Remarks | Non-parasitic lamprey. Ammocoetes live in detritus-rich sands and clay sediments. They feed on diatoms and detritus. Ammocoetes larvae get up to 2-4 years old (Ref. 59043) and reach up to 13 mm TL. Metamorphosing individuals do not feed at all. The feeding habits of adults remain obscure but are assumed to not be herbivorous (RF). In the intestines of adults, only the remains of algae and higher plants are found. However, they may also feed on dead fish and are known to attach themselves to trout, presumably for transport. A 22% reduction in total length occurs from the pre-spawning to the spawning period. Adults die after spawning. |
