The Harderian gland is a gland found within the eye's orbit that occurs in tetrapods(reptiles, amphibians, birds and mammals) that possess a nictitating membrane.

The gland can be compound tubular orcompound tubuloalveolar, and the fluid it secretes (mucous, serous or lipid) varies between different groups of animals. In some animals, it acts as an accessory to thelacrimal gland, secreting fluid that eases movement of the nictitating membrane. Research has proposed that the gland has several other functions, including that of aphotoprotective organ, a location of immune response, a source of thermoregulatorylipids, a source of pheromones, a site ofosmoregulation, et al.In mammals, the gland excretes an oily substance used to preen the fur. The presence or absence of this gland is one of the cues used by palaeontologists to determine when fur evolved in the ancestors of mammals.

Red gland is present in fish...
It helps the fish to swim by releasing the air into air bladders in order to increase the buoyancy....
