The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task, it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain anymore so it eats it!
Ten percent of the big fish still remain. There are still some blue whales. There are still some krill in Antarctica. There are a few oysters in Chesapeake Bay. Half the coral reefs are still in pretty good shape, a jeweled belt around the middle of the planet. There's still time, but not a lot, to turn things around.
The Bahamas has mangrove nurseries, coral reefs, shallow sea grass beds, and deep oceanic trenches - all perfect ecosystems for sharks. Photographing multiple shark species in exquisite water was the assignment I had dreamed about from the start.
Coral reefs represent some of the world's most spectacular beauty spots, but they are also the foundation of marine life: without them many of the sea's most exquisite species will not survive.
Practically the whole world depends on coral reefs, so if the coral reefs get all killed, then the ocean will start going out of whack, and if the ocean goes out of whack, something might happen on land.
For a photographer, sharks are a stirring subject, possessing a perfect blend of grace and power. They have been sculpted by evolution and are ideally suited for whichever ecosystem they inhabit, from coral reefs to the open ocean.
That includes not cutting down the rain forest, and stop polluting the ocean because once we kill the coral reefs and the rain forest, this earth is toast.
I can mention many moments that were unforgettable and revelatory. But the most single revelatory three minutes was the first time I put on scuba gear and dived on a coral reef. It's just the unbelievable fact that you can move in three dimensions.
Ice ages have come and gone. Coral reefs have persisted.
Organisms don't think of CO2 as a poison. Plants and organisms that make shells, coral, think of it as a building block.
