since it's been awhile since I was active, I don't think I posted my first enteromorpha-eating sapsucker found during a sea slug bioblitz for @calacademy.bsky.social back in may 🌿🌊🦑🐙🌎

for weeks, I've been watching the western gull chicks around town growing up on roof tops, dilapidated boats, & breakwater walls but it's fledging time & soon there will be no more cute chick calls to greet me in the morning 🌿🌊🪶

sorry I haven't been super active on this account in awhile, it's been a rough & busy 2026 for me but my friend Nick Ta of @reefrenders.bsky.social asked me to paint his 3D printed sunflower star & california sea hare models for an exhibit he designed & the models recently came home with me ❤️ 🌿🌊🐙🦑
my 3D printed and painted California sea hare model hanging on a picture frame with an image of a scuba diver taking a picture of a real California sea hare in the wild with a descriptive label on the framemy model on it's frame surrounded by artwork and posters of sea slugs including one of California sea hare and their role as model organisms in neuroscience

it was wild moving to california & learning that many of the monarch butterflies migrate east to west, not north to south like they do east of the sierra nevadas this is a cluster of overwintering monarchs on a eucalyptus in pacific grove's monarch sanctuary (sorry it's backlit, early morning) 🌿🐛🦋

This is a nudibranch, or sea slug. I love finding them when I’m scuba diving and taking pictures of them as well. Always fun subjects for macro photography. If it’s Monday…it’s Macro Monday.

Some #nudibranch from 04/05! The new to me ones were the Stubby Dendronotid (first one) and the Hammerhead Doto, which I haven’t included here because this little dude is the size of a grain of rice and my camera just isn’t that good. Other three are Hopkins Rose, San Diego Dorid, and Opalescent.

I caught a pair of velella to show guests on our boat what they look like before they wash up & dry up on the beach, but I think the crew was even more obsessed because they even named them I released the velella back into the ocean at the end of the trip 🌊🐙🦑🌿🌎

✨💜 galaxsea slug 💜✨ We have some lore on the stream about sea slugs - they are actually alien creatures and some of them relocated to the ocean long ago. The ones still in space are galaxy slugs and live on asteroids lol #digitalart #seaslug #galaxyart #art #constellations #pinkleap
A fictional sea slug that looks like it's a glowing blue and purple galaxy with lots of stars and some constellations (with lines connecting the stars together). The background is of space, with some stars and dark purple and blue nebulas.

A three-lined aeolid nudibranch (Orienthella trilineata) found last month during dockfouling in Morro Bay, CA. Perhaps 15 mm long! 🦀🦑📸OlympusTG6
A small sea slug that is clearish white with a median white stripe that forms a Y shape where it extends onto the oral tentacles - these tentacles, and the rhinophores have orange tips. The cerata on the back of the slug are colored like the body but have brilliant orange red tips.
