A Sea Slug by Any Other Name, Guest Post by Robin Agarwal

Acanthodoris lutea nudibranch smells like citrus or cedar

This is the fifth post in our Sea Slug of the Month series by guest author, Robin Agarwal. A Sea Slug by Any Other Name: One Grossly Derivative Title Covering Three Random Thoughts About Scented Sea Slugs, Hopkins’s Rose, and the Ongoing Bother About Names “that which we call a rose By any other name would smell as sweet” —Juliet in Romeo & Juliet, William Shakespeare Although she was not particularly noted for her tidepool explorations, Juliet may have been surprised to discover that three of the nudibranchs (shell-less marine molluscs) living along the Central California Coast actually emit scents …

Field Updates, October 2019: Eelgrass Mapping, Ground-truthing, and Cal Poly Partnerships

Andi, eelgrass technician.

  Eelgrass fieldwork depends on tides Fall is a busy eelgrass season for field staff at the Estuary Program. The exact timing of our field work depends on when the good low-tides occur, which varies slightly from year to year. This year, October had a few days that had tides low enough to expose the eelgrass during daylight hours. This doesn’t always happen—sometimes the low tides we need happen after sundown and before sunrise. We were glad to see good tides in combination with good timing because we have a few different projects going on. Monitoring permanent eelgrass plots First …

Be Sea Otter Savvy 3: More Than Just a Pretty Face

Adult sea otter eats a purple urchin.

This is the third post to our blog series, Be Sea Otter Savvy, written by Gena Bentall, sea otter biologist and Program Coordinator for Sea Otter Savvy. Posts in this series include tips on how to help sea otters thrive and information about sea otters’ behavior, biology, and their role in the estuary and ocean ecosystems. When I was a little girl holding my mom’s hand on the shore in Pacific Grove in 1970, looking out at two sea otters rising and falling on a gentle swell, I knew them only from their faces in books. I knew nothing of …

Family-Friendly Hikes Around Los Osos

    The land that surrounds the Morro Bay estuary is contoured by hills and valleys, studded with trees, and etched by creeks that take their time winding down to the salt marsh and entering bay. In short, it is a beautiful place that offers many opportunities to get outside and explore. But, as temperatures dip and the sun starts to set earlier in the day, many of us spend more time inside than out. Studies show that making time to enjoy the natural spaces around us by hiking, walking, or even just visiting with friends in green spaces can …

The “Smalls”: The Teeniest, Tiniest Sea Slugs In California

Guest post by Robin Agarwal   This is the fourth post in our Sea Slug of the Month series. Find tips for spotting nudibranchs from the comfort of your local dock at the end of this post! So you’ve been tidepooling along your local reefs and you’ve found a few nudibranchs: Opalescents, Sea Lemons, Spanish Shawls, Hopkins’s Rose, Triophas. Maybe you’ve practically tripped over ginormous squishy Sea Hares. Boring, right? What a snooze, all those flamboyant colors, shapes, and bizarre anatomy. After all, those nudibranchs are over an inch long, and therefore way too easy to find.  If this is …

Field Updates September, 2019: Stream Profiling and Bay Monitoring

  Fall is in full effect here on the Central Coast, and we are enjoying the crisp mornings and clear days that go along with it. Fall is typically the slowest time of year for fieldwork so we are mostly catching up on activities back here at the office and planning upcoming projects, but that’s not to say we haven’t been out in the field this month. Thank you, cleanup volunteers! We hope some of you got out this month for Creeks to Coast Cleanup Day, where nearly 2,000 wonderful volunteers picked up about 11,500 pounds of trash from our …

Creeks to Coast Cleanup Success in Morro Bay

    No matter how far inland we live, we’re all connected to the ocean by water. Rain washes downhill and into stormdrains, creeks, and rivers before entering the sea. So, if we’re going to keep plastics, other harmful debris, and pollutants out of the estuary and ocean, we have to start inland. That’s the idea behind the Creeks to Coast cleanup, a set of 49 cleanups organized by local nonprofit ECOSLO. This massive cleanup effort took place last weekend all across San Luis Obispo County on International Coastal Cleanup Day. During the course of three hours,  1,840 volunteers picked …

Cuesta College dives in to help study eelgrass declines in Morro Bay

    A guest post by Dauphiene Parks During June 2019, a group of fourteen spirited Cuesta College Marine Microbiology students came together under the kind and careful guidance of professors Laurie McConnico and Silvio Favoreto. The mission was to explore the Morro Bay Estuary and examine the local eelgrass population. We quickly learned that 97% of the eelgrass in the Morro Bay Estuary has been lost, and that eelgrass habitats can provide an estimated $87,000 in ecosystem services annually. We were excited to be a part of this class that allowed us to earn college credit and work on a …

Find tips for spotting nudibranchs in the intertidal zone at the end of this post!   Spanish Shawl nudibranchs If you live your life in saturated color, this is the sea slug for you.  One of the great treasures of a few hours’ worth of tidepooling along the California Central Coast during the lowest tides of the season is the possibility of seeing multiple species of nudibranchs. Commonly called sea slugs, a term that includes many other families of molluscan cousins, nudibranchs are shell-less marine …
