The carriagebracket moves along the underside of the angle plate in adovetail and keeps the angle plate from moving in or out onthe bed bracket.
The Bryozoa, also known as Polyzoa, Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals.Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a crown of tentacles lined with cilia.nother group of animals discovered subsequently, whose filtering mechanism looked similar, was also included in Bryozoa until 1869, when the two groups were noted to be very different internally. The more recently discovered group was given the name Entoprocta, while the original Bryozoa were called Ectoprocta.
Because B. tridactylus is both heterotrophic and multicellular, it is listed in the kingdom of Animalia. Due to the fact that the pale-throated three-toed sloth has a backbone, it belongs to the phylum Chordata.Because the B. tridactylus is covered in hair and has mammary glands it lies within the class Mammalia.The order Xenarthra is a group of insecivors and include the armadillo, anteater, and the sloth (our B. tridactylus). The family Bradipodidae consists only of the three-toed sloths.The genus Bradypus also only consists of three-toed sloths.he order Xenarthra is a group of insecivors and include the armadillo, anteater, and the sloth (our B. tridactylus).
