Black Sea Nettle, Chrysaora Achlyos : Natural History
The black sea nettle is considered a giant jelly; its distinctive purplish bell can reach over three feet (91 cm) in diameter; its lacy, pinkish oral-arms  can reach nearly 20 feet (6 m) in length and its stinging tentacles 25 feet (7.6 m) or more. It probably lives in deeper, calmer waters but has appeared in large blooms  in California coastal waters, most recently in 2010. 

Conservation
Giant black sea nettles appeared in droves along the San Diego shoreline in the summer of 1989. Then they mysteriously disappeared. The giant drifters reappeared again ten years later, in the summer of 1999. Increased numbers of sea nettles may be an indication that human activities have changed the condition of the ocean. Increased organic material means more nutrients. More nutrients, plus fertilizers from farms, enrich the plankton,  providing more food for jellies and allowing them to increase in number.It is likely that the appearance of black sea nettles in coastal California waters is also related to El Nino/La Nina events. 

Cool Facts
The black sea nettle provides the Pacific butterfish with food and protection. The silvery butterfish feeds on the plankton gathered by the jelly, and when danger approaches, the butterfish actually hides inside the jelly’s bell. The black sea nettle is a mysterious creature; during most years its whereabouts are unknown. Scientists just recently named this jelly in 1997, although pictures of the species were taken as early as 1926. Much about its behavior, distribution and life cycle remain a puzzle.

Monterey Bay Aquarium : Exhibits at the Monterey Bay Aquarium

The stunning one-million-gallon Outer Bay exhibit is home to the largest community of open-ocean animals to be found in any aquarium. Giant bluefin tuna power their way through the water. Hammerhead sharks circle inches away. Sea turtles cruise lazily by.

The Outer Bay also features the largest permanent collection of jellyfish species in the United States. Egg-yolk jellies and sea nettles drift gently in ten-foot-long exhibits beautifully lit to accentuate the jellies' delicate beauty. Comb jellies pulse with rainbow bands of light as they swim.

In the past, a wonderful exhibit of Jelly Fish and most recently The Secret Life of Seahorses; always something exciting to see at the Monterey Bay Aquarium.

Purple-Striped Jelly, Chrysaora Colorata : Natural History: Large and striking, adult purple-striped jellies are silvery white with deep-purple bands. In certain seasons, they mysteriously appear near  the shores of Monterey. When the jellies arrive, it's wise to keep your distance (their sting isn't fatal, but it can be painful). Young cancer crabs are often found clinging to this jelly, even inside the gut. The crab helps the jelly by eating the parasitic amphipods that feed on and damage the jelly. 

Conservation: Human activities can hit nearshore habitats hard. Dredging, dumping and silt build-up can wipe out underwater communities in bays, estuaries and reefs. Several jelly species live in nearshore habitats. And many that don't live near the shore do develop in nearshore "nurseries" when they're young. Harming these habitats could reduce the overall jelly population. 

Cool Facts:
The purple-striped jelly’s lifecycle was first discovered in its entirety at the Monterey Bay Aquarium.
How does a jelly move? The bell pulses to move short distances—to go farther a jelly rides the current.
Since divers have seen ocean sunfish eating these jellies, we know some fishes must be immune to the sting.

Ice Storm February 2, 2011 : Not so much winter "fun."  It is beautiful, like an icy wonderland outside.  BUT...  Oh sh*t doesn't even begin to cover it.  I had to AXE my way into the feed shed to feed the horses this morning.  Meanwhile, I hear and see 7 more trees go down in the neighborhood.  Thankfully the horses are all okay.
