Two Australians created this container that collects plastic, paper, oil, fuel and detergent floating in the ocean. They want to implement it the middle of next year to clean up the sea worldwide. It seems a great idea. The only “but” as always is money, so they are raising funds to get to their goal. You can see their project and donationshere.
For the first time, researchers have found evidence that underwater ecosystems have pollinators that perform the same task as bees on land.
Just like their terrestrial cousins, grasses under the sea shed pollen to sexually reproduce. Until now, biologists assumed the marine plants relied on water alone to spread their genes far and wide. But the discovery of pollen-carrying ‘bees of the sea’ has changed all of that.
Over several years from 2009 to 2012, researchers from the National Autonomous University of Mexico filmed the spring nocturnal wanderings of crustaceans among beds of turtle seagrass, Thalassia testudinum.
Looking through the videos, they spotted more invertebrates visiting male pollen-bearing flowers than those that lacked pollen – just like bees hovering around pollen-producing plants on land.
“We saw all of these animals coming in, and then we saw some of them carrying pollen,” lead researcher Brigitta van Tussenbroek told New Scientist.
The concept was so new, they invented a new term to describe it: zoobenthophilous pollination. Before that, researchers had never predicted that animals were involved in pollinating marine plants.
400-year-old Greenland shark is the oldest vertebrate animal
She was born during the reign of James I, was a youngster when René Descartes set out his rules of thought and the great fire of London raged, saw out her adolescent years as George II ascended the throne, reached adulthood around the time that the American revolution kicked off, and lived through two world wars. Living to an estimated age of nearly 400 years, a female Greenland shark has set a new record for longevity, scientists have revealed.
And you’ll never guess how old she has to be before reaching sexual maturity…
In a news release earlier this month, the IUCN revealed that increasing anthropogenic pressures (such as fishing and boat strikes) have caused the rapid decline of whale shark populations and that they should now be considered as endangered.
The International Union for the Conservation of Nature (IUCN) is the world’s main authority on the conservation status of species. The IUCN Red List evaluates the extinction risk of thousands of species based on a precise set of criteria, and the resulting evaluation aims to convey the urgency of conservation of a species to the public and policy makers.
Previously, whale sharks were ‘vulnerable’ to extinction, but their status has now been updated to ‘endangered.’ Their numbers have more than halved over the last 75 years as these sharks continue to be fished and killed by ship propellers.
Dr. Simon Pierce and Dr. Brad Norman, two prominent whale shark scientists have spent decades studying the animals and have co-authored the assessment that led to IUCN’s update.
“In our recent assessment, it was established that numbers have decreased more than 50 per cent in three generations – which we estimate to be about 75 years,” Norman explained. “The numbers on a global scale are really concerning.”
The main stressor to these gentle giants is the intense fishing pressure in several countries, including China and Oman, especially for shark-fin soup. Some other nations such as India, the Philippines and Taiwan have started implementing conservation plans and have ended large-scale fishing of whale sharks. While these efforts are admirable, it is now really important to push for more regional protection in these countries and to push other countries to try to save this species.
Whale sharks have been hard to study and to keep track off as they are quite cryptic and disappear into the open ocean fairly quickly. However with the use of modern technology and tagging devices, it has become a lot easier to follow them, collect information on them, but also to realize what kind of threats they are facing.
The species is just one step away from being critically endangered, an IUCN listing that is very hard to come back from.
“We cannot sit back and fail to implement direct actions to minimize threats facing whale sharks at the global scale,” said Norman, “It is clear that this species is in trouble.”

The Okeanos Explorer has discovered a very cute octopus at a depth of 4,290 metres.
This is the deepest an octopus of this particular sub order of octopus has ever been seen.
The National Oceanic and Atmospheric Administration noted this is a completely unsubscribed species and perhaps not belonging to any specific genus. Highlighting how little we still know about the creatures in the depths of our oceans.
