To give bike frames their structural strength manufacturers employ a variety of unidirectional carbon fiber prepreg sheets. Each sheet is designated by the fiber orientation as being either a 0Â°, a plus 45Â°, a minus 45Â°, and/or a plus or minus 30Â°.
Sawfish are shark-like rays characterized by long, tooth-studded snouts. Individuals range in size from 2 to 20 feet and can weigh more than 1,000 pounds. Like most sharks and rays, sawfish are exceptionally vulnerable to overexploitation due to their slow growth, late maturity, and small number of young. All seven species worldwide are classified by the International Union for Conservation of Nature (IUCN) as Critically Endangered.
The Sailfin needs wood soft enough to regularly rasp at. Be sure to keep an eye on the wood as the pleco grows in case it needs to be replaced, since the pleco will be eating it. The Sailfin Pleco is a beautiful fish with the added benefit of providing maintenance and stability for the tank. Itâs hardy enough to live with aggressive species like cichlids, and low maintenance enough for beginners who want to try their hand at something a little more exotic.
