This is not an error; the ‘fishes’ filter is for ray-finned fishes, i.e., the class Actinopterygii, whereas sharks + rays are a class of their own, Elasmobranchii.

Those preset filters are not designed to be exhaustive, they’re meant to represent ‘iconic’ taxa, i.e. the ‘most famous’ coarse groupings. There are, however, a number of requests for other taxa to be included in these presets, e.g., [this](https://forum.inaturalist.org/t/make-crustaceans-and-myriapods-iconic-taxa/996) and [this](https://forum.inaturalist.org/t/create-iconic-taxa-for-bacteria-archaea-and-viruses/1464).
