- Tiny larvae clownfish are capable of traveling vast distances—up to 250 miles in search of a new coral home, according to a recent study. Researchers say that this will help the species deal with climate change. The Guardian
The brightly-colored clownfish needs no introduction—the reef fish is one of the most recognizable fish in the world. But aside from being the star of Disney’s “Finding Nemo,” the clownfish has some impressive adaptations and a strange life history.
There are actually 30 species in the clownfish family, but two are the orange-striped fish everyone knows from the big screen. The orange clownfish (Amphiprion percula) and the ocellaris clownfish, or false clownfish, (Amphiprion ocellaris) look nearly identical, but they’re actually two different species. If you get close enough, you can tell them apart by counting the number of dorsal spines on their backs—the orange clownfish has 10 and the ocellaris clownfish has 11.
Guest blogger Jon Bowermaster is a writer and filmmaker. In this post, Jon reports on the dangers of ocean acidification.
Of all the threats to the planet’s ocean, none may be more insidious or have longer-term impact than ocean acidification. It is also the least understood of all the potential harms.
Admittedly it is far easier to visualize plastic afloat on the surface of the Pacific or vast tracts of the Atlantic nearly devoid of fish than a chemical imbalance. But it is the change of acidity that may already be the ocean’s worst enemy.
Try this for a visualization, maybe it will help: 24 million tons of carbon dioxide created by the burning of fossil fuels – or the equivalent of 24 million Volkswagens – are dumped into the world’s ocean every single day.
On top of destroying coral reefs (the equivalent of wiping out rain forests on land) and killing off shellfish beds including mussels and oysters, a new report out of the U.K. suggests that the so-called “evil twin” of global warming is responsible for some fish losing their sense of smell and hearing.
