The bark scorpion and the grasshopper mouse have been coevolving with each other so closely that it has affected their physiology. The scorpion uses its stinger to inject toxins into the nervous and muscle tissues which causes disruption in the animal's sensory system. However, as the scorpions stinger evolves to become more toxic, the mice evolve in order to cope with the toxins. Therefore, the grasshopper mice have sensory neurons that have evolved which reject the toxin… WebJul 21, 2016 · A novel mechanism of resistance has been demonstrated in species of grasshopper mice ( Onychomys sp.) that regularly attack and eat bark scorpions ( Centruroides sp.) and sustain their stings ( Rowe and Rowe 2006, 2008 ).
Scorpion venom is a painkiller for the grasshopper mouse
WebBecause toxins act as stimuli that select for variants of genes encoding ion channels in grasshopper mice, we use cloning, site-directed mutagenesis and an expression system to assess the functional consequences of structurally modified channels.

WebOct 24, 2013 · Ashlee Rowe, lead author of the paper, previously discovered that grasshopper mice, which are native to the southwestern United States, are generally resistant to the bark scorpion toxin, which can kill other animals. It is still unknown why the toxin is not lethal to the mice. A grasshopper mouse attacks a bark scorpion. WebMar 1, 2006 · Grasshopper mice may have developed resistance to vertebrate-specific neurotoxins as an evolutionary response to selection by Centruroides. In turn, the extreme potency of venom in certain groups of scorpions, including Centruroides , may be the result of selection by tenacious and resistant mammalian predators such as Onychomys .
