A new species of Cyrtodesmus from Finca Merenberg, Huila, Colombia. For defense, this millipede can roll into a ball. It also secretes a sticky secretion that soil adheres to for camouflage. (Polydesmida, Cyrtodesmidae) #MillipedeMonday #Volvation

Cellaria pilosa from southern Australia, with ovicell. The tiny holes are assumed to be predation traces, and not related to the cuticular spines, which arise from the proximal end. Also a false-colour version. #bryozoa #predation #bryozoa ns

Lucernaria sainthilarei, lovely little stalked jellyfish. They live on muddy parts of the seafloor, clinging to boulders and small rocks. Usually these are places with gentle currents and depths greater than 15-20 meters.

This is an unidentified pyrosome, a colonial sister taxon to the salps, which are themselves related to the sea squirts we see on dock pilings. The name means “fire body” due to their long-lasting bioluminescence when touched. Some pyrosomes can get impressively large.

During our project work Smithsonian Panama taxonomy course, we found that hydrozoans show diverse fluorescence patterns that can vary across life stage and species🪼Happy to see our little study out Bridget Vincent stevehaddock.bsky Emily Lau Alexandra De León
