Ankhegs are a type of monster in ADOM. They are notable due to their ability to breathe a stream of acid and a corresponding immunity to all acid-based attacks. They are also able to dig through walls.

Eating an ankheg can grant the PC acid resistance ("Your stomach tingles"), but also makes them 'throw up' (which seems to decrease satiation a lot more than 'vomiting'; despite the terms being synonyms).
This large acid spitter looks similar to a praying mantis, but whether it is an insect variant or not is unknown. Some suspect it to be a highly specialized reptile due to its acidic spittle, but others hold the chitinous exterior and multi-faceted eyes as evidence of its insect nature.
