It's time for another Map of Life update. There are 4 new species this time, the Paraselachimorpha in the top left corner. There's more map of life action here: matildaslab.wordpress.com/map-of-life/ #scicomm #sciart #evolution #biology
A taxonomic map titled "Map of Chondrichthyes" by Matilda's Lab, illustrating the hierarchical classification of cartilaginous fishes using nested colored circles. The chart is divided into major sections for Holocephali (chimaeras) and Elasmobranchii (sharks, rays, and skates). Elasmobranchii branches into Selachimorpha (sharks like Carcharhiniformes, Lamniformes, and Squaliformes) and Batoidea (rays and skates like Rajiformes, Myliobatiformes, and Pristiformes). Each group features detailed circular illustrations of representative species, families, and orders, with a taxonomic rank legend at the bottom-left and the Matilda's Lab logo at the bottom-right.
