Discovery in Saleh Bay
On September 6, 2024, local fishers in the enclosed cove of Saleh Bay on Sumbawa island are scheduled to alert scientists after spotting a small whale shark caught in a night-time bagan net. Video captured at 04:30 showed a charcoal-coloured individual about 5 ft (1.5 m) long—approximately one-tenth the size of an adult. Marine wildlife expert Mochamad Iqbal Herwata Putra of the Jakarta-based nonprofit Konservasi Indonesia identified the animal as a four-month-old neonate, marking the first such discovery in Indonesia and one of only a few dozen documented worldwide.
Habitat Significance
Herwata Putra notes that Sale Bay’s abundant krill, sustained by surrounding mangroves, creates an ideal feeding ground for juvenile whale sharks. He suggests the sheltered cove may serve as a birthing or nursery area, offering protection from predators such as blue sharks. Research scientist Ben D'Antonio of the Shark Research Foundation agrees that locating a nursery is a “fundamental discovery” that could aid conservation of the endangered species, whose global population has declined by more than half since the 1980s.
Research and Conservation Efforts
The finding adds to the scant record of 33 neonate whale sharks observed across tropical oceans. Recent work by Freya Womersley (Marine Biological Association) links such sightings to permanent oxygen-minimum zones, proposing that mothers may select low-oxygen refuges to shield pups from predators while providing plankton-rich feeding layers. In Saleh Bay, 25 tagged whale sharks have shown strong site fidelity, spending most of their time within the bay. Konservasi Indonesia is pursuing a marine protected area in the bay’s northern sector—the first Indonesian reserve dedicated to whale-shark protection.
Data & Statistics
Conflicting Reports & Gaps
The source article describes the September 6, 2024 sighting as having already occurred, yet the date ledger classifies that date as “scheduled,” indicating uncertainty about whether the event has taken place. No additional independent verification is provided, leaving a gap in confirming the exact timing of the discovery.
