Types of excretion

Different animals have different ways of eliminating different nitrogenous compounds. There are basically three types of excretion that can be explained properly with excretion homework help. They are as follows –

  • Ammonotelism – Ammonia is the main nitrogenous waste material in this type and animals which eliminate such wastes are called ammonotelic. These animals are found in aquatic animal groups like coelenterates, sponges, echinoderms, crustaceans, bony fish, salamander and tadpole larvae.
  • Uricotelism – Uric acid as a nitrogenous waste is the main elimination in this type and the animals showing uricotelism are known as uricotelic. Birds, insects, land reptiles, land snails and some land crustaceans fall in this category.
  • Ureotelism – Urea is the main nitrogenous waste in this type and animals showing ureotelism are known as ureotelic animals. This is common in land animals such as whales, rat, seals, frogs, toads, kangaroo, cartilaginous fishes, alligator, turtles and terrapins.
