Currently, only one species, Trichoplax adhaerens, is acknowledged to belong to the Placozoa. The Italian Francesco Saverio Monticelli described another species in 1893, which he found in the waters around Naples, naming it Treptoplax reptans.
A standard mallet has a head length of 9 to 9.5, and this is recommended for beginners. Expert players may use longer head lengths up to 12, as this is thought to make aiming more accurate and makes it harder to accidentally twist the mallet during the stroke.
A drum carder is used to card fibers such as wool fleeces, alpaca locks, angora and other fibers. Most carders have two drums. The smaller drum is designed to draw the fibers in, transferring it to the larger drum thus creating a batt for spinning and felting.erfect if you have lots of fleeces to card. Almost 12 inches in width, the Louet XL Drum Carder is huge. Combine that with the large diameter drum that makes a batt approx. 30 by 12 and you will go thru your fleeces better than ever before.
