Although salamanders may seem defenseless to the human eye, they have several processes and defense mechanisms that ensure them a long life span of up to 20 years.
Day-active predator: Weasel
Active-night predators: Raccoon and Cobra Snake
Due to having predators that are active at day, this explains the reason spotted salamanders sleep during the day where predators can't reach them. Unbeknownst to most people, spotted salamanders also have predators that are active at night.
Now that night has come, the night-active predators stir, and proceed to look for a meal. "Uh-Oh!", it seems that the cobra snake has spotted the also stirring salamander before the raccoon.
As the raccoon scurries off the find another meal, the cobra snake strikes, grabbing onto the salamander with its powerful teeth.
When all hope seems to be lost for this spotted salamander, the cobra snake suddenly drops the salamander and scurries off; looking for another less venomous meal elsewhere. This spotted salamander has just used her defense mechanism in which her tail releases a sticky toxin as a predator bites into it By having her life saved, the salamander loses her tail as sacrifice. After a long night, the salamander goes in search of her own food in a nearby swamp.
