Explanation:

The Harderian gland is a gland found in the eye's orbit that occurs in tetrapods (reptiles, amphibians, birds, and mammals) that possess a nictitating membrane. The proposed functions of the gland are remarkably diverse and include the gland being - a source of saliva; a site of immune response; a photoprotective organ; part of a retinal-pineal axis; a source of pheromones; a source of thermoregulatory lipids; a site of osmoregulation, and a source of growth factors.  The Harderian gland is either absent or vestigial in primates.
