We're taking away creatures' senses. (via hakaimagazine)
an online publication about science and society in coastal ecosystems. Read more stories like this at Dungeness crabs hunt by flicking their chemical-detecting antennae to and fro. Sensing the water—the underwater equivalent of sniffing the air—is a well-trod strategy for homing in on potential prey. But that timeless tactic appears to be at risk, as that climate change–induced ocean acidification seems to cause Dungeness crabs’ antennae to falter.
And it’s not just Dungeness crabs that appear to be in trouble. Acidification threatens to deprive a variety of marine species of crucial chemical cues. Research into this phenomenon is still limited, but as the field develops, the scope of the potential consequences is growing clearer. Just like on land, where animals smell and taste chemicals to glean vital information, many marine creatures use chemical cues to spot food, locate potential mates, or avoid nearby predators. Chemoreception works because each of these cues is a molecule with a distinct chemical structure and physical shape. But because all of these chemicals are floating around in water, they’re susceptible to a range of chemical reactions.
