Mesenchytraeus Eastwoodi
Ice worms (also written as ice-worms or iceworms) are enchytraeid annelids of the genus ''Mesenchytraeus''. The majority of the species in the genus are abundant in gravel beds or the banks of riverine habitats, but the best-known members of the genus are found in glacial ice. They include the only annelid worms known to spend their entire lives in glacial ice, and some of the few metazoans to complete their entire life cycle at conditions below . They were discovered in a wide range of environments, which include level snowfields, steep avalanche cones, crevasse walls, glacial rivers and pools, and hard glacier ice. These organisms are unique in that they can simply move between tightly packed ice crystals. They utilize setae, which are small bristles found on the outside of their bodies, to grip the ice and pull themselves along. The genus contains 77 species, including the North American glacier ice worm (''Mesenchytraeus solifugus'') and the Yosemite snow worm (''Mesenchytr ...

It was also common practice to add the sign at the end of the alphabet as if it were the 27th letter, pronounced as the Latin ''et'' or later in English as ''and''. As a result, the recitation of the alphabet would end in "X, Y, Z, ''and per se and''". This last phrase was routinely slurred to "ampersand" and the term had entered common English usage by 1837. It has been falsely claimed that André-Marie Ampère used the symbol in his widely read publications and that people began calling the new shape "Ampère's and". History The ampersand can be traced back to the 1st century A.D. and the old Roman c ...
