Every day around the world there are positive ocean news stories, from the latest marine science research, to evidence of animal populations recovering through conservation efforts. Here are our top 10 positive ocean news stories from our daily facebook feed from July 2020 to give you some #oceanoptimism.
Beluga Whales form complex social networks beyond family ties, much like human societies. They have a lifespan of 70 years, have highly developed vocal communications, and live within communities of hundreds and possibly thousands. They have support structures, cooperation and a culture where individuals bond with both close family and non-kin.

Dolphins learn foraging skills, not just from their mothers, but from their peers. Shelling is a tactic they use when prey hides inside large empty shells of giant sea snails. They use their beaks to bring these shells to the surface and then shake the trapped food into their mouths – like the last few crisps at the bottom of a packet.

Sea Turtles sometimes take the long way round when navigating between their feeding and mating grounds. GPS tracked Green Turtles in the Indian Ocean appear to swim much further than they need to using a rough mental map and a crude magnetic compass sense. Round trips can be up to 8000km.

New Zealand’s monster penguins that lived 60 million years ago had doppelgangers in Japan, the USA and Canada. Named ‘plotopterids’, their fossilised bones show they would have been up to 2 metres tall. Although resembling and living like penguins, they were related more to the boobies and gannets of today.

Whale Sharks have thousands of tiny teeth around their eyes. Each eye bulges out into the water and is protected by a cover that has about 3000 of these ‘dermal denticles’. The rest of its huge body is also covered in hard enamel scales that resemble teeth – great for protection, and arranged in a way that helps the shark swim faster.

The Giant Sunfish larva, which looks nothing like its adult form, has finally been identified through DNA analysis. The largest species, the Ocean Sun Fish, can grow over 4m, weigh over 2.5 tons, and can release up to 300 million eggs in one go. This larva is only 5mm big.

Giant Clam Fans
Giant Clams manipulate light to help their algae partners. Special cells containing nanoreflectors alter the wavelength of sunlight falling on its flesh. This protects them from harmful UV radiation, especially in shallow waters, and increases the photosynthetic activity of their symbionts.

The Kelp that lives off Scotland, Ireland & France dates back 16,000 years to the last ice age. Kelp plays a critical role in the health of Atlantic marine life. The discovery could help show how marine plant life survives extreme changes in climate.

Deep Sea Fans
A remarkable deep-sea fish virtually disappears by absorbing 99.5+% of light. The Pacific Blackdragon has a bioluminescent lure to attract prey. If not for their ultra-black skin and transparent, anti-reflective teeth, their reflection would scare prey away.
