The Portulacaceae are a family of flowering plants, comprising 115 species in a single genus Portulaca. Formerly some 20 genera with about 500 species, were placed there, but it is now restricted to encompass only one genus, the other genera being placed elsewhere. The family has been recognised by most taxonomists, and is also known as the purslane family. It has a cosmopolitan distribution, with the highest diversity in semiarid regions of the Southern Hemisphere in Africa, Australia, and South America, but with a few species also extending north into Arctic regions. The family is very similar to the Caryophyllaceae, differing in the calyx, which has only two sepals.
The muriquis, also known as woolly spider monkeys, are the monkeys of the genus Brachyteles. They are closely related to both the spider monkeys and the woolly monkeys. The two species are the southern and northern muriquis. They are the two largest species of New World monkeys, and the northern species is one of the most endangered of all the world's monkeys.
The northern muriqui is one of two species of muriqui. They are also known as woolly spider monkey because they exhibit the woollen pelt of woolly monkeys and the long prehensile tail of spider monkeys. Muriquis are the largest extant New World monkeys. They can reach 4.3 feet or 1.3 metres long and weight up to 7 to 10 kilograms. The northern muriqui is a critically endangered species that is unusual among primates in that they display egalitarian tendencies in their social relationships. This species is endemic to the Atlantic Forest region of Brazilian states of Rio de Janeiro, Espírito Santo, Minas Gerais and Bahia. Their diets, travel patterns and reproductive cycles are seasonally determined. The size of each group can fluctuate as females will move between groups of monkeys.
The southern muriqui is a muriqui species endemic to Brazil.
Calymene Brongniart, 1822, is a genus of trilobites in the order Phacopida, suborder Calymenina, that are found throughout North America, North Africa, and Europe in primarily Silurian outcrops.

The cephalon is the widest part of the animal and the thorax usually has 13 segments.
