Unveiling the Mystery: Shifting Whale Shark Migration Patterns in the Arabian Sea and Ethical Encounters near Oman's Daymaniyat Islands
The vibrant coral reefs and diverse marine life of the Arabian Sea make it a haven for countless underwater wonders. Among these is the majestic whale shark, the largest fish species on Earth. These gentle giants have captivated scientists and tourists alike with their predictable seasonal movements. However, recent observations suggest a potential shift in their migration patterns, particularly near the pristine Daymaniyat Islands of Oman.
Established Whale Shark Migration Patterns in the Arabian Sea
Historically, whale sharks in the Arabian Sea followed a well-documented pattern documented in studies by Dr. Alistair Dove of the Marine Research Centre at the University of Salford, UK [1]. These seasonal movements are driven by the Southwest Monsoon. During the upwelling season (roughly May to September), plankton blooms fueled by nutrient-rich waters attract whale sharks to the area for feeding.
Shifting Patterns and New Discoveries in the Daymaniyat Islands
Recent observations by marine biologists at the Oman Aquarium and Marine Science Center near Oman's Daymaniyat Islands suggest a potential change in this established pattern [2]. Sightings of whale sharks outside the typical upwelling season raise intriguing questions: are whale sharks altering their migration routes due to environmental changes, or are we simply uncovering previously unknown aspects of their behavior?
Possible Causes for Shifting Whale Shark Migration
Several factors could be influencing this potential shift. Climate change and warming sea temperatures are known to impact ocean currents and plankton distribution, potentially altering the whalesharks' food sources. Additionally, increased fishing activities in traditional feeding grounds might be forcing these gentle giants to explore new areas.
Importance of Research and Conservation for Whale Sharks
Understanding these potential changes is crucial for the conservation of whale sharks. Continued research by institutions like the Oman Aquarium and Marine Science Center, along with international collaboration, will help us unravel the mysteries behind these shifting migration patterns.
Oman: A Leader in Whale Shark Research and Conservation
Oman has emerged as a leader in whale shark research and conservation efforts. The establishment of Marine Protected Areas (MPAs) like the Daymaniyat Islands provides safe havens for these magnificent creatures. Responsible tourism practices, such as regulated snorkeling trips with whale sharks, can generate revenue for conservation initiatives while fostering appreciation for these gentle giants.
The Daymaniyat Islands: A Paradise for Ethical Whale Shark Encounters
The Daymaniyat Islands, located off the coast of Muscat, Oman, offer a unique opportunity to witness these majestic creatures in their natural habitat. With its crystal-clear waters and thriving coral reefs, the islands are a designated MPA, ensuring a protected environment for whale sharks and other marine life.

Hands Signals to know when scuba diving
Ask any diver what they enjoy about scuba diving. Most will describe the absolute peace and tranquility of being at depth. Some will discuss the intense pleasure of not having to speak to anyone. So… how do you communicate with your buddies, dive master and other divers during a dive? Hand signals are the most common form of underwater communication. Let’s take a look at some of the most important ones to know.
OK / Are you okay?
The OK signal is the most important signal when it comes to diving. The ok is both a question and an answer. Join the thumb and index fingers while extending your third, fourth and fifth finger. The thumbs up signal indicates to go upwards or the end of a dive.
There's a problem
Have your palm flat and slowly move your hand from side to side, followed by where the problem is. Whether it's equalizing, your weight belt or something else, pointing out where the problem is will help your dive master, instructor or buddy to know what the issue is.
OK and problem at the surface
An OK at the surface is done by joining your hands above your head and can be used to signal the boat or lookout that you’re doing OK. This can also be done using one hand depending how far you are from the boat or shore. A problem at the surface is signaled by waving both hands and yelling ‘help.’
Thumbs up or down
Thumbs up can signal to ascend or the end of a dive. When you see this signal, you should also signal thumbs up to show that you’ve understood it’s time to ascend. A thumbs down is used to signal that the diver should descend.
Look at me or look over there
A scuba instructor will point at their eyes then at themselves to show students that they should look at what they’re about to demonstrate. A dive master during a fun dive may point at their eyes then in a direction to show that people should look in that direction.
Level off or stay at my level
Used to tell other divers to maintain their depth. It’s commonly used when you’ve reached your planned maximum depth or to tell divers to hold their depth for safety reasons. Extend your palm and move it slowly from side to side horizontally.
Buddy up
If you’re too far from your buddy, you may be asked to buddy up. This is done by using both index fingers and placing them close together.
Safety stop
A three minute safety stop at five meters is demonstrated by a flat open hand with your other hand below it indicating three. This means that divers should level off and start their safety stop.
Decompression
The deco signal can be done by either raising a pinky or raising a pinky and thumb. This signal is used in the event that a diver has passed their no-decompression limit and to communicate the need for an extra safety stop.
Low on air
Once you’ve reached 50 bar or go into the red on your gauge, you should signal to all other divers that you are low on air. This is done by placing a fist in front of your chest.
Out of air
In the unlikely event that you run out of air during a dive and other buddies are close by. You can signal you have run out of air by moving a flat hand across your throat which indicates your air supply has been cut off. Your buddy should then give you their alternate and you can start to ascend.
How much air do you have?
Your dive master and buddies may ask you how much air you have during a dive so you can adjust your dive depending on how much air the group has left. This is done by placing your index and middle finger into the palm of your other hand and tapping. To signal half a tank, form a time-out with your hands, 50 bar is done with a closed fist. Each additional 10 bar is indicated with the fingers on your other hand.
Stop/hold
You may be asked to stop or hold a position. To indicate this, hold a flat hand pointing forward or hold your forearm up and make a closed fist.
Come here
An open hand and moving your fingers towards yourself in a beckoning motion is used to signal to other divers to come here.
Now we've taken a look at some of the most popular underwater hand signals. What's your favourite one to use during a dive?
Snorkeling vs scuba diving: which is better?
The long debated question: scuba diving vs snorkeling, which is better?
Snorkeling is a popular activity whereby the person swims at the surface with a mask, snorkel and fins. While diving, you have added equipment including a BCD (buoyancy control device), tank, dive computer, wetsuit and weights. Using this equipment, you can go down to a given depth. On a Discover Scuba Dive, the maximum depth is 12 meters, Open Water Divers can reach 18 meters and Advanced Open Water Divers can plunge even further to a depth of 30 meters.
Snorkeling at Daymaniyat Islands
You can snorkel with little experience of being in the water. Whereas, diving can take some theory and practical experience before getting the hang of it. If you aren’t confident in the water, you can wear a life jacket to keep you afloat while you snorkel. It’s also possible to gain experience snorkeling to build your confidence before going diving. You don’t require a certification and snorkeling can be done nearly everywhere. On the other hand, diving requires you to get certified and when you dive in a new place you should ideally dive with a professional diver to be on hand at all times to act as a guide.
Scuba Diving in Oman
To start scuba diving, it’s important that you have the right equipment and perform pre-dive safety checks. You need to learn the theory behind diving safely and then put it into practice. For instance, how to perform safety stops for three minutes at five meters, conduct buddy checks, and be able to remain neutrally buoyant. While this sounds complex, divers from their second dive are able to do this successfully.
Diving allows you to immerse yourself in the underwater world for an extended period of time. Most snorkelers can get tired easily and will remain in the water for shorter than an average dive. While it takes longer to start to dive and is more expensive, the rewards are immense. When it comes down to it, when comparing snorkeling vs diving, it will mostly depend on personal preference.

5 types of sharks you can dive with in Oman
5 types of sharks you can dive with in Oman
Diving with sharks is an amazing experience. Most sharks are scared of humans and will swim away as soon as they see us. You can spot up to 10 species of sharks around Oman but let’s take a look at some of the most popular:
Blacktip Reef Shark
The blacktip reef shark is a very skittish shark which poses no threat to humans. They can range from 1 to 3 meters in length. One of the most popular sharks to see while diving in Oman, you can find them at Seahorse Bay in Bandar Khayran and throughout the dive sites at Daymaniyat Islands.
Whitetip Reef Shark
The whitetip reef shark is the most common shark to be found around the Arabian Gulf. You can usually spot them resting in caves. These sharks hunt at night so during the day, it's easy to find them resting in dark places. Average length is roughly 1.25 meters.
Zebra Shark
Zebra sharks, otherwise known as Leopard sharks, live at Daymaniyat Islands. They are truly beautiful, with a long slender body, and an equally long tail. You can find them while resting on a sandy bottom. Leopard sharks eat clams, fish eggs, and shrimp and pose no threat to humans.
Whale Shark
Whale sharks are actually not whales at all and are actually a type of filter-feeder shark. From July to September, it’s common to find whale sharks at Daymaniyat Islands and Al Fahal Island. You can spot them while diving and snorkeling as they use their mouths to filter plankton from the water and remain close to the surface.
Oman Bullhead Shark
The Oman Bullhead Shark lives around the central coast of Oman and Pakistan. The average length is 56cm. The chance of seeing an Oman Bullhead Shark while diving is very rare, but some divers have reported spotting these majestic sharks during a dive. Sadly, they caught as bycatch by fisherman and as a result, their population is significantly declining.
Seeing a shark during a dive is an exhilarating experience for even the most accomplished diver. So what are you waiting for? Book your dives today.

Whale Shark season in Oman!
Whale sharks are unquestionably the most powerful fish in the ocean, with the largest reaching 12 meters in length and weighing up to 20 tons. (This implies they’re not just the world’s largest fish, but also the world’s largest vertebrates, with the exception of great whales.) Despite their enormous size, whale sharks are perfectly harmless to humans; they are filter feeders, and sieve small plankton from the water.
Where can I see Whale sharks in Oman
Daymaniyat Islands is one of the best spots in Oman for whale shark snorkeling and diving.
That’s because the gigantic fish congregate in large numbers along Muscats coastline every summer Whaleshark season is between September to November.
The sharks and their pups migrate south to the warmer waters of the southern hemisphere in search of many fish eggs, shrimp, copepods, and other little morsels. During this period, there is a very good chance of an encounter.
Swimming and snorkeling with Whale sharks
The Daymaniyat Islands and Al Fahal Island:
are two of the most well-known places in Oman for seeing the gentle giants up close.
