The San Juan Islands Group consists of 172 named islands of the more than 700 islands, islets and reefs identified at low tide and more than 400 at high tide. Additionally, the map shows the roads that connect the various communities and reach various points of interest on each of the four major islands.

Lemurs are generally the most social of the strepsirrhine primates and communicate more with scents and vocalizations than with visual signals. Many lemur adaptations are in response to Madagascar's highly seasonal environment.Lemurs have relatively low basal metabolic rates and may exhibit seasonal breeding, dormancy (such as hibernation or torpor), or female social dominance. Most eat a wide variety of fruits and leaves, while some are specialists.any lemur adaptations are in response to Madagascar's highly seasonal environment.
