Marine life is exceptionally diverse, with over 350 species of reef fish and 100 species of coral documented. The waters host hawksbill turtles, green sea turtles, and various reef sharks. Notable fish species include clownfish, angelfish, and parrotfish. Bird life is significant, with species like the white-bellied sea eagle and common sandpiper frequently spotted. The mangrove ecosystems support populations of mud crabs, monitor lizards, and various mollusks. Several islands also serve as important nesting sites for sea turtles.
The islands support a diverse tropical ecosystem dominated by coastal vegetation. Coconut palms (Cocos nucifera) are abundant, alongside mangrove forests featuring species like Avicennia marina and Rhizophora mucronata that play crucial roles in coastal protection. Beach morning glory (Ipomoea pes-caprae) and sea lettuce (Scaevola taccada) thrive along the shorelines. Several islands also harbor small patches of tropical lowland forest with species such as Sea Poison Tree (Barringtonia asiatica) and Indian Almond (Terminalia catappa).
The archipelago consists of 110 coral-fringed islands formed through volcanic and tectonic activity in the Java Sea. These islands represent the northward extension of Jakarta's coastal plain, with most featuring low-lying coral reef platforms that rarely exceed 3 meters above sea level. The island formation process continues today through coral growth and sedimentation. The surrounding waters average 20-30 meters in depth, creating ideal conditions for coral reef development. White sandy beaches, derived from eroded coral, characterize most islands' shorelines.
The Thousand Islands archipelago has a rich maritime history dating back to the 17th century when it served as a strategic outpost for the Dutch East India Company. The islands were vital stopping points along ancient trading routes between China, India, and the Middle East. Dutch colonists established coconut plantations and built several fortifications, including the historic Martello Tower on Pari Island. In the 19th century, the islands gained importance as a quarantine station for Hajj pilgrims. Today, while some islands have developed into tourist destinations, others maintain traditional fishing communities that preserve centuries-old maritime customs.
The archipelago's most distinctive features include its extensive coral reef systems, particularly around Pramuka and Kotok islands, which offer world-class snorkeling and diving opportunities. Historical structures like the 19th-century Onrust Island lighthouse and Dutch colonial ruins provide cultural interest. The islands are also known for their floating fishing platforms (kelong), traditional stilt houses, and pearl farms. Several marine research stations and turtle conservation centers offer educational experiences, while luxury resorts on islands like Pulau Macan showcase eco-friendly tourism development.
Kepulauan Seribu experiences a tropical monsoon climate with two distinct seasons. The dry season runs from April to October, offering ideal conditions for water activities with calm seas and minimal rainfall. The wet season spans November to March, bringing occasional heavy rains and rougher seas. Year-round temperatures remain consistently warm, averaging 27-30°C (81-86°F), while humidity levels typically range from 75-85%. Water temperatures stay pleasant at 26-29°C (79-84°F) throughout the year, making the archipelago suitable for swimming and snorkeling in any season.
