last days

 on Friday in the morning we did a survey of one of the sand dunes in the estuary. we were seeing how many least tern eggs were there as they lay eggs in little depressions in sand they make. they lay one to three eggs. we didn’t see any chicks but we saw some eggs. they blend into the sand very well and you have to be really looking for them.

then yesterday we did a service project where we helped clean the fish tank, trim the plants and clean the signs, and remove sand from some of the walkways. we also did presentations on 3 of the invertebrate phylums. my group did mollusks and i was in charge of the gastropod class of the mollusks. the other groups did arthropods and echinoderms. at night we had a traditional Mexican dinner. it was really good, the sauce that you could put on was really spicy. then we had a fire out font of CEDO and made s'mores. 

this trip was really fun and informative. i learned a lot about many different cool and unique spices of marine life. thank you CEDO for letting us stay and experience the amazing area that is puerto penasco. 

thank you

Tide pooling and Phyla Fun

Image
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...

First Day!

Image
Our journey began yesterday morning when we loaded into the vans and took off from the MCC Red Mountain campus.  We arrived at CEDO yesterday afternoon and settled into our new home for the week. Later that evening, we ventured downtown and had dinner at a restaurant with a scenic view.  Some of the students went down to the shore to do some night tidepooling and saw a few cool organisms. The real fun began this morning, when we went out for our group first tidepooling excursion just a short walk away from CEDO. I'll let the students share what we found 😀. We are planning to finish up our lecture material today so that we can focus on field work the rest of the week--we have a full schedule including tidepooling at rocky shore and sandy habitats, kayaking an estuary, and snorkeling with sea lions! I'm looking forward to the fun-filled week ahead! -Whitney
