Mary's Monday Metazoan: Denizens of the icy deeps

You know those deep icy fields of methane hydrates Japan wants to tap for natural gas? (One of the worst ideas ever, by the way.) They're inhabited, by polychaetes like Hesiocaeca methanicola.

The orange gas hydrate is home to Hesiocaeca methanicola, a newly discovered species of marine worm found in the Gulf of Mexico in 1997. This lobe of hydrate was exposed on the seafloor. The Deep East Expedition will investigate the life above and in a shallow bed on the Blake Ridge where other…
Once upon a time, before I descended into parenthood and dull stability, I was out with a group of friends who had, let's just say, been drinking quite a bit. One of the young men in this group proposed to two others that they do something that was, to put it bluntly, totally moronic and likely to…

Huh. Wonder what kind of life there is on Titan then?

Polychaetes breathe oxygen. On Titan there's no oxygen.

Hey David, it doesn't matter if there's no oxygen. Those "life forms" (if their are any), don't need oxygen. They could easily breath another gas.

PZ did you read the paragraph where Lavelle compares Methane to Carbon Dioxide? It echoes my immediate reaction to hearing that methane clathrates were targeted for fuel extraction... "better to release it as CO2 than CH4." I don't doubt you knew this but it may explain why Lavelle's tone is less critical than you expect.

Her companion piece goes into detail as to why: more methane than ever is seeping into the atmosphere.

@ Bughunter, Myers barely responds to comments on the scienceblogs version.

They could easily breath another gas.

Or indeed a solid dissolved in liquid methane. But what could that be? Are there methane-soluble sulfides?

Oops, forgot:

“better to release it as CO2 than CH4.”

Into the atmosphere, yes. Into the sea, where it gets from the atmosphere, no. The oceans are already acidifying to a scary degree.
