Female elephant seals on the beach now are not pregnant. They are skipping this season, for reasons not well understood. Maybe lost last year’s pregnancy. How will they get pregnant this year? I don’t see any mating going on. Alpha bulls have not yet arrived. Elephant Seal mysteries!

Here’s this morning’s King Tide at Piedras Blancas. Sunny. The juvenile seals are okay with being tossed around in the surf. They have migrated at least once and are comfortable under water. Seal pups who will be born in December and January can’t swim, and may drown.

King Tide Thursday and Friday mornings, the highest tides of the year, full moon tonight. The afternoon brings the lowest tides. The north beach at the Piedras Blancas elephant seal viewpoint expands to its widest. The seals are clumped together after the morning’s high water mark.

This sweet young elephant seal, possibly a female, makes her way through the much larger males around her. Notice the cookie cutter shark wound on her side, and the scars on the larger males around she moves over. Cookie cutter sharks leave that distinctive circular wound.

Trump Says America’s Oil Industry Is Cleaner Than Other Countries’. New Data Shows Massive Emissions From Texas Wells.
The oil industry touts Texas as a success story in controlling climate-warming methane emissions. The state’s regulator, however, grants nearly every request to burn or vent gas into the atmosphere.

Two young male elephant seals surf into the beach for the fall haulout. Juvenile seals, those not yet in the breeding population, take a few weeks test on the beach between September and November. The last mature bull left the beach at Piedras Blancas yesterday.

Lazy days of summer! Beach action high points are raising a front flipper to cool off, stretching back flippers, and tossing sand.
One bull still has his brown skin and fur. All the rest have molted to gray. The gray color will turn brown as the hairs grow out and stand up.
