It is very common to see dolphins from the boat in Bunaken national park. We have 7 different kind of dolphins, however very rarely we can see them when diving, there are quite shy animals and they don’t like bubbles
It is the second time in one month that this happen! This time our guest Osgrid was the lucky one in Lekuan II dive site.
Top 12 Facts about Dolphins that you must know
1. Dolphins are mammals.
As all mammals, dolphins nurse their young from mammary glands.
2. Dolphins can swim up to 260 m. below the surface of the ocean.
However they are mainly shallow divers as they need to reach the surface to breathe.
3. Dolphins can stay up to 15 minutes under water.
They only do this some times as they usually stay only a few minutes diving before reaching the surface for air.
4. Dolphins use a technique called echolocation.
This technique uses the same principles of a radar, and it is used to find food and navigate.
5. Dolphins are social beings.
Dolphins live in groups and cooperate among each other for activities like getting food and calf rising.
6. Dolphins are Cetacenas.
There are 32 species of ocean dolphins and 5 species of river dolphins.
7. The largest dolphin is the Orca, also known as “killer whale”.
Orcas grow up to 6.1 meters long and they are named as whales because their size, but they really belong to the toothed cetacean family just like dolphins do.
8. The most popular dolphin is the “bottlenose dolphin”.
Bottlenose dolphins are the ones we have seen in tv series, movies and aquatic shows. Bottlenose dolphins can grow up to 2.5-2.8 meters.
9. Dolphins are warm-blooded.
As mammals, dolphins are warm blooded and their internal temperature is around 36 degrees. To conserve this temperature they are surrounded by a thick layer of fat called “blubber” just below the skin.
10. The botllenose dolphin brain weighs 1500-1600 grams.
While average human brain weighs 1200-1300 grs. This is not a conclusive evidence of dolphin intelligence as many other factors might be the cause of intelligence according to scientists.
11. Dolphins communicate efficiently.
Dolphins can make a unique signature whistle that may help individual dolphins recognize
each other, collaborate and perform several other kinds of communication.
12. Dolphins can swim 5 to 12 kilometers per hour.
We just wanted to share with you the great dives we had yesterday! How much fun we had and what incredible things we saw!
Our first dive we went to one of the most famous dive sites in Bunaken: Fukui.
Fukui is a sloping dive, completely covered with hard corals. You will see a dense foliose of branching hard corals and big hard coral colonies grouped together in areas. For marine life we have lots of fishes: Many schooling fishes: spade fishes, black snappers, blackfin barracuda, trevallys, sweetlips, large triggerfishes and garden eels. As for invertebrates we can find here: the main attraction to Fukui is the incredible Giant Clams!! They are incredible to see and nothing like you have ever seen! Please look below to the photos! Also, you will see here incredibly big barrel sponges.
Possible encounters in Fukui include: Great barracudas, giant sweetlips, Napoleon wrasse, bumphead
parrotfish. Eagle rays, mota mola, thresher shark and manta rays have been seen.
Yesterday at Fukui we had a very special dive: we saw a slowly passing spotted eagle ray! how nice was to see this gentile and graceful animal passing bye so slowly! It really gave us time to enjoy its beauty! Also, we saw the resident school of bat fish, with as many as 50 fish hanging out in the shallow water! Then, as we kept swimming in the shallow, we saw a really big Napoleon wrasse! What a beautiful animal this is!
For our second dive, we went to Likuan I, this is another of the “big hitters” here in Bunaken. It is another really famous dive with great beauty and impressive underwater topography. It consists of vertical, winding walls. Cracks & canyons. Often strong currents. Yesterday we had strong currents!! It is a dive sheltered from waves. Things that we can see here, fishes: Many huge schools of plankton-feeders: fusiliers, pyramid
butterfly fishes, banner fishes, and damsel fishes. In the invertebrates area: Giant barrel sponges, black coral, ascidians and gorgonians. The most spectacular thing about this site is the great number of Green turtles and hawksbill, whitetitp reef sharks, seasnakest groupers, large emperors, bumphead parrotfish, Napoleon wrasse, and trevallys.
Yesterday, we saw THREE EAGLE RAYS in formation, swimming very slowly and we had all the time to enjoy their graceful beauty! At the end of our dive we saw TWO REALLY BIG NAPOLEON WRASSE!! how big they were!!
