Last week I was able to get away for a quick overnight camping trip and since I went by one of my favorite docks, I had to stop and see what was around. There are many organisms which are always there when dockfouling, but many others are seasonal and nudibranchs are no exception. As I crawled along the many docks, it was quickly apparent that this is Shaggy Mouse (Aeolidia papillosa) season. They were on every dock I checked and not only that, but most of them were with eggs. In some places I found several groups of eggs together. I also found a few Thick-horned Nudibranchs (Hermissenda crassicornis) and a single White & Orange Tipped Nudibranch (Antiopella fusca).
