The range of scarlet kingsnakes extends considerably further north and northeast than the eastern coral snake. [11] [12] The scarlet kingsnake was once believed to have intergraded with the eastern milk snake, which produced a variation once named as a subspecies called the Coastal Plains milk snake (L. t. temporalis), but this is no longer ...
Scarlet snakes rarely bite when picked up by humans, although they can release a foul-smelling odor. [6] The Scarlet snake will use its version of batesian mimicry and mimic the coral snake as a defense mechanism in order to reduce predation, and show predators that it is a venomous species. [15]
Coral 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 27 species of Old World coral snakes, in three genera (Calliophis, Hemibungarus, and Sinomicrurus), and 83 recognized species of New World coral snakes, in two genera (Micruroides and Micrurus).
Some harmless milk snake (Lampropeltis triangulum) subspecies, the moderately toxic false coral snakes (genus Erythrolamprus), and the deadly coral snakes (genus Micrurus) all have a red background color with black and either white or yellow rings. Over 115 species or some 18% of snakes in the New World are within this mimicry system. [10]

For example, when predators avoid a mimic that imperfectly resembles a coral snake, the mimic is sufficiently protected. [ 26 ] [ 27 ] [ 28 ] Convergent evolution is an alternative explanation for why coral reef fish have come to resemble each other; [ 29 ] [ 30 ] the same applies to benthic marine invertebrates such as sponges and nudibranchs .
Like other scarlet snakes, the Florida scarlet snake is a secretive, burrowing species, preferring habitats of soft soils, often in open forested areas or developed agricultural land. They spend most of their time hidden, emerging to feed on small rodents and lizards , but they have a particular taste for reptile eggs , swallowing them whole or ...
Highly venomous eastern coral snakes just got a lot more intimidating, after a Florida biology student found one that doesn’t look like the photos in textbooks. Coral snakes are famously ...
