Banda Islands

The Banda Islands are one of Indonesia’s top destinations for divers. Both experts and beginners will enjoy themselves here as the diving ranges from the shallow lagoon between Banda Neira and Gunung Api, to the vertical walls of Hatta Island, the most easterly in the group.

Located in Maluku (Molluca) province, the Banda Islands are 200km from the nearest port town of Ambon, and are made up of 9 islands. Long known for their spices, these islands have attracted regional and international traders for more than 3.000 years. The first Europeans arrived in 1500. The biggest and most valuable commodities were nutmeg and cloves as, at that time, they were only found in the Banda Islands.

Diving in Banda

Set in the heart of Indonesia, the remoteness of the Banda Islands along with the low levels of human population, have meant less fishing and pollution pressures resulting in a vibrant, natural and healthy reef system.

Diving in the Banda Islands offers amazingly colourful walls, drop-offs, bommies and pinnacles!

The very clear and nutrient-rich upwelling waters bring in schools of hammerhead sharks, and pelagics such as sunfish (Mola-Mola), Dogtooth tunas, reef sharks, and sailfish. There are various ‘hammerhead hotspots’ where – at certain times of the year (Sep-Nov is best) – schools of more than 200 hammerheads have been witnessed. Whales also frequently pass through the strait.

Banda Diving Season

Diving is usually comfortable with average visibility of 15-30 meters, mild currents and calm waters. December/January (NW monsoon) June-August (SE monsoon) can have turbulent seas. The ‘best’ months are April and October 🙂

How to reach Banda

The Banda Islands are often included in some liveaboard schedules when crossing from Komodo, Raja Ampat, Alor or Flores.

And of course dive resorts offer attractive diving/accommodation packages. There are domestic flights from Jakarta and Bali to Ambon via Ujung Pandang (Makassar), and from there to the Banda Islands.

Indonesia is a Global Hotspot for Marine Biodiversity

Indonesia is a Global Hotspot for Marine Biodiversity

by Fahmi, AMD-B’s 2024 Divemaster Intern

Indonesia is a global marine biodiversity hotspot, hosting about 76% of the world’s coral species and approximately 37% of reef fish species, with over 2,200 reef-associated fish and 590 coral species thriving in its waters. So it’s safe to say that Indonesia is indeed a global hotspot for marine biodiversity, but the question now is why:

Strategic Location in the Coral Triangle

Indonesia is located in the Coral Triangle, a region known as the epicentre of marine biodiversity. The diverse coral species found in Indonesia are closely linked to the abundance of fish in the area. Corals are a key species in shallow water ecosystems, much like trees in a forest, supporting a wide range of marine life and making the region a hotspot for marine biodiversity.

Warm Tropical Waters

Indonesia’s climate is characterized by two seasons: wet and dry. While the wet season brings higher chances of rain at certain times of the year, the temperature remains relatively stable, creating an ideal environment for coral reefs to thrive. This consistency in water temperature, combined with strong sunlight exposure, supports coral health. Corals rely on sunlight for photosynthesis through their symbiotic relationship with zooxanthellae, the algae within their tissues.

Ocean Currents as Nutrient Highways

Strong ocean currents, such as those from the Indonesian Through-flow, funnel nutrient-rich water through the region. These nutrients support plankton growth, which forms the foundation of the marine food web. This abundance of food attracts fish, sharks, and larger marine animals, creating thriving ecosystems.

The Difference between Pygmy Seahorses

Pygmy Seahorses and Their Unique Characteristics

by Hafid, AMD-B’s 2025 Divemaster Intern

Pygmy seahorses are among the most fascinating and elusive creatures of the underwater world. With their tiny size and remarkable camouflage, they have intrigued marine enthusiasts and scientists alike. Found primarily in the coral reefs of the Indo-Pacific, these seahorses have adapted to blend seamlessly into their surroundings, making them difficult to spot even by the most experienced divers. Below is a detailed exploration of popular species of pygmy seahorses and their distinctive features.

Hippocampus bargibanti

Hippocampus bargibanti is one of the most well-known pygmy seahorse species, first discovered in the waters of Indonesia. It has a minuscule size, measuring only about 2.5cm in length. This species is frequently found hiding within red or orange sponges, which provide perfect camouflage. Its unique ability to blend into its habitat makes it incredibly difficult to spot, despite its relatively abundant population.

Hippocampus satomiae

This species was discovered in the waters around Halmahera Island in Indonesia. It is tiny, measuring around 2cm, and often resides in brightly coloured sponges. H. satomiae is known for its body texture and colouration, which closely resemble the sponges they inhabit, providing excellent protection from predators.

Hippocampus denise

Known as Denise’s Pygmy Seahorse, this species is even smaller than H. bargibanti, with a length of about 1.5cm. They are typically found in smaller sponges or coral reefs, often with vibrant colours like pink or orange. Found at depths between 10 and 50 meters, they have a slim, textured body, giving them a distinct appearance compared to other seahorses.

Hippocampus colemani

Found in the waters around Australia and Papua New Guinea, H. colemani is a slightly larger and fatter pygmy seahorse species. With lighter colours, they often hide in contrastively coloured sponges or corals. These seahorses prefer deeper waters, usually between 30 to 40 meters in depth.

Hippocampus pontohi

One of the smallest pygmy seahorses, H. pontohi has a body length of just 1cm. They are typically found hiding in brightly coloured sponges, particularly pink ones. Their exceptional camouflage makes them incredibly difficult to spot, even in areas frequented by divers.

Also, Hippocampus severnsi known as Severn’s seahorse is a small, rare species found in the Indo-Pacific region. Known for its distinctive appearance, it typically inhabits shallow coral reefs and seagrass beds. Like other seahorses, it feeds on small invertebrates. The H. severnsi was considered a separate species but is now recognised as a variation of the Pontohi.

The Importance of Pygmy Seahorses

Pygmy seahorses are fascinating not only for their size and camouflage but also for their role in coral reef health. All species rely on coral reefs and the shelter provided by sponges and other marine structures. Their small size and sensitivity to environmental changes make them important indicators of reef conditions.

As pygmy seahorses depend on healthy, undisturbed reefs, their presence or absence signals the reef’s overall health. With coral reefs threatened by acidification, habitat destruction, and climate change, protecting pygmy seahorse habitats is crucial for maintaining marine biodiversity. In short, pygmy seahorses are not only marvels of nature but also vital to the conservation of coral reefs and the broader marine ecosystem.
