Lionfish is creature of the month

Lionfish is creature of the month | SCUBA News | Scoop.it
Lionfish can live 15 years and reach 45cm (17.7in) in length. They have several adaptations, the most dangerous being the venom contained in the dorsal fin rays that can be hazardous to divers. This venom can cause nausea, dizziness, breathing difficulties, and in some rare cases, limb paralysis and death but are only harmful if you come into contact with it. Juveniles also show a unique adaptation, they possess a tentacle above their eye sockets that is thought might be used to either attract prey or in sexual selection.

At 9 foot long, not including the tail, tiger shark (Galeocerdo cuvier) Harry Lindo is not exactly on the small side.  It’s not Harry’s size that is exciti
SCUBA Travel's insight:

 In just over 3 years Harry swam over 44,000 kilometres – that’s more than the circumference of the Earth (just over 40,000 kilometres).  Harry’s track is the longest recorded for a tiger shark, and probably the longest ever published for any shark species.

Diving Centres in Indonesia: Sulawesi, Sumatra, Raja Ampat - SCUBA Travel

Diving Centres in Indonesia: Sulawesi, Sumatra, Raja Ampat - SCUBA Travel | SCUBA News | Scoop.it
Indonesia comprises over 17000 islands lying between the Indian and Pacific Oceans: it is the world's largest archipelago. Six thousand of these islands are inhabited.
SCUBA Travel's insight:

Indonesia is in the coral triangle, so called for the many different species of hard coral found here. Nutrient-rich currents from the Pacific and Indian oceans collide, providing planktonic food for corals, fish larvae and giant filter feeders like manta rays. The diving here is world class.

SCUBA Divers cause coral disease and damage - it's official - SCUBA News

SCUBA Divers cause coral disease and damage - it's official - SCUBA News | SCUBA News | Scoop.it
SCUBA diving and snorkelling are amongst the fastest growing tourism sectors. The increasing numbers mean many more people are aware of the beauty and importance of the marine environment, but also puts a great strain on the coral. Not only is it damaged by inexperienced divers kicking it and pollution from boats and hotels, research also shows that coral is much more likely to become diseased in highly dived areas.
SCUBA Travel's insight:

Researchers  compared levels of coral diseases at high and low use dive sites around the area of Koh Tao in Thailand. The scientists surveyed 10,499 corals at ten dive sites around the island. They found twice as many healthy corals at little-dived sites (79%) as they did at the more popular dive areas (45%).

So says an interesting article from the Pew Charitable Trusts on why shark management should be different to that of other fish. Sharks - not like other fish
Sharks are actually more like mammals in their life histories than fish.

SCUBA Travel's insight:

Sharks grow slowly, mature late in life and have few offspring. Unlike other bony fish which achieve sexual maturity at an early age, reproduce often, and have many offspring. 

For example, a female shark that produced 10 pups every two years for 20 years would add only about 100 individuals to the population. In contrast, a female swordfish could produce millions of offspring in her lifetime, and thousands could survive.

Elephant seals give measure dissolved oxygen more accurately than any other method.
SCUBA Travel's insight:

Diving almost continuously at great depth during most of the year, and covering large distance through remote areas of the Southern Ocean, Kerguelen elephant seals have proved to be a great alternative to other instruments for monitoring the oceans. The seal-derived measurements of oceanic dissolved oxygen give better results than other methods, according to new research.

Best Diving in the Maldives Islands - SCUBA Travel

Best Diving in the Maldives Islands - SCUBA Travel | SCUBA News | Scoop.it
SCUBA Travel's insight:

The 26 atolls (ring-shaped reefs) in the Maldives are home to 1192 islands. Tourism is strictly controlled: visitors must stay on registered tourist islands or on liveaboad boat. There are 85 resorts in the Maldives, but not all of them cater for divers. On those that don't you should be able to dive from a neighbouring resort. It's better to go full board as everything is very expensive, including equipment hire. July and August are cheaper, but the visibility is not as good. The serious diving resorts include Biyadoo - very good food as they grow their own fruit and vegetables and Elaidoo . There is one international airport in the Maldives, on Male.

The very hungry sea anemone

The very hungry sea anemone | SCUBA News | Scoop.it
The surprising culinary preferences of an abyssal sea anemone have been unveiled by a team of scientists from the National Oceanography Centre.
New time-lapse photography of the abyssal sea floor shows that this type of anemone can eat animals up to six times its weight and moves around the ocean floor by burrowing. The lead author of this study, Jennifer Durden, a Ph.D. student at the NOC, explained that these heavy meals can take the anemone up to 80 hours to digest.
