The temperature of the waters the Common sole prefers normally ranges from 46.4-75.2 degrees Fahrenheit (8-24 degrees C).
However, the Dover sole does, at times, venture as deep as 660 ft (201 m) into the waters.

How do they reproduce?
Dover soles in different locations of the world have different mating or spawning seasons, but generally, Common soles mate all year round.
Despite being predominantly shallow-water fish, the Dover sole, in order to spawn, goes deep into the waters to about 1400 ft (426 m) below the surface of the water.
Females lay eggs or expel them in huge numbers ranging from 52,000-266,000 eggs, all of which are then fertilized outside the bodies of the female by the males. Once fertilized, these eggs turn into larvae that ultimately find deeper spots to settle into until they are old and capable enough to find shallow waters where they can establish nurseries.
Typically, the larvae find these deeper areas in order to exploit the favorable environmental conditions at those depths.
What is their conservation status?
Due to a lack of untrusted and sufficient data, the IUCN has been unable to classify it based on its population and conservation status. However, in most places in the world, the species seems to be performing well with respect to its total population.
