Boa

Boa refers to several subjects, primarily a group of non-venomous snakes in the family Boidae, and also to a fashion accessory known as a feather boa. In snakes, boids are native to the Americas, from northern Mexico through Central America to South America, occupying habitats that range from forests and savannas to deserts and coastal areas. Boas are constrictors, subduing prey by coiling around it and applying pressure. They feed mainly on small to medium-sized mammals and birds, with occasional reptiles. Reproduction varies by species; many boas are ovoviviparous or viviparous, giving birth to live young after eggs develop inside the female. The common boa constrictor (Boa constrictor) is among the best-known species and is frequently kept in captivity. Boas generally have stout bodies, strong musculature, and thick heads, with many species being arboreal or semi-arboreal.

A feather boa is a long scarf made from feathers, worn as a fashion accessory or stage costume. It is typically lightweight and decorative, placed around the neck or shoulders. Feathers used include ostrich and marabou, among others, and synthetic versions are also common. Feather boas have appeared in theater, dance, and vintage fashion since the late 19th and early 20th centuries and remain a recognizable element of glamour in some contexts.
