Notothenioids are a suborder of fishes that make up the primary fish fauna of the Southern Ocean.
The Southern Ocean surrounds Antarctica and generally stays between -1.9 and +1 degree Celsius all year, and has been this cold for several million years.
Molecular thermosensors that function below ~8 degrees C have not been discovered.
I am investigating how TRP channels have evolved to sense ecologically relevant temperatures for these fish.
