Classification
Nouns denoting body parts.
Examples
- Tuataras, many species of snakes, lizards, and frogs possess a parietal eye also called a third eye that allows light detection outside the other visual senses.
- During activity phases of daily locomotor rhythmicity the dorsal skin in third eye bearing areas responded differentially in 52 reptile species investigated from varied natural light exposures and climatic regimes.
- Their photosensitivity varies seasonally to third eye changes dependent upon sun periodic photic detection allowing enhanced timing endogenously triggered solar movements environmentally synchronous reptiles which develop similar regulation.
