Next set of observations from the same sample of pond water from my backyard (also includes some moss from the tree in the front yard). IMPORTANT: this time, I did not ingest any pond water at all. Yay for small victories!
I’ve enjoyed this enough I really want to consider getting a “real” microscope.
I don’t really have terribly good identifications for all of this.
I think this is an ostracod. It was about 2/3 mm long.
I’m not sure what this is. Maybe another ostracod? It was about 1.5mm long.
I have no idea what’s going on here. On the lower right, I think is an ostracod. The rest of the object seems to be the carcass of an insect, perhaps? About 2mm long.
Took some moss from the tree in front of the house; mixed it with water from the pond behind the house. First cut at using the digital microscope, this is a copepod female with eggs, I believe. Next time, I’ll try to look for other creatures.
First lesson learned: NEVER EVER TRY TO USE A STRAW AS A PIPETTE, GAURAV, YOU IDIOT. Especially when dealing with pond water.
It seems that Youtube degraded the video quality quite a bit, unfortunately; the original video looks much sharper.
Took out the Laowa 24mm probe lens to look underwater. It’s been rainy for many days now, so the marshy area was filled with water (it’s often dried out).
I mostly looked in a little bit of the marsh that was cordoned off from the rest. That area turned out to have by far the most ostracods and copepods. Taking photos of them was pretty difficult, but out of several hundred photos, I got a few decent shots.
It was surprising there was so much activity at this time of year (New Year’s Day!). Even the caddisfly larvae were everywhere. And it was even more surprising that so many of them were with eggs; what would they have done if it were freezing at this time, or if there were no rain?
All identities are my best guess, I’m still learning as I go!
Copepod female, I think:
And another:
And another! You begin to get the idea. Fecundity rampant.
A better view of the male in the previous photo. I couldn’t tell if they were actually interacting, but they stayed together for a several seconds.
Copepod male, I think:
In focus, while swimming. Believe me, this was not an easy photo to take:
This is another copepod. Those sphere that look like eggs are actually fatty globules stored inside the body. The orange color comes from carotenoids.
I think this is another copecod, but again, I’m still trying to pick this up:
A caddisfly larvae in its casing. You can see the legs, but the main body is out of focus:
This photo was taken in the pool on the vernal pool trail. I have no idea what I’m looking at. It was a mass attached to a leaf, on the surface.
Now for some photos that do not involve exoskeletons:
Rain droplets are sometimes better when out of focus. The shiny bright light gets lost in the photo if the droplet is in focus (because the dynamic range of the camera is less than that of the eye), but can be seen better by spreading it out.
In this case, they didn’t need that help:
I took a series of photos of this wonderful set of droplets on a leaf in the marsh. No way I could have reached them without using the Laowa lens. The light was striking it just right.
Is this a slime mold? EDIT: no, looks like one, but more likely to be the fungus Ceriporia spissa.
An experimental photo. I took a long exposure of the stream, and panned the camera along the length of the stream. Anything not changing comes out as a pure streak, while the bubbles and other features that changed over the length of the exposure stand out.
Long weekend in Southeastern Maine! First time exploring the area.
Rachel Carson National Refuge
Goose Rocks Beach, Cape Porpoise
Wells Jetty
This was tough…wasn’t easy to take photographs I was happy with. Ended up with a lot of longer exposure photos of the waves, the birds, and the waves and birds together. Not sure how good they will look to other people!
Trying to capture the movement of the birds as they swayed up and down the beach with the waves:
A flock of birds in motion:
Bonus Tiger Beetle
This lovely Cicindela sexguttata, Six-spotted Tiger Beetle, was waiting to welcome us home when we got back. Definitely has sustained quite a bit of damage, but lovely nonetheless.
