List Child Taxa in Catalogue of Life

List the immediate child taxa of a given taxon in the Catalogue of Life taxonomic tree. For example: pass the ID for a family to get its genera; pass a genus ID to list its species; pass an order ID to enumerate its families. Returns paginated results with up to 100 children per call, each including taxon ID, scientific name, rank, status, and higher classification. Use offset for pagination over large groups (e.g. Coleoptera has 400K+ species). Obtain the taxon_id from col.species.search or col.species.suggest. CC BY 4.0 — ~10 million taxa across all kingdoms including Animalia, Plantae, Fungi, Bacteria, Archaea, Protista, Chromista, and Viruses.
