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.

Exact classification of some types of lemurs is a subject of debate, but it's generally accepted that there are five families of lemurs with about a dozen genera and just over 30 living species. Some species of lemurs are now extinct, including one ancient lemur said to be as large as a gorilla â over 400 pounds.
