Watch the miraculous journey of infant sea turtles as these tiny animals run the gauntlet of predators and harsh conditions. Then, in numbers, see how human behavior has made their tough lives even more challenging.
Lady of Orda Cave by Natalia Avseenko and Phototeam.PRO
Two-time world champion free diver Natalia Avseenko ventured deep into Ordynskaya Cave in Perm, Russia… one of the longest and biggest underwater gypsum caves in the world, dressed as the mythical Lady of the Cave, a spirit who protects divers inside the “natural cathedral”.
30 seconds of breathtaking awe at physics – watch a water droplet bounce in ultra-slow-motion. Then, see 7 more everyday things in mesmerizing slow motion.
Who knew water could bounce on water?!?
Surface tension is amazing. Phenomena like this are dependent on the size of the drop, of course, so that the mechanical force of falling and bouncing doesn’t overcome the hydrogen bonding that keeps the droplet/surface intact.
These Glaucilla marginata are blue sea slugs or nudibranches — soft-bodied, marine gastropod mollusks, according to wikipedia — from the east coast of Australia, but they can also be found along the east and south coast of South Africa, European waters, and Mozambique. The narrator also mentions that they eat “blue bottle” jellyfish, as they are immune to the venom.
An 86-year-old Yorkshire man, Brendon Grimshaw may have lived alone for many years on the tiny island paradise of Moyenne in the Seychelles in the middle of the Indian Ocean since he bought it in 1962 for £8000, but he is rarely lonely.
For Brendon has spent the years reintroducing the indigenous giant tortoise to Moyenne and now shares the island with 120 of the magnificent creatures, on one of the world’s smallest national parks.
The BBC’s Simon Reeve went to visit him.
Once a hideaway for pirates, the island is now a paradise of accidental conservation! But it took a lot of work in the last 40 years to change it.
He hired his own Man Friday, a Seychellois called Rene Lafortune, who helped him transform Moyenne.
Together they planted palm trees, mango and paw-paw.
They saved rainwater and pumped it up the hillside by hand, or rowed back to the main island to collect a barrel of fresh water.
It was backbreaking, exhausting work. ‘My hands were covered in blisters,’ said Brendon…
Slowly the trees grew and fruited, and eventually water, electricity and a phone cable were piped across from Mahe.
Brendon also encouraged around 2,000 native birds back to the island by feeding them. Forty years very well-spent.
Many species interact in the wild, most often as predator and prey. But recent encounters between humpback whales and bottlenose dolphins reveal a playful side to interspecies interaction. In two different locations in Hawaii, scientists watched as dolphins “rode” the heads of whales: the whales lifted the dolphins up and out of the water, and then the dolphins slid back down. The two species seemed to cooperate in the activity, and neither displayed signs of aggression or distress. Whales and dolphins in Hawaiian waters often interact, but playful social activity such as this is extremely rare between species.
