pond scum ART – Ever seen algae up close?
TOPIA meets Instagram hit Couch Microscopy
Couch Microscopy unlocks a huge unseen world by turning the beautiful worlds of teeny hardcore things like algae into art – to help us better understand life on Earth. Plankton has never looked so good
Five years ago, Julia Van Etten was looking for a hobby to fill a year break in her studies to recover from late-stage Lyme disease. She bought a relatively inexpensive microscope, and started to collect water samples and take photos of what most people would consider scum. She then posted the breathtaking images on Instagram – on an account she called Couch Microscopy – to help more people appreciate biodiversity.
And that she did. Today over 32,000 followers are inspired by her images of algae, plankton, insect larvae, and microorganisms that the PhD student of ecology and evolution at Rutgers University collects from New Jersey bodies of water.
This just might be the coolest way of putting our pointillist landscape of tiny living beings into perspective.
We asked Julia to tell us about her 7 favourite images and then asked her a few Quick Q
“I love how these Cyanobacteria cells look like an abstract painting. Thank you Cyanos for giving us oxygen!”
“I picked this piece of seaweed up on the beach at the Jersey Shore and sliced it up with a scalpel to get a flat piece onto my slide. It’s very thick and gooey.”
Tiny snail shells
“I don’t know what snail these are from but they were stuck to a piece of seagrass and just looked like tiny white dots, almost invisible to the naked eye. I love snails and thought they photographed so beautifully when magnified.”
“This was the first intact marine centric diatom (photosynthesising algae) I ever found. It was from a water sample I collected along a brackish water canal while getting lunch on a family vacation to North Carolina.”
“I love photographing fish scales. They look kind of like human fingerprints. Lionfish are invasive and really damaging to ecosystems in the tropical waters of the western Atlantic.”
“Hydrodictyon is cool to find in freshwater streams and ponds. It is a filamentous green alga that forms hollow tube structures of hexagonal configurations of cells. These “water nets” can become so dense and populous that they block waterways! I collected this sample from a stream on the side of the road in my town.”
Colony of peritrich ciliates
“These ciliates form stalks from individual cells that allow a whole colony of cells to move together and react (expand and contract) in the presence of stimuli. Colonial protists are modern day examples of the behaviour that preceded the evolution of multicellularity in many protist lineages. By watching them move you are witnessing something analogous to an ancient process!”

What’s so good about this?
Algae is a big mystery of evolution. In order to understand these ancient wonders, they must be viewed with a microscope. It’s important to add context to lose barriers between scientists and non-scientists with citizen science projects and hobby microscopy.
