“Crohn's Disease can affect any part of the alimentary canal, from the mouth to the anus, but commonly affects the small and large intestines.”

“Breathing through the anus allows nymphs to propel themselves through the water with a sudden, turbo-charged burst of speed to escape predators.”

“The larvae, or nymphs, have feathery gills – located in the anus – that are especially vulnerable to toxins.”

“Although older texts emphasized parasitic infestation, this is a rare cause of pruritus ani except for pinworms in children.”

“As the levator ani passes downward both anteriorly and posteriorly, it forms an arch of muscular tissue, also called a sling.”

“These are usually fibrous when situated below, or vascular when situated above, the sphincter ani muscle.”

“Greater anis live in tropical coniferous forests, where trees don't shed leaves.”

“Because anis have altricial nestlings, the provisioning help of all breeding adults is essential.”

“On some occasions anis also use tamarin trees to roost or rest during the heat.”
