Gorgonacea is an order of sessile colonial cnidarian found throughout the oceans of the world, especially in the tropics and subtropics. Gorgonians are also known as sea whips or sea fans and are similar to the sea pen, another soft coral. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in captive reef aquariums. The name "Gorgonacea" is no longer considered valid and Alcyonacea is now the accepted name for the order.

Xanthosoma is a genus of about 50 species of tropical and sub-tropical arums in the flowering plant family, Araceae, all native to tropical America. Several species are grown for their starchy corms, an important food staple of tropical regions, known variously as malanga, otoy, otoe, new cocoyam, tannia, tannier, yautía, macabo, taioba, dasheen, quequisque, ‘ape and (in Papua New Guinea) as Singapore taro (taro kongkong). Many other species (including especially X. roseum) are utilized as ornamental plants, and in popular horticultural literature are known as ‘ape or elephant ear (from the purported resemblance of the leaf to an elephant's ear), although the latter name is sometimes also applied to members with similar appearance and uses in the closely related genera of Caladium, Colocasia (i.e., taro), and Alocasia.

The leaves of most Xanthosoma species are 40-200 cm long, sagittate (arrowhead-shaped) or subdivided into 3 or as many as 18 segments. Unlike the leaves of Colocasia, those of Xanthosoma are usually not peltate- the upper v-notch extends in to the point of attachment of the leaf petiole to the blade.

Trousers are an item of clothing worn on the lower part of the body from the waist to the ankles, covering both legs separately (rather than with cloth stretching across both as in skirts and dresses). The word trousers is used in the UK and Ireland, but some other English-speaking countries such as Australia, Canada, South Africa, and the United States can also refer to such items of clothing as pants. Additional synonyms include slacks, strides, kegs or kex, breeches (sometimes britches pronounced /ˈbrɪtʃɨz/), or breeks. Shorts are similar to trousers, but with legs that come down only to around the area of the knee, higher or lower than the knee depending on the style of the garment.
In most of the Western world, trousers have been worn since ancient times and throughout the Medieval period, becoming the most common form of lower body clothing for males in the modern period, although shorts are also widely worn, and kilts and other garments may be worn in various regions and cultures. Shorts are often preferred in hot weather or for some sports, and also often by children. Since the late 20th century, trousers have become prevalent for females as well. Trousers are worn at the hips or waist, and may be held up by their own fastenings, a belt, or suspenders (braces). Leggings are form-fitting trousers of a clingy material, often knitted cotton and lycra.
