In nature, vivid coloration on an animal generally serves as a warning to others that it is not afraid of delivering a dose of venom, or that it is poisonous if eaten; this "false warning" coloration is a form of mimicry, a survival adaptation in which a non-venomous species (i.e., the ring-necked snake) has evolved brighter coloration, similar ...
The northern ringneck snake has a body color from bluish grey to black, with a complete narrow yellow or orange ring around its neck and an underside matching the ring and generally lacking any dark spotting or patterning. The complete ring and lack of large dark spots on the belly differentiate it from other subspecies of D. punctatus. [5]
The belly also has black flecks along it. This snake has a blunt head, a tiny mouth, and small eyes. Anteriorly the dorsal scales are usually in 17 rows (other eastern subspecies have 15 rows). [4] A mature prairie ringneck grows to about 25–36 cm (9.8–14.2 in) in total length (including tail), record 42 cm (16 + 1 ⁄ 2 in). [5]
The black mamba (Dendroaspis polylepis) is a large and highly venomous snake species native to much of Sub-Saharan Africa. It is the second longest venomous snake species in the world and is the fastest moving land snake, capable of moving at 4.32 to 5.4 metres per second (16–20 km/h, 10–12 mph).
Like D. p. punctatus, the Mississippi ringneck snake characteristically attains a maximum length of 44.5 centimetres (17.5 in). The head is black and the body dark gray, separated by a golden ring at the neck. The ventral side displays a yellow belly, transitioning to dark orange under tail. [2]
The longest venomous snake is the king cobra (Ophiophagus hannah), with lengths (recorded in captivity) of up to 5.7 m (19 ft) and a weight of up to 12.7 kg (28 lb). [53] It is also the largest elapid. The second-longest venomous snake in the world is possibly the African black mamba (Dendroaspis polylepis), which
