Topic: Waste Excretion During Air Breathing

My Edit: The African Lungfish can partake in aestivation on land within a dry mucus cocoon. As most tropical fish are ammoniotelic, being on land can induce ammonia toxicity – with both organismal level and cellular level consequences – due to a lack of water to flush the excreted ammonia across the gills and other cutaneous surfaces. Studies have shown the African Lungfish has evolved the mechanism of increased rates of conversion of ammonia to urea, as well as reducing endogenous ammonia production, in defense to this toxicity.

Where on the Article will I add my edit: under the biology section right after the last sentence mentioning aestivation.
