algae day

We had a fine day of collecting and identifying algae friday. We went to Harry Harris park  in Tavernier and the little ones swam while Superboy did his collecting and sketching and identifications. (He found some good stuff, but not as much as we had hoped. Need to visit more spots next week.)

We also got to examine a moon jelly that had washed up on shore, but silly me forgot the camera so no picture of that.

Superboy did bring some seaweed samples home to take photos to add to his notebook in addition to his sketches:

Here are just a few of the algae he collected:

(green algae Caulerpa and Acetabularia)

(Sargassum fluitans)

And a red algae he has not yet identified.

JBug had a great time using the compound scope and looking at all of the neat little creatures that came in along with the seaweed: isopods, a bright green brine shrimp, diatoms, and a tiny little medusa worm. Now that was incredible looking–with long tentacles –the kids said it looked like some kind of  space alien!( ours was too tiny for pics, but here is what it looked like).

When Superboy went to the canal by the house to “release” our seaweeds he found a tiny upside-down jellyfish, which of course he brought to the house for us all to check out under the dissecting microscope:

This kind of jellyfish is pretty common here, but we’ve never seen such a tiny one before.They can get very large. We’ve seen them up to a foot or more across, but this one was only an inch or so.

Even JackJack had to get a look at this fascinating critter.  The compound scope is still difficult for him, but he loves to look at stuff under the dissecting scope!

When we had all had a good look, Superboy released it back into the canal.

A very satisfying day!

Now have a look at what some other fieldworkers are up to: Nature’s Sweetness did some great salinity experiments and A Baker’s Dozen is rocking the seaweeds!

Great work, Folks!

  1. Would you mind giving me some information on both your scopes? I’d love to know what kind they are and where you got them! Thanks!

    • Sure, Charlotte!
      The compound scope is from Home Science Tools, I believe this one I really like the National brand scopes for quality optics.
      Our dissecting scope was a donation from the university I went to grad school. It is much pricier than I can afford, so I am thankful for that donation! But Home Science Tools sells some similar ones. Just look under dissecting (or stereo) microscopes. These are really great for looking at stuff you can’t stick on a slide–larger items, living critters, your fingers, etc.We actually use our dissecting scope more frequently than our compound scope.
      Hope that helps!

  2. Wow, you guys found some GREAT algae!! It looks like we need a differnt scope too, hoping for a donation from the head mistresses paternal side :))) Love the cutie looking too, what a great pic! Looking forward to our seaweed week!

  3. Looks like things are going along *swimmingly*!
