This short, silent video shares a few behind-the-scenes moments from the ”fish tornado” photograph, titled David and Goliath, taken in Cabo Pulmo, Baja California Sur, Mexico by photographer Octavio Aburto.
“As people have seen this image, I have been getting a lot of messages in my inbox and phone calls asking me “is this photo real?” And “how did you congregate all these fish in one place to take the photo?”
“My response to these questions has been this — of course it is real. Fish, as is the case with many other animals, have certain behaviors that they perform when they reproduce. For example, when monarch butterflies mate they travel hundreds of thousands of kilometers, crossing from Canada down through Mexico to form unbelievable congregations. Sea turtles also have unique reproduction behavior —some travel the entire Pacific just to return to the beaches where they originally hatched. Birds fly hundreds of kilometers to certain areas to nest as well. These behaviors are well known within terrestrial animals and within the scientific community we have also known of these behaviors with fish and other marine creatures for many years. In Cabo Pulmo for example, blacktip reef sharks and mobula rays also congregate in large numbers to mate during the winter season.
“Even after I explain this unique behavior and the spectacular spawning aggregations of fish that occur naturally, some people don’t believe this image is real.
“In some ways I think this photo, and others like it, force people to think about the environment and more specifically in this case the ocean, dwindling fish populations the health of marine ecosystems worldwide and our role in it all.”
You Are Your Microbes
Sure, you feel human, but that’s only mostly right. In and on your body, you’re outnumbered by ten times when it comes to microbes. And many of them have essential duties that we just couldn’t do by ourselves. Here’s a trip through your microbial inner universe … what we call the “microbiome”.
A lesson by Jessica Green and Karen Guillemin for TEDEducation.
Most people know Kew Gardens as home of the world’s largest living plant collection but are not aware that it is also the location of an internationally important botanical research and educational institution. Going beyond the gardens as we know them, Lonelyleap produced two films for 2012’s Tropical Extravaganza Festival which showcase the behind the scenes work of Kew’s scientists whilst also exploring two of the festival’s themes, Earth and Air.
The first in the series explores the importance of fungi to all plants and ultimately all life on Earth through several members of the Mycology Department committed to the conservation and exploration of fungi.
The second film in the series looks at the work of the the Millennium Seed Bank Partnership in Surrey, home to 10% of the world’s plant diversity, and how the Seed Conservation Department is helping to save wild plants and habitats for our future.
Oh, all of those green boxes! And in the second video: we especially liked seeing how the different seeds can get themselves around… not to mention all of the extremely important conservation efforts:
Found these both on Vimeo. Wonderful stuff.
