aaa Southern Reefs, Netherlands Antilles islands

Southern reefs, Antilles islands



This reef encircles the whole island by a narrow band of coral reef. The island has 54km of coastline, which means there is a great deal of reef. There are thought to be around 80 good diving sites, with 6 considered amongst the best in the world.


On the southern side of the island, the sea floor falls away just 100m from the shore, which means that gentle slopes covered in coral, give way to incredible coral walls. Huge numbers of fish are all around, as well as bigger creatures off the coast.

Shark watching in the Bahamas

One of the few places in the world, where sharks are not being hunted to eradication, the Bahamas is a fantastic place to head to see wild sharks. There are thought to be quite a few sharks that live in the area year-round, but there are also many more which visits.

Tiger sharks, Caribbean reef shark, Great hammerhead shark, Bull shark, Lemon shark, Nurse shark, Oceanic white-tip shark and Silky sharks are all considered to be resident, however over 40 species have been spotted suggesting many other species visit at different times of the year. This includes several great white sharks which are tagged and have been tracked within these waters in the last few months.

Sian ka'an biosphere reserve, Yucatan Peninsula, Mexico



Bottlenose dolphin, Sea green turtle, Caribbean manatee, Central American Tapir, Forest condor or real condor, Jaguar, Howling monkey, Ocelote in Sian Ka’an, Western manatees can all be found in this reserve. 


The reserve is made up of tropical forests, mangroves, marshes and a large area of ocean.  The reserve’s name can be translated as gate of heaven. 


The reserve covers over 5000 Square km, Part of which is land and the rest is in the coral sea and includes a large area of coral reef.

Can the red sea teach us how to save the worlds corals?

The coral itself is actually usually quite a dull colour, the brilliant colours of coral reefs come from the algae that lives within its coral tissue. These algae’s are called Zooxanthellae and in return for their home, the algae supply most of the corals nutrients.

The problem, is that these algae are very sensitive to temperature changes, and so if the sea remains unusually warm or cold for more than a few days, the algae leaves the corals and this is called a bleaching. This bleaching has occurred more and more recently in the last few years.

As a result of this, it is feared, that up to 90% of the corals worldwide will be lost by 2050.

This is where the red sea corals become so interesting.

The red sea coral reef looks the same as any other reef, but it appears that there is a difference, that might be the key to saving reefs around the world

Just 2 years ago, researchers found some corals in the Gulf of Aqaba, a trench between Israel, Jordan and Egypt which could withstand higher temperatures for longer. Just 1 degree above normal, sustained for a week can be enough to cause bleaching. If the temperature does not fall quickly, the corals will die. Yet here, corals have been seen to survive temperature rises above 7 degrees. It is thought that these corals have developed these abilities because they regularly suffer large temperature changes.

If they can identify corals that have this ability, and translocate them into new reefs, they will cross-breed. As the heat resistant corals are heat resistant, they are likely to survive far longer and therefore be able to pass on their heat resistant trait into the whole reef.

Given the rapidly warming planet, we only have about 30 years to act. Apart from their own intrinsic value, coral reefs are also worth roughly $600,000 per square kilometre each year, through protecting coastlines, increased tourism, medication and a whole lot more effects.

This is a fantastic possible save for the worlds reefs, time will tell if it works.

New Australian study on reef in a no fishing zone, shows what can happen when reefs are untouched by humans

The reef in question – The Rowley Shoals, are an isolated archipelago about 260km off Australia’s north west coast.

What was found was incredible. Between its protection from fishing, its location and the shape of the reef it has sustained species long lost elsewhere.

Species of giant fish like humphead Maori wrasse and humphead Parrotfish (both growing to over 1.5m were a regular sight, despite the fact that globally they are threatened with extinction. Of particular excitement, across the long study, there was no discernible change in the quantity of these fish – even as they were seen less and less regularly elsewhere.

Efforts must be made to maintain reefs like this, in their unblemished state. These reefs are far more capable of dealing with environmental changes, and hopefully one day there will be a need to reseed reefs in more accessible parts of the world.

Australian Environmentalist groups want the UN to put the Great barrier reef on the ‘in danger list’, will the government listen?

While Australian government ministers are fighting hard against, there are increasing calls from Australian environmentalist groups for the great barrier reef to be added to the list of ecosystems in danger.

The great barrier reef is one of the true spectacles of the natural world, but we are in danger of loosing it forever.

It is frankly insane that this is still a discussion. Of course the great barrier reef is in danger.

Indeed, it is endangered by a number of things
