-up photo of a Sea Lion with her pup, here is the link: http://www.mendonomasightings.com/2011/06/05/california-sea-lions-photographed-on-the-rocks-off-the-mendonoma-coast/

The coast is alive with the sounds of California Sea Lions. In the calm air, their barking calls can be heard for several miles. Juvenile male Sea Lions have recently returned to the Mendonoma Coast. And they are forming rafts in groups of twenty or more. This has been seen off of Anchor Bay, The Sea Ranch and Timber Cove. They roll to one side and hold a flipper up in the air. This helps to regulate their bodies temperature.

Barbara Rice used her camera and her scope to digascope this photo of a raft of Sea Lions with a Gray Whale spouting just behind. Many thanks go to Barbara for allowing me to share this unique photo with you here.

Bull Kelp, Nereocystis leutkeana, grows as forests in the Pacific Ocean off the Mendocino and Sonoma Coast. Right now the waters close to shore are showing healthy forests. Bull Kelp is an annual and its growth rate is phenomenal. Winter storms will rip the holdfasts from the ocean floor and waves will fling many onto beaches. Once Rick and I went to Bowling Ball Beach after a big storm. There in the mounds of kelp were many beautiful abalone shells - a gift from Mother Nature!

Kelp needs nutrient rich waters to grow. The upwelling that occurs here is necessary for the Kelp's growth. Many creatures depend on this plant. Small fish hide in the kelp from bigger ones. Seabirds have been seen to rest on the surface mats. It's believed CA Sea Lions and Harbor Seals feed on it. And it's known that Sea Urchins feed on it.

Tomorrow I will show you a cute photo of Harbor Seals draped in kelp and you will read about what is it like to dive amongst kelp.

On calm days the Sea Lions on the colony at Fish Rocks just off of the hamlet of Anchor Bay can be heard noisely barking. They are giving birth to pups now on the rocky islands off the coast. Craig Tooley captured a photo of a mom and her newborn pup and has kindly allowed me to share it here. Another of Craig's photos shows a group of Sea Lions on Fish Rocks. They are known for their intelligence and playfulness - this mammal is often the trained "seal" found in zoos. I prefer to view - and listen - to them in the wild!
