  • The Sonoran and Milk snakes are similar because they evolved to mimick venomous prey and avoid predators. Sonoran Shovel and Mountain King Snakes as well as the Milk Snake have similar ringed patterns as the venomous, Sonoran Coral Snake; because, predators confuse other species for the aposematic coral snake as an occurrence of batesian mimicry.

For example, 5.2 units of the Garter Snake are consumed by weasels, hawks, and badgers. (The Garter Snake is consumed more than the hare's 4 units a day).  Whereas, only 0.07 units of coral snake are consumed by predators daily. Mimicry species like the Milk Snake or Shovel-Nosed Snake, are consumed by 0.05 units per day and 0.06 units per day.]]> 2018-05-09 17:49:40 UTC https://padlet.com/csalinas874/8odglx24s7iq/wish/259393621 Evidence 2: Geographical Trends csalinas874 https://padlet.com/csalinas874/8odglx24s7iq/wish/259393661 The Sonoran Coral Snake and their mimics occupy the same areas of southern Arizona as the Garter and Western snakes. Over time,  the mimics have evolved independently and developed  traits analogous to the Sonoran Coral Snake.  The Milk Snake, Mountain King Snake, and the Shovel-nosed Snake have have developed these analogous traits to mimick aposematic scales and further avoid predators. Analogous traits are a form of convergent evolution that develop when two organisms face similar environmental pressures. In the case of the mimics, this would be predators like the weasel and hawk.

It's a protective device against predators. This makes them appear toxic and harmful, when they are really not. ]]> 2018-05-10 13:47:43 UTC https://padlet.com/csalinas874/8odglx24s7iq/wish/259615359 Sonoran Mountain King snake jgalvez107 https://padlet.com/csalinas874/8odglx24s7iq/wish/259620964 2018-05-10 13:58:56 UTC https://padlet.com/csalinas874/8odglx24s7iq/wish/259620964 Milk snake jgalvez107 https://padlet.com/csalinas874/8odglx24s7iq/wish/259622022 2018-05-10 14:01:10 UTC https://padlet.com/csalinas874/8odglx24s7iq/wish/259622022 Sonoran Shovel-Nosed snake jgalvez107 https://padlet.com/csalinas874/8odglx24s7iq/wish/259622429 2018-05-10 14:02:02 UTC https://padlet.com/csalinas874/8odglx24s7iq/wish/259622429 Sonoran Coral snake jgalvez107 https://padlet.com/csalinas874/8odglx24s7iq/wish/259623053 2018-05-10 14:03:23 UTC https://padlet.com/csalinas874/8odglx24s7iq/wish/259623053 Terrestrial Garter snake jgalvez107 https://padlet.com/csalinas874/8odglx24s7iq/wish/259625482 Because of its lack of adaption it gets eaten a lot more often.]]> 2018-05-10 14:08:20 UTC https://padlet.com/csalinas874/8odglx24s7iq/wish/259625482
