Snails and CO2



Hope you are seated for this because it could ruin your day. “Effects of climate change could hinder a sea snail’s ability to leap away from predators on one foot”, Queensland researchers say. Did I read that right?

The study, reported in the Fjii Times, shows the Conch snail, found in sandy areas off coral reefs, finds it difficult to quickly jump out of reach of prey when exposed to higher levels of carbon dioxide.

Dr Sue-Ann Watson of James Cook University’s Centre of Excellence, who is a self-confessed global warmist, says the chemical CO2 disrupts the snail's neurotransmitter receptor, causing it to have a delayed response.

“The snail either stops jumping or takes longer to jump when exposed to the levels of carbon dioxide projected for the end of this century”, the marine biologist said. (Have you fallen off your chair yet?)

"This might leave the three to four centimetre Conch snail more vulnerable to the dart of the slow-moving, predatory Cone shell.

"Snails normally move slowly and crawl around on their one big foot," Ms Watson said.

So, the level of carbon dioxide in eighty six years’ time (projected of course by our global warming friends) might affect a sea snail!

Bloody hell, that makes the Syrian crisis look like a picnic.

But every dark cloud has a silver lining... in eighty six years’ time it seems the deprived, slow-moving Cone shell will find it much easier to get a feed. Phew, global warming isn’t all doom and gloom after all.

I phone-messaged Sue-Ann to ask if the dung beetle was getting enough tucker at her Centre of Excellence, but I have yet to receive a reply.
