The Welsh government has now halted a public consultation process regarding controversial plans concerning a protected marine area in Cardigan Bay, home to many bottlenose dolphins.
Government officials have blamed "technical issues" and have said that the process would have to restart at a later date.
In a rare incident, a small flat fish is thought to have killed a whale after becoming stuck in the much larger creature's blowhole.
According to scientists, it is the first recorded incident of a pilot whale suffocating on a fish since 1581, and within weeks it is thought to have happened once again.
WDC, together with partner organisations, Marine Conservation Society and ClientEarth has lodged a complaint against the Welsh Government proposals to open up a protected marine area in Cardigan Bay to damaging scallop dredging activities.
Scallop dredging destroys almost everything and smashes the seabed life forms to pieces and quickly reduces a rich ecosystem to a sandy or muddy desert.
Conservationists and engineers in Brazil are battling to save marine wildlife from contamination following the collapse of a dam, which has led to the waters in the Rio Doce estuary to turn brown with toxic mud.
After the dam’s collapse, water containing iron-ore residue from the nearby Samarco mine entered the delicate ecosystem of the river, which flows out in to the Atlantic. The area is rich in marine life, including humpback whales and one of the world’s smallest dolphins, the franciscana.
Scientists in Chile are investigating what may have caused the death of 337 baleen whales, discovered in June washed up on beaches between the Gulf of Penas and Puerto Natales in a remote southern part of the country. The discovery was made after local authorities instigated a wider search after over 20 whales were found in April.
Scientists are trying to work out what caused the death of three young fin whales that were found washed up on remote beach in British Columbia.
A new dolphinarium has opened in Phuket, Thailand despite widespread opposition from both local campaigners and overseas.
Five dolphins and two seals are on display at the marine park. Despite assurances from the owner that the dolphins were born in captivity and came from the Ukraine, there is concern that they may have originated in Japan, where many dolphins are supplied to the captivity industry by the fishermen from the notorious annual drive hunts in Taiji.
The Aquarium had been trying to import 18 whales captured in Sea of Okhotsk, Russia, but the court initially denied a permit to do so on the grounds that the Aquarium had not met conditions required to approve its controversial plan.
