5 Fascinating Facts About Manta RaysFeb 22 2025 | | Posted by Noey Widiarsa |
If you're planning a trip to Nusa Lembongan, one of the most breathtaking islands in Bali, Indonesia, then you might have already heard about the famous manta rays that inhabit its waters. These magnificent creatures are one of the biggest highlights of the island, attracting divers and snorkelers from all over the world. However, before you embark on your adventure, there are a few fascinating facts about manta rays that will make your experience even more magical.
Manta rays are gigantic! They belong to the family Mobulidae, and they are among the largest species of rays in the ocean. The two main species, the reef manta ray (Mobula alfredi) and the giant oceanic manta ray (Mobula birostris) can reach impressive sizes.
Manta rays are very large, but they are harmless to humans, which is why many people want to interact with them. Unlike stingrays, they do not have venomous barbs on their tails, making them safe to swim alongside. Their sheer size and graceful movements make them one of the most mesmerizing creatures you will ever encounter in the ocean.
An interesting fact about manta rays is that they are considered the smartest fish in the ocean. Scientists have discovered they have the largest brain-to-body ratio of any fish species. Their brains are ten times larger than that of a whale shark.
This high level of intelligence is reflected in their behavior. Manta rays are curious and playful, often interacting with divers and swimmers. They also display signs of self-awareness, an ability that only a few marine animals possess. Studies suggest that manta rays are capable of recognizing themselves in mirrors, a cognitive skill shared by dolphins, elephants, and great apes.
When you see them up close in Nusa Lembongan, don't be surprised if they come near you out of curiosity. Unlike many marine creatures that are shy or fearful of humans, manta rays often seem to enjoy human presence and may even perform graceful flips and loops as they glide through the water.
One of the most interesting behaviors of manta rays is their use of cleaning stations. These are specific coral reef areas where small cleaner fish, such as wrasses and cleaner shrimp, remove parasites, dead skin, and bacteria from the manta rays' bodies.
In Nusa Lembongan and nearby Nusa Penida, there are many natural cleaning stations where manta rays gather. They often line up and wait their turn as the small fish clean their bodies, gills, and even the inside of their mouths!
This behavior is crucial for their health, as it helps prevent infections and keeps their skin smooth and free of parasites. For divers and snorkelers, witnessing this cleaning ritual is a fascinating experience. It is also an excellent opportunity to observe manta rays up close, as they tend to stay still while being cleaned.
Although they are huge, manta rays have a diet that consists only of tiny plankton. They are filter feeders, meaning they swim with their large, open mouths to scoop up microscopic plankton and small crustaceans from the water.
Unlike sharks or other large marine predators, manta rays have no teeth to chew their food. Instead, they use specialized gill rakers to trap plankton while expelling excess water. They sometimes perform looping acrobatics, spinning in circles to gather more food efficiently.
If you're snorkeling or diving in Manta Bay or Manta Point in Nusa Lembongan, you might witness groups of manta rays feeding together in a beautiful, coordinated dance. Watching them glide gracefully while feeding is one of the most spectacular sights in the underwater world.
Despite their beauty and importance in the marine ecosystem, manta rays are classified as vulnerable due to threats from human activities.
Some of the biggest dangers manta rays face include:
Luckily, in Indonesia, manta rays are legally protected. In 2014, Indonesia created the world's largest manta ray sanctuary, covering over 6 million square kilometers of ocean. This has helped conserve their population and ensure that places like Nusa Lembongan remain one of the best destinations in the world to see manta rays in their natural habitat.
Now that you know these five fascinating facts about manta rays, your visit to Nusa Lembongan will be even more meaningful. From their massive size and remarkable intelligence to their unique feeding and cleaning behaviors, manta rays are truly one of the ocean's most extraordinary creatures.
