Nice!!! That's a great find to come across right off the bat! So cool!!! Is it a Octopus bimaculoides??? ...which are my favorite cephalopod found in that area!
Yesterday we all headed down to the rocky intertidal shore at Vina Del Mar to go tide pooling. The rocks were massive and considerably difficult to traverse. I think everybody fell at least once. No major injuries though! We worked our way to the rocks just in front of the water first, in order to get a chance of seeing that area before the tide started to come in and cover it up. We found a wide array of organisms, including swimming crabs, porcelain crabs, hermit crabs, turban snails, blennies, brittle stars, sunstars, sea urchins, two-spotted octopus, sea urchins, sea cucumbers, anemones, isopods, chiton, etc. My personal favorites were the brittle stars and the marine isopod. Brittle stars are in the Phylum Echinodermata, which also includes sea stars, sea urchins, sea cucumbers, and sand dollars. Some characteristics of Echinoderms are their radial symmetry (except in larval stages), water vascular system, and calcium carbonate endoskeleton. This brittle star in particular was a s...
How can one week feel so long, yet not be enough? I could have lived at CEDO with you guys all summer. Thank you so much to Paloma, Eleazar, Mariel, Angeles, and all of the other staff for making our stay an absolute dream. I had never been out of the country before this trip, and now I want to visit absolutely everywhere. We wrapped up our week at CEDO by doing a service project where we pruned bushes, cleaned signs, sorted trash, cleaned the fish tank and fish pond, and shoveled the sand off of the walkway. Liza and I were assigned to the sand shoveling, and we were quickly reminded of how heavy sand is. We had a leaf blower that was our saving grace, but the battery died very quickly. 😔 Everyone else came to help us after they were done with their own tasks, so it became much more manageable. The walkway was unrecognizable when we were done. (I didn't even realize there was concrete under there before because of how much sand there was) After we were done with the service proje...
On Thursday (5/15) we split the group up and took two boats to Bird Island (Isla San Jorge). It's approximately 28 miles from the coast of Puerto Peñasco, which meant an hour and a half long boat ride for us. Our main goal of the day was to swim with the sea lions and complete a census for CEDO. We tried on our wetsuits (provided by CEDO) the day before, which was quite a harrowing task. Most of us had never tried on a wetsuit, so we were very surprised to find out how difficult they are to put on. (And take off) We felt like arthropods molting when it was time to take off our wetsuits. Once we got close to bird island, we understood where the name comes from. The island was flocked with birds, mainly the brown-footed and blue-footed boobies. We also saw some seagulls, cormorants, red-billed tropic birds, and pelicans. Once we arrived at the island and anchored our boats, we saw the hundreds of sea lions that inhabit the island and the surrounding waters. Sea lions are in the Phylu...

Yes! All two-spotted octopus so far. Hopefully we will see some other octopus species tomorrow.
DeleteI am guessing Whitney's cephalopod seeking super powers are in action!
ReplyDeleteI’ve found four so far, and most of them have greeted me with ink!
