Atlantean Physiology refers to the biological make-up of citizens of Atlantis. Although a splinter species of baseline humanity, Atlanteans have evolved over the centuries and have adapted physical characteristics that make them more suited for life beneath the sea. A common misperception is that Atlanteans are amphibious. While this is partially true to some extent, modern-day Atlanteans can only exist outside of water for a limited duration before they begin to asphyxiate. Because Atlanteans have to adapt to living at varying pressure levels, their bodies are physically much heartier than the average human being, granting them:
In addition, Atlanteans have developed low-level telepathy which they use to broadcast and receive thoughts between one another. This is an Atlantean's primary means of communication. Some Atlanteans, such as Aquaman, have higher degrees of telepathy and can use it to communicate with other forms of sea life. This, however, is a rare instance and not a trait common to most Atlanteans.
Atlanteans are also natural swimmers.
