Step-by-step solution
Ammonotelism is seen in aquatic animals like fish, where ammonia is excreted. Ureotelism is typical in mammals, where urea is the main excretory product. Uricotelism occurs in birds and reptiles, where uric acid is excreted. Guanotelism is found in some arachnids, such as spiders and scorpions, where guanine is excreted.
