Rate of convergenceIn numerical analysis, the order of convergence and the rate of convergence of a convergent sequence are quantities that represent how quickly the sequence approaches its limit. A sequence that converges to is said to have order of convergence and rate of convergence if The rate of convergence is also called the asymptotic error constant. Note that this terminology is not standardized and some authors will use rate where this article uses order (e.g., ).
Snake worshipSnake worship is devotion to serpent deities. The tradition is present in several ancient cultures, particularly in religion and mythology, where snakes were seen as the holders of knowledge, strength, and renewal. Ancient Mesopotamians and Semites believed that snakes were immortal because they could infinitely shed their skin and appear forever youthful, appearing in a fresh guise every time. The Sumerians worshipped a serpent god named Ningishzida.
Sea snakeSea snakes, or coral reef snakes, are elapid snakes that inhabit marine environments for most or all of their lives. They belong to two subfamilies, Hydrophiinae and Laticaudinae. Hydrophiinae also includes Australasian terrestrial snakes, whereas Laticaudinae only includes the sea kraits (Laticauda), of which three species are found exclusively in freshwater. If these three freshwater species are excluded, there are 69 species of sea snakes divided between seven genera.
Coral snakeCoral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 16 species of Old World coral snakes, in three genera (Calliophis, Hemibungarus, and Sinomicrurus), and over 65 recognized species of New World coral snakes, in two genera (Micruroides and Micrurus). Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World.
Snake venomSnake venom is a highly toxic saliva containing zootoxins that facilitates in the immobilization and digestion of prey. This also provides defense against threats. Snake venom is injected by unique fangs during a bite, whereas some species are also able to spit venom. The glands that secrete zootoxins are a modification of the parotid salivary glands found in other vertebrates and are usually located on each side of the head, below and behind the eye, and enclosed in a muscular sheath.
