The '''[[20 ice mark note]]''' is the first denomination of [[ice mark|ice marks]] to be issued by the [[Central Bank of Westarctica]]. As such, it is the first legal tender paper currency ever created by [[Westarctica]]. The initial release of the banknotes occurred on 27 February 2019.
The '''[[crabeater seal]]''' is a true seal with a circumpolar distribution around the coast of [[Antarctica]]. They are found primarily on the free-floating [[pack ice]] that extends seasonally out from the Antarctic coast, which they use as a platform for resting, mating, social aggregation and accessing their prey. They are by far the most abundant seal species in the world. While population estimates are uncertain, there are at least 7 million and possibly as many as 75 million individuals. This success of this species is due to its specialized predation on the abundant [[Antarctic krill]] of the [[Southern Ocean]], for which it has uniquely adapted, sieve-like tooth structure.


The 20 ice mark note is 70 mm x 140 mm in size (2.75 in x 5.5 in). It is printed on 75% cotton rag, 25% linen paper, the same fiber content as that of American banknotes. It contains red and blue fibers, has a weight of 85 GSM (grams per square meter) making it only slightly more dense/ heavy that typical office copy paper, and has no optical brighteners. Although the paper itself is waterproof and acid-free, the toner/ ink used for the production of the notes on this paper may be dissolved or damaged using certain aprotic solvents. Devoid of the toner/ ink, however, the paper has neither commercial nor symbolic/ economic value.
Despite its name, crabeater seals do not eat crabs. As well as being an important [[krill]] predator, the crabeater seal is an important component of the diet of [[leopard seal|leopard seals]], which consume about 80% of all crabeater pups.

The crabeater seal is a true seal with a circumpolar distribution around the coast of Antarctica. They are found primarily on the free-floating pack ice that extends seasonally out from the Antarctic coast, which they use as a platform for resting, mating, social aggregation and accessing their prey. They are by far the most abundant seal species in the world. While population estimates are uncertain, there are at least 7 million and possibly as many as 75 million individuals. This success of this species is due to its specialized predation on the abundant Antarctic krill of the Southern Ocean, for which it has uniquely adapted, sieve-like tooth structure.
