This is the blog homepage of the Facebook group "The Earth Story" (Click here to visit our Facebook group). “The Earth Story” are group of volunteers with backgrounds throughout the Earth Sciences. We cover all Earth sciences - oceanography, climatology, geology, geophysics and much, much more. Our articles combine the latest research, stunning photography, and basic knowledge of geosciences, and are written for everyone!
We hope you find us to be a unique home for learning about the Earth sciences, and we hope you enjoy!

natgeo Video by @jenniferhayesig A vulnerable sea turtle hatchling makes its way to the Gulf Stream in desperate search of weed cover to hide in. When sea turtles hatch they crawl across sand through a gauntlet of birds and mammals before they enter the water greeted by an ocean full of hungry predators. A very few lucky sea turtle hatchlings will survive long enough to find their way to floating rafts of algae called sargassum weed to hide in until they are big enough to fend for themselves. The sargassum canopies are critical to survival of these endangered sea turtles

natgeo Video by @tbfrost | Right in front of John F Kennedy's winter White House in Palm Beach, Florida, a friend took me on a walk and we stumbled upon a researcher who was checking sea turtle nests that had hatched to look for any little ones that hadn't escaped. We got lucky (so did the little turtles) and the researcher found 2 Baby loggerhead sea turtles , pulled them from the nest and sent them on their way, their first journey being a 40 foot dash to the sea. Several different species of sea turtles lay nests here but beach front properties with giant retaining walls to try and keep the sea at bay and landscaping / house lights left on all night are affecting the nesting success of sea turtles along this highly developed stretch of coastline. Despite how sad it makes me knowing humans are impacting wildlife like this - It is random mornings like these that make life so wonderful and this work worthwhile.

usinterior Run turtle, run! 🐢💨 On July 29, #PadreIsland National Seashore in #Texas had its last turtle release of the year, sending 184 baby Kemp's ridley sea turtles into the wild. In the spring and summer, nesting turtles are protected, examined and tagged @padreislandnps. Nests are moved to protected areas and monitored until they hatch. Then thousands of visitors come to see these hatchlings cruise into the ocean. They are popular events, and we can definitely see why! Video by #NationalPark Service.

natgeoVideo by @tbfrost and @melissalesh It turns out even baby crocodiles have an itch sometimes! But be careful , if you itch too hard you might take a tumble.
The mosquitoes in the swamp where this was filmed were awful, almost as bad as the far north , places like Canada and Alaska and Greenland, and as you can see they bothered the crocodiles too. This baby saltwater crocodile (crocodylus porosus) is only minutes old, just hatched out of its egg and climbed and clawed its way out of the earthen mound nest its mother made about 90 days earlier. Most saltwater crocodile nests have 40-60 eggs, this one had about that , though only 15 or so ever emerged. And of those 15 it is likely that only 1 will survive to adulthood. The rest will be picked off by birds, snakes, pigs, and even other crocodiles. It is a tough life and northern Australia is a harsh place. In many cases the mother crocodile will guard her nest until the baby crocs hatch. She knows they are ready when they start calling from inside the egg at which point she will help dig them from the nest and even carry them to the water in her mouth. It Is not uncommon for the mother croc to then spend two months with her offspring to protect them

fathomlesslife Octopus eggs hatching 🐙 The male octopus has a modified arm called the hectocotylus, which is about a meter long and holds rows of sperm. Depending on the species, he will either approach a receptive female and insert the arm into her oviduct or take off the arm and give it to her to store in her mantle for later. In the latter scenario, the female keeps the arm until she lays her eggs, at which time she takes the arm out and spreads the sperm over her eggs to fertilize them. The female meticulously cares for her eggs until they hatch, forgoing food the entire time. She blows currents across the eggs to keep them clean and protects them from predators. The eggs might incubate anywhere from two to 10 months, depending on the species and the water temperature. Once they hatch, they're on their own -- one source cites an estimated 1 percent survival rate for the giant Pacific octopus from hatchling to 10 millimeters. Depending on the species, some octopuses begin life as miniscule specks floating on the ocean's surface that drift down upon reaching a larger size, while some start out a bit bigger on the ocean's bottom.
