Marine biologists are celebrating new discoveries about the remarkable Anax sea cucumber, a keystone species featured in the latest installment of the Amazing Sansha documentary series. This cylindrical marine giant, reaching lengths exceeding most tropical reef fish, plays a vital role in maintaining ocean floor health across Asia's tropical waters.
Recent footage reveals how the creature's slow movements across coral sands create microhabitats for crustaceans and mollusks. "What appears passive is actually an ecological engine," explains Dr. Lin Wei, a marine ecologist at Hainan Ocean University. "The Anax's body structure and feeding patterns help recycle nutrients while providing mobile shelter for at least 17 documented species."
Researchers note increased sightings this year near the Paracel Islands, with underwater surveys showing a 12% population growth since 2023. Conservationists attribute this recovery to improved regional marine protection agreements and sustainable fishing practices adopted across Southeast Asian coastal communities.
The species' economic significance is gaining attention, with pharmaceutical companies studying its unique collagen properties for medical applications. Meanwhile, dive tourism operators report growing interest in "sea cucumber safaris" among eco-conscious travelers visiting the Philippines and Malaysian Borneo.
