How do Corals form new Species?

How do corals evolve into separate species when their larvae can drift around the ocean over extremely long distances?

Motorboat noise halves reef fish survival rate

Noise from passing motorboats increases stress levels in young coral reef fish and reduces their ability to flee from predators - causing more than twice as many to be killed.
Basking shark, Cetorhinus maximus

Basking shark mystery solved

Once thought of as a strictly cool-water species, basking sharks migrate to tropical waters each winter, according to research published in the June 2009...

Ocean bacteria “pumped-up” by dying plankton

Scientists have discovered a surprising new short-circuit to the biological pump. They found that sinking particles of stressed and dying phytoplankton release chemicals that...
Cuttlefish

Stealthy cuttlefish use electric cloaking

Cuttlefish are renown for their tremendous camouflage capabilities - changing the colour and texture of their skin to match their surroundings. They have another weapon in their hide and seek armoury though - electric cloaking.
Pacific blue-fin tuna

How warm-bodied tuna hearts keep pumping in killer cold

When tunas dive down to cold depths their body temperature stays warm but their heart temperature can fall by 15 degrees within minutes. The heart is chilled because it receives blood directly from the gills which mirrors water temperature. This clearly imposes stress upon the heart but it keeps beating, despite the temperature change. In most other animals the heart would stop.

Glue that stays sticky when wet is inspired by mussels

Using a protein produced by mussels, researchers have created a reversible synthetic glue that not only can bond securely underwater - but also may be turned on and off with electricity.

Scientists unveil first maps of deep sea corals

Proposed marine protected areas will cover just 30% of the UK’s deep sea coral reefs and 3% of the sponge fields, according to the first-ever set of maps detailing where vulnerable deep-sea habitats are likely to be found in the North East Atlantic.
