Task: Text Categorization
Input (English): One of these organisms, Tesnusocaris goldichi, possessed uniramous instead of biramous appendages. One structure that characterizes this phylum undergoes apolysis and ecdysis and is composed of proteins like resilin or sclerotin interwoven with fibrous alpha-chitin. That structure, often mineralized with calcium carbonate, is a cuticle. Animals in this phylum uptake waste from their hemolymph using Malpighian tubules and also possess open circulatory systems and jointed legs. For 10 points, name this phylum of segmented invertebrates protected by exoskeletons, which includes crustaceans, arachnids and insects.
Output (English): Science
