The juvenile in its party clothesThe sweetlips is a fast grower. In its juvenile stages, it is about 2.5cm in length but then will quickly grow to about 60cm. Along with this vast change in size, it also changes its entire colour scheme. It starts as a reddish/brown base with black-ringed white spots which then change to brown spots, which increase in number depending on age, over a white base

However, its most distinguishing feature is its swimming style while still a juvenile. Best described as a drunk partygoer wearing clothes that are much too big, it 'flaps' about using its dorsal fins with an undulated body. This style is meant to mimic flatworms which are noxious and unpalatable to predators. Another unique talent of some members of this species is its ability to 'grunt' by grinding its teeth, the sound is them amplified by its swimbladder.

Arguably the cutest fish in the ocean in its juvenile form, other fish watch and wish they could party as hard!


The yellow boxfish is quite a hard one to spot despite its unique shape and bright colour. This is because of their size being about the same as a pea at its smallest. Certain types can, however, grow as big as a football.

Like most other brightly coloured animals, its colour scheme is meant to warn off other animals as this little critter is highly poisonous and can release toxic proteins from its skin if threatened. This protein is so poisonous that it has the potential to kill all animals around it and wipe out an entire aquarium should it find itself unlucky enough to be in one. So don't buy them!

Its habitat is always amongst rocks and coral and its diet mainly consists of algae, worms and small fish. They also enjoy shrimp and crab too!

]Kiss me quick!    Plenty of room in the boot

Odd fact:  Mercedes-Benz designed a concept car based on the boxfish due to its aerodynamic design and skeletal strength - Plenty of room in the boot


These teeny-tiny little critters are, in a nutshell, the foundation of the food chain for the ocean world. Without them, there would not be much to see in the ocean even though you can't see them yourself.

They are more than just food though, they also are huge carbon dioxide absorbers accounting for about a third of all produced by us dirty humans. Pretty impressive. They live in the upper layers of the ocean where they produce organic compounds via photosynthesis. They actually account for half of all photosynthesis done on the planet. Even more impressive!

Their name comes from the Greek words meaning python (plant) and planktos (drifter/wanderer). Depending on which particular strand of phytoplankton is present, it changes the colour of the water. Here in Koh tao we get a green tint. If there is enough of them, you can even see them from space! Super impresive!!

Sunshine Divers is located at the Southern part of Koh Tao, the more relaxed, chilled and beautiful area which is called Chalok Baan Kao. The direct access to the beach, the chilled atmosphere, the beautiful rock formation "Buddha rock" and off course the relaxed atmosphere at Sunshine Divers is what most people attract to this location.

Chalok Baan Kao is far away from the busy and touristic Sairee Beach, but close enough to go there in about a 5 minute drive by either taxi or motorbike. Even better, you don't actually have to leave because in the last few years nice little restaurants found their way to this side of the island like healthy food boutique restaurants, luxury dining, lounge bar etc.. The famous Buddha Rock at the left end side of the bay is close to one of the more 'private' beaches of Chalok Baan called Freedom Beach and is one of the most picture taken shots.

If you scuba dive at Sunshine Divers we have a beach classroom directly on the beach which allows you to enjoy the view but also enjoy the cool stories about diving from your Instructor!

Hope to see you soon!



The PADI Bubblemaker program has been developed to offer anyone over the age of 8 years to participate in blowing bubbles using SCUBA underwater to a maximum depth of 2m.  This program can be conducted in either a pool or confined open water environment where conditions are calm.

Recently young 8 year old Vincent participated in the PADI Bubblemaker program, where he was instructed by Thomas Pommerin. Starting off at the beautiful dive site around Koh Nang Yuan called Japanese Gardens, Vincent observed several types of tropical fish including Butterfly fish, Angelfish, Sargent Majors and the infamous Triggerfish.  Vincent's father Stephan joined in with his Son to share the amazing experience.

To add further fun and games to this program Thomas introduced the Underwater Fizbee, which added value to the training especially for bouyancy control.

Anna, Yase and Pedro were drawn to Koh Tao to enjoy the beautiful beaches and explore the underwater world through Scuba Diving.

Anna & Yase were recommended by friends to come to Sunshine Divers and learn to take their PADI Open Water Diver course course. Pedro was walking by the dive shop - stopped and enquired about the program and decided to sign up and learn to dive. During the course, they learned the fundamentals of diving from getting geared up and buddy checking, the physiology and physics of diving along with planning their dives using the RDP and simply just having fun!!!

We look forward to your return to continue your diving with us at Sunshine or during your further travels worldwide - explore the many underwater environments.

Want to learn more about connecting items, lifting items and just in general how to tie KNOTS? The PADI Search and Recovery Specialty course, which is now incorporated in the PADI Divemaster Program as a workshop, helps teach you the basic knots that are useful when traveling or working on boats.

The Bowline, Sheet-bend and two-half hitches are useful knots for several situations. In particular when you need to attach a fender or a tyre to the side of the boat to prevent the boat from damages whilst docking.  Along with learning how to tie knots during the Search and Recovery Program you also learn several search patterns to find missing items. If these items are too heavy to lift we use special lifting devices to bring the object to the surface if it weighs more than 4 kg.

Rebecca practices the bowline knot during her Search and Recovery workshop of her Divemaster Program.
