|Current Population Trend:||Unknown|
|Habitat and Ecology:||Habitat:|
Found in the lowland, piedmont and montane zone in clear, well oxygenated brooks. Ammocoetes live in detritus-rich sands or clay sediments.
Non-predatory, freshwater resident. Timing of spawning season depends on latitude when temperature exceeds 9°C, starting in February in Italy and mid-June in Finland. Spawning individuals cease their normal daylight avoidance reaction and reproduce on sunny days. Males dig a shallow nest in habitats with moderate current. Spawners form large aggregations. Dies after spawning. Single individuals may survive until September. Ammocoetes stage usually lasts 21/2-3 1/2 years. Feeds on detritus and micro-organisms, starts metamorphosis in June-July (fully transformed individuals usually found in September), overwinters and spawns following spring. There are indications that L. planeri might be an heterogeneous (polyphyletic) assemblage of several lineages evolved independently from different populations of L. fluviatilis (see family introduction).
|Major Threat(s):||No major threats known.|
|Conservation Actions:||No information available.|
|Errata reason:||When the 2010 assessment of this species was published in 2011, a 2013 citation reference was accidentally attached to the account and hence the previous version of the assessment showed it as being published in 2013 when it should have been 2011. The error is corrected here and is therefore given a 2016 citation date; the 2011 reference that should have been used in the citation is under the References.|
