The Mimic Octopus

Mimic Octopus a.k.a Thaumoctopus mimicus

The mimic octopus is a fascinating and unique creature that has gained worldwide attention for its incredible ability to change its appearance to mimic other animals. This fascinating creature, scientifically known as Thaumoctopus mimicus, certainly lives up to its name. Derived from the Greek word “thauma” meaning “marvelous”. This charming creature is truly a master of disguise. It can mimic the appearance and movements of other animals, such as sea snakes, flounder, stingrays, jawfish, snake eels, and even lionfish.

Marinefacts

The mimic octopus is found in the waters of the Indo-Pacific, where it employs its mimicry abilities as a survival strategy to elude potential predators and capture prey. Mimic octopuses use mimicry as a defensive mechanism, predominantly during feeding. These organisms engage in diurnal foraging activities within exposed sandy areas, rendering them susceptible to potential predation. This phenomenon could explain the prevalence of poisonous and venomous marine organisms in mimicry.

The mimic octopus is exceptionally intelligent, particularly to its predators. The octopus learns which animals annoy its predators and assumes their form to repel potential danger. When bothered by damselfish, for instance, the mimic octopus takes the form of a sea snake that preys on damselfish.

But the mimic octopus is not just a master of disguise. It is also a skilled escape artist. When threatened, it can use its flexible body to squeeze through tiny spaces and disappear into the safety of the surrounding coral reefs.

The Challenges Mimic Octopus Face

While the mimic octopus is a master of disguise, it unfortunately faces threats from human activities such as overfishing and pollution. We must take action to preserve the natural habitat of this fantastic creature. The mimic octopus is a remarkable animal showcasing the astonishing diversity of life in our oceans. Its ability to mimic other animals is a testament to the adaptability and ingenuity of nature. We must do our part to protect this unique creature and the fragile ecosystems it calls home.

Incredible Manta Rays in Paradise

Incredible Manta Rays in Paradise

Manta rays are one of the world’s most exotic marine creatures! They are the largest rays and are highly intelligent. Mantas are found in tropical, sub-tropical and temperate waters around the globe.

There are two kinds of Mantas: The (pelagic) giant oceanic manta ray (Manta birostris), and the (coastal) reef manta ray (Manta alfredi).

Actually, a 2017 taxonomy study found that mantas are actually mobula rays (aka devil rays) – so Giant manta would be Mobula birostris, and Reef manta, Mobula alfredi – but everyone knows them as mantas 🙂

Manta rays in Indonesia

In 2014, the Indonesian government placed a country-wide ban on fishing and trade in Manta rays based on the simple fact that Mantas are worth a lot more in terms of tourist dollars than in fish markets. The estimated value of a single Manta ray over its lifetime is estimated to be USD1 million vs. USD40-500 when caught and killed.

In December 2020, the International Union for the Conservation of Nature (IUCN) changed the conservation status of the Giant Manta rays from Vulnerable to Endangered on the Red List of Threatened Species.

Scuba divers usually encounter Mantas at their feeding locations. They have several creative feeding techniques ranging from doing repeated somersaults to stay in one spot that’s packed with krill, or chain-feeding where they follow each other in a circle, mouths open, to create a cyclone effect, trapping their food in the spiral.

Where to Find Manta Rays

The four main locations to see Manta rays in Indonesia are:

Manta Point, SW Nusa Penida (just off mainland Bali)
We are very lucky to see Manta rays year-round at Bali’s Manta Point. It is genuinely rare to dive here and not see them 🙂 In season (June-October), you may also see the weird-but-wonderful Southern sunfish, Mola alexandrini (known locally as Mola-Mola) and other pelagics such as tuna and Tiger mackerel.

Komodo National Park
Diving here is year-round; the best months to see Manta rays are during the rainy season from late November to February.

The Alor archipelago
Also known for sightings of Eagle rays as well as Mantas, plus sharks, Dog-tooth tuna and other pelagics.

Raja Ampat, West Papua
During the October to March rainy season, although visibility is lower, the water is rich with nutrients meaning you are likely to see more Mantas 🙂

If the above has whet your appetite and, like so many of our ‘Bali & Beyond’ guests, you can’t wait to start planning – please contact your friendly AMD-B Dive Travel Consultant on Tours@AquaMarineDiving.com today to start YOUR planning!

Komodo

Scuba Diving in Komodo National Park

Komodo National Park comprises the area’s three major islands: Komodo, Rinca, Padar and many smaller islands, the macro areas of Sangeang volcano and Sumbawa, and the barrier reef of Moyo Island.

Komodo and surrounding islands are located in the straits within the Lesser Sunda Islands between Sumba and Flores. Designated a UNESCO World Heritage site in 1991, the islands have a dry savannah landscape with pockets of thorny green vegetation, white and red sandy beaches, and lagoons for swimming and snorkelling.

In addition to the spectacular diving, Komodo National Park is home to the world’s largest lizard, the Komodo Dragon (Varanus komodoensis). Komodo dragons are endemic to eastern Indonesia and mainly found on the islands of Flores and Komodo. In 2021, the Komodo dragon was entered on the International Union for Conservation of Nature (IUCN) ‘Endangered’ list. This means it has a “high risk of extinction”.

Diving Komodo National Park

Being part of the Coral Triangle, Komodo National park offers some of the richest marine biodiversity on Earth.

Liveaboard diving is the most popular choice due to the distance between dive sites. Komodo’s northern sites are sometimes subject to strong currents but offer the chance to see schooling White-tip and Grey reef sharks, large schools of Giant and Blue-fin trevally, Big eye jacks, different species of turtles, even dolphins and dugongs. At quieter times, massive Napoleon wrasse in good numbers and Eagle rays come in from the blue.

In the south is the world-famous site Cannibal Rock in Horseshoe Bay, Rinca, home to some rare nudibranchs, several species and colours of Rhinopias, and a host of frogfish.

There are several Manta aggregation sites where divers can fly with literally squadrons of these magnificent creatures.

Seasons and Dive Conditions in Komodo National Park

Dry Season is April to November and is considered the best time to dive here.

However Wet Season ie: north-east monsoon (December to February) is also Manta Season 🙂 but can have reduced visibility.
Late November usually gives less rough seas but plenty of Manta sightings.

January to March: The northern dive sites become quite rough; consequently some land-based dive centres close at this time. If this is the only time available to you, AquaMarine suggests taking a liveaboard to visit southern dive sites. Our Dive Travel Consultants can help you with this.

Some of Komodo’s dive sites can have challenging currents; eg: Karang Makassar (Manta Point) so AquaMarine advises you refresh or upgrade your skills before heading over there to ensure you maximise your enjoyment.

How to reach Komodo National Park

There are liveaboards offering the round-trip between Bali and Komodo National Park.

Otherwise, coming from overseas, you would fly into Bali or Jakarta and then catch a domestic flight to Labuan Bajo. From there you either join a liveaboard or use local dive centres and resorts to explore nearby dive sites. In addition, there is a dive centre on Sebayur Island which is within the National Park.

On off-gassing days, we can arrange visits to see the actual Komodo dragons: Imagine 3m/10ft and 150lbs/70kgs of lizard! (The largest verified specimen was 366lbs/166kgs…) Don’t let their bulky appearance fool you as they can sprint up to 12mph/20km/h. They can dive to 15ft/4.5m and, when young, use their massive claws to climb trees. To catch out-of-reach prey, they stand on their hind legs and use their tail as support.

If you’re ready to experience Komodo National Park – or elsewhere in Indonesia! please contact AMD-B’s ‘Beyond Bali’ Dive Travel Consultants today on.

As always, they will be more than happy to offer recommendations and make arrangements to suit your preferences!
