Anemone City

Clownfish sea anemones usually live solitary lives. On many coral reefs there will normally be only one individual for each 50 to 100 meters, perhaps 10 to 20 meters of reef. But occasionally groups of up to several hundreds of clownfish sea anemones are found together within a small area in an assemblage we call anemone cities.

One is at Ras Muhammad close to the popular dive resort Sharm el Sheikh where it is but one of the many popular dive sites in the area and well visited by many divers being completely oblivious to the fact that they are diving on a rather unique and fragile structure.

Ecofieldtrips Pte Ltd is a Singapore based company which employs specialist biologists to cover the biology of rainforests, mangroves, seashores and coral reefs in the unspoilt ecosystems of Tioman Island, Sarawak and Langkawi, in Malaysia. School groups from Singapore, Malaysia, Hong Kong, Bangladesh, UK and Ireland come annually on the fieldtrips.

The “hands on” field experience and the knowledge and experience of EFT biologists ensures a better understanding of our wonderful ecosystems and how they are interrelated.

Salty Oceans

It would seem to be self-evident to use the adjective ‘salty’ in connection with the World’s oceans. Everybody knows that the oceans are salty. It is perhaps the first thing that comes to mind when we think of the oceans.

Not only has it importance for the heat transmission, for example, from the seas to the land and vice versa, and thus affecting global climate, but it is of the greatest importance on the types of life that have evolved in these waters.

Solo or not?

When divers run out of gas in open water it can only be down to two possible explanations. Either they haven’t been monitoring their pressure gauges and plainly run dry. Or they have suffered some equipment malfunction such as a regulator free flow or a split hose which are technical breakdowns that can happen even to the most conscientious, experienced and well trained diver.

Training agencies differ in the degree of self sufficiency training at recreational levels. Most of them instruct divers to, when in a situation where they run low or out of gas, to swim to their “buddy” and share gas from an alternate second stage, or octopus as it is widely known.
