From The Featured Creature:
Swimmingly peacefully through the dark waters of the ocean the world over are marine planktonic polychaete worms in genus Tomopteris. These mesmerizing creatures are relatively transparent until they shine a deep bioluminescent blue. One species, Tomopteris nisseni, is one of the few creatures on the planet to produce yellow bioluminescence.
Others in this genus are capable of dispelling a flurry of bioluminescent sparks from their parapodia. This is used to distract predators, making them go after the discharged glow instead of the actual animal.
They only reach a few centimeters in length, not counting the full tail length which varies and their antennae, but no matter the size of this spectacular creature it’s impossible to take your eyes off its captivating undulating body as it rhythmically slinks through the darkness.

Art from Helen Gregory’s exhibit Unrequited Death which features work she has created during her time as the artist-in-residence at the Canadian Museum of Nature. It will run through September 3, but if you can’t see the work in person you can always download her app.
About the exhibit:
In her unique creations, Newfoundland artist Helen Gregory juxtaposes biological specimens with fanciful, even romantic, backgrounds reminiscent of the Victorian era.
Unrequited Death presents both the macabre and magical, revealing a fascination with dead things and evoking an age-old obsession with collection.
“Confocal image showing damaged collagen fibres in a ruptured tendon. The area of wavey fibres to the lower right shows the normal healthy appearance of tendon. The waviness allows the whole tendon to have a small amount of elasticity (2-10%) as the collagen fibres themselves do not stretch. The field of view is approximately 220 microns across”
These are what my tendons look like? Creepy/cool.
The spherical alga Volvox swims by means of flagella on thousands of surface somatic cells. This geometry and its large size make it a model organism for studying the fluid dynamics of multicellularity. Remarkably, when two nearby Volvox colonies swim close to a solid surface, they attract one another and can form stable bound states in which they “waltz” or “minuet” around each other.
Somehow microorganisms manage to be cute? I saw these so often in undergraduate lab, but never knew they could do this. Aw.
