In some teleosts, the presence of thyroid follicles in various abnormal locations such as the main kidney, brain, esophagus and pleura has been reported. It is thought that it also plays a role in reproduction and spawning. They are separated by connective tissue and surrounded by fibrous capsules. Hormones thus play a role in regulating circulation, gas metabolism, buoyancy, corticotropin release, and smooth muscle contraction.
