Despite having a face that looks strangely like that of a disgruntled weasel, the Whitetip Reef Shark (Triaenodon obesus) is generally unaggressive toward humans who invade its environment. Although it often rests in caves during daylight hours, this species is probably the most commonly-encountered shark of the tropical Pacific. Indeed, for many divers and snorkellers, the phlegmatic Reef Whitetip is their only ambassador to sharkdom.
These beautiful cuttlefish get their name from the flamboyant pink, yellow and black ripples they make with their bodies when alarmed.
This small cuttlefish is just 8cm (3in) in length.
They are found in northern Australia and Indonesia.
A tropical species with limited distribution, it is found on the seabed in shallow waters.
Small fish and crustaceans.
Active in the day the cuttlefish uses vision to detect its prey. It’s capable of rapid colour change that might be used to confuse predators or prey.
Like other cephalopods, the flamboyant cuttlefish breeds once and then dies.
Today again awesome dives in Wori!!Mimic, long arm and coconut octopus, three painted frogfish, gunnard, ambon scorpion fish just to name few!!! Here some pictures!
It has been almost two weeks since we first time saw dugons and they are still in Ron’s point. We saw them in all the dives since that!! (not all the divers I have to say……but they are there!!). Today after half an hour dive they scared me just in front of me when I was looking close to a lizard!!They were two, one of them swam away after few minutes but the other one stayed with me for the rest of the dive. Sucking the sandy bottoms and swimming to the surface for air, gave me time to enjoy with this peaceful animal.
Here some pictures…..not quite good do, it is difficult to get good pictures of such a big animal with the macro lens…
Yesterday our guest Selina and our head guide John had the privilege of enjoy diving with a dugon in Ron’s point!! The dive start with three black tip sharks and after 20 min they spotted the dugon who stayed with them until they were low on air!! Great last day diving in Bunaken for Selina who did over 40 dives between Lembeh and Bunaken.
The dugong (Dugong dugon) is a large marine mammal, together with the manatees, is one of four living species of the order Sirenia.The dugong is the only strictly-marine herbivorous mammal, as all species of manatee utilise fresh water to some degree.
Like all modern sirenians, the dugong has a fusiform body with no dorsal fin or hind limbs, instead possessing paddle-like forelimbs used to manoeuvre. It is easily distinguished from the manatees by its fluked, dolphin-like tail, but also possesses a unique skull and teeth. The dugong is heavily dependent on seagrasses for subsistence and is thus restricted to the coastal habitats where they grow, with the largest dugong concentrations typically occurring in wide, shallow, protected areas such as bays, mangrove channels and the lee sides of large inshore islands.
The dugong has been hunted for thousands of years for its meat and oil, although dugong hunting also has great cultural significance throughout its range. The dugong’s current distribution is reduced and disjunct, and many populations are close to extinction. The IUCN lists the dugong as a species vulnerable to extinction.
