 pretty_name: Rare Species Dataset
+description: >-
+  This dataset was generated alongside TreeOfLife-10M as a benchmark for BioCLIP; 
+  data (images and text) were pulled from Encyclopedia of Life (EOL) to generate a dataset
+  consisting of rare species for zero-shot-classification and more refined image classification tasks.
+  Here, we use "rare species" to mean species listed on The International Union for Conservation of Nature (IUCN) Red List 
+  as Near Threatened, Vulnerable, Endangered, Critically Endangered, and Extinct in the Wild.
