I went on a mini-vacation to Carmel this week (we’re on break), and insisted to my parents that we go to the beaches so I could finally have an excuse to get my feet wet…for science!
Here’s some of the scenery from Pebble Beach. I saw a bounty of marine life in the water; sea snail, hermit crabs, fish, sea anemones. It was all very colorful and very lively:
I scooped some sea water in a small water bottle and used my Foldscope kit (tweezers, tape, hole punch, paper slides, coverslips, imaging station) to take some shots on site. Here’s me sitting on a ledge trying to make a wet mount on my knee. I used the slide design I thought of last time, with the coverslips sandwiching a paper slide taped with double-stick tape on both sides (it creates a tiny well that won’t squish the organisms).
I found a krill/shrimp, but unfortunately killed it in death-by-squish while transferring it onto my slide:
I have to say, it’s really hard making slides in the field (especially since I forgot to bring scissors and a pipette). I decided to take my sample 80 miles back home and spent the next day at my table imaging.
These are what my slides looked like:
I found some amazing organisms that I can’t specifically identify. In laymen’s terms, here’s some moss growth with a developing shrimp/krill/prawn zooming about.
Here’s a video of this organism swimming around the slide. Any advice on how to suspend samples in order to slow down movements? Scroll to 1:45 to see a good image of the organism.
After, I looked into my magical water bottle of microorganisms.
I found another shrimp/krill/prawn that looked slightly different. It had a longer and more pink/coral body. I didn’t see the forked tail that I saw on the first shrimp/krill prawn and its swimming form was different (more lateral/sideways).
Scroll to 1:45 in the next video to see a good shot of this organism:
Lastly, I found a snail and filmed its contractions! I saw a shell in one of the marine plants and decided to image it for fun. Only when I looked at the shell under the Foldscope did I realize that there was a living sea snail inside the shell. It was awesome getting to see the foot move, and there may be a parasite-like organism attached to the foot (I’m not sure. What do you think?).
Needless to say, I found a lot of amazing organisms on my trip. Any thoughts?
