🎶 For herring, I'm caring, for tuna, I swoon-a, I'm faithful to whoever's here! When I'm not near the fish I love, I love the fish I'm near! 🎶

a little study of scales, texture, and light for a larger project I'm working on! also made this one into wrapping paper because I CAN'T be the only one who wants to wrap fish presents for people????

Phylogenetic Classification of Living and Fossil Ray-Finned Fishes (Actinopterygii)
Thomas J. Near, Christine E. Thacker
Abstract
Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the designation of taxonomic groups on the basis of morphological similarity.
Starting in the late 1960s morphological phylogenetics became the basis for the classification of Actinopterygii but failed to resolve many relationships, particularly among lineages within the hyperdiverse Percomorpha.
The introduction of molecular phylogenetics led to a dramatic reconfiguration of actinopterygian phylogeny. Refined phylogenetic resolution afforded by molecular studies revealed an uneven diversity among actinopterygian lineages, resulting in a proliferation of redundant group names in Linnean-ranked classifications.
Here we provide an unranked phylogenetic classification for actinopterygian fishes based on a summary phylogeny of 830 lineages of ray-finned fishes that includes all currently recognized actinopterygian taxonomic families and 287 fossil taxa.
We provide phylogenetic definitions for 90 clade names and review seven previously defined names. For each of the 97 clade names, we review the etymology of the clade name, clade species diversity and constituent lineages, clade diagnostic morphological apomorphies, review synonyms, and provide a discussion of the clade's nomenclatural and systematic history.
The new classification is free of redundant group names and includes only one new name among the 97 clade names we review and describe, yielding a comprehensive classification that is based explicitly on the phylogeny of ray-finned fishes that has emerged in the 21st century and rests on the foundation of the previous 200 years of research on the systematics of ray-finned fishes.

earth fact time. this is NOT A DRILL! two great white sharks have become best friends!! their names are simon and jekyll and they've travelled together for over 4,000 miles. this is a huge discovery, because great white sharks are usually solitary creatures!
an important note is that these sharks aren't swimming side by side, and are usually a couple kilometres off from each other - but their trackers kept pinging in the same part of the ocean at the same time. scientists think they might be brothers, or following a previously unknown migratory path.
