"Plemeniti rakovi" i "Lasica" motivi su ove godine lihtenštajnskih marki Europa (01. ožujak 2021.). Države članice udruženja europskih javnih poštanskih operatora (PostEurop) svake godine izdaju marke na zajedničku temu; 2021. to je "Ugrožena nacionalna divljina".
Kao najmanji grabežljivac na svijetu, lasica naseljava velike dijelove Europe i živi svugdje gdje postoje poljski miševi i skloništa. Od svog bliskog srodnika, hermelina razlikuje se po maloj tjelesnoj masi i kratkom repu, kojem nedostaje crni vrh. Vrste kune ugrožavaju širenje urbanih područja, promet i gubitak zemlje jer se danas intenzivno koristi u poljoprivredne svrhe.
Karakteristični za plemenite rakove su pandže crvene boje s donje strane i na zglobovima. Kao lokalni stanovnik, preferira nizinske potoke i mirne vode i uglavnom je noćni. Zagađenje vode, nakupljanje blata, ali posebno monotona izgradnja vodotoka i nepravilan ribolov glavni su čimbenici prijetnje. Međutim, najveća prijetnja svim domaćim vrstama rakova je kuga rakova.
The "Noble Crayfish" and the "Weasel" are the motifs of Liechtenstein's Europa stamps this year (01. March 2021.). The member states of the association of European public postal operators (PostEurop) issue stamps on a common theme each year; in 2021 it is "Endangered National Wildlife".
As the world's smallest predator, the weasel populates large parts of Europe and lives wherever there are field mice and shelters. It differs from its close relative, the ermine, by its small body mass and short tail, which lacks the black tip. The marten species is threatened by urban sprawl, traffic and the loss of land as it is now extensively used for agricultural purposes.
Characteristic of the noble crayfish are its claws, which are reddish in colour on the underside and at the joints. As a local resident, it prefers lowland streams and still waters and is predominantly nocturnal. Water pollution, accumulation of mud, but especially monotonous watercourse construction and improper fishing are major threat factors. However, the greatest threat to all native crayfish species is the crayfish plague.
