The Last of Us zombie fungus has nothing on the brain-eating, sex-changing, Sacculina barnacle.

The Last of Us zombie fungus has nothing on the brain-eating, sex-changing, Sacculina barnacle.
Science

In the Last of Us, the most gruesome live-action adaptation of a video game about people being turned into fungus since 1993’s Super Mario Bros, a mutated species of Cordyceps destroys society by converting humans into mindless, sporulating mushroom people.

Cordyceps, a fungus that most commonly parasitizes ants, is real. It really does hijack its host’s nervous system, alter its behavior, and turn it into a spore-producing zombie. The outcome is strangely beautiful.

Though the current darling of gritty, realistic, science-based zombie fiction, Cordyceps is such a lightweight in the world of brain-breaking parasites that tech bros brew it into their adaptogenic coffee.

If you want to meet a truly unsettling zombie-making parasite, allow me to introduce you to Sacculina.

Sacculina is a genus of barnacle that parasitizes crabs. While most parasitic barnacles are perfectly happy growing on the carapace of a crab, Sacculina takes this partnership to the extreme.

Female Sacculina larvae drift through the ocean, until they encounter a crab. The larva then settles on the crab and searches for a joint in the crab’s carapace. Once it finds a gap in the arthropod’s armor, it transforms into a kentrogon, a specialized phase of the barnacle life cycle that possess a stylet–an organic syringe-like structure–which allows Sacculina to inject itself into the crab, and not much else. At this point, the hard shell attached to the crab’s carapace falls off and the barnacle continues to grown within its host.

It gets so much weirder from here.

Flotsam (what we’re obsessed with right now)

  • Investing in indigenous communities is most efficient way to protect forests, report finds. This should surprise no one but it often does.
  • Explore the deep waters around Kiribati with OpenExplorer!

The Levee (A featured project that emerged from Oceandotcomm)

  • Virtual Reality Preserves Disappearing Land: Coastal communities are capturing their cultures and landscapes in virtual reality before sea level rise steals them for good.

  • The Eruption at Kilauea on Hawai’i’s Big Island is truly spectacular, however hundreds of people are displaced from their homes. The mayor has directed those interested in giving donations to contact the Salvation Army at +1 (808) 756-0306.

I’ve been away for 2 weeks, so it’s a super-massive edition of the Monday Morning Salvage!

Fog Horn (A Call to Action)

  • There’s still an unimaginable amount of work to do in Dominica and across the Caribbean. Support the Rebuild Dominica Hurricane Relief fund or any of the other funds from our list: How to help our island colleagues in the wake of total devastation.

Flotsam (what we’re obsessed with right now)

  • This is such a cool story: A Trail of Rocks Traces Historical Steamship Routes. We can track old steamship routes from rocks scraped out of the furnaces and tossed overboard.
  • Former Papua New Guinea Attorney General attacks deep sea mining project. They always pick pictures for these articles that don’t show how much life is right around the vents.

  • Whose ecological footprint is bigger: Medics, economists, or environmentalists? Spoilers: conservationists still have an impact, but they sure ain’t number 1.

Jetsam (what we’re enjoying from around the web)

  • There’s a fresh oil spill in the Gulf of Mexico, and it’s pretty darn huge:
    • Coast Guard Responding to 300,000 Gallon Crude Oil Spill in Gulf of Mexico.
    • Gulf of Mexico Oil Spill May Be Biggest Since 2010.
    • New Estimate Doubles the Size of Last Week’s Oil Spill in the Gulf of Mexico.
  • Some fun from Deep Sea News: When real-life marine biologist and mom goes to sea, she takes the octonauts with her.

  • This is fine: Report on U.S. Marine Sanctuary Oil Drilling Sent to White House, Not Released to Public. This is totally fine: Trump Administration Proposes Largest Oil and Gas Lease Sale in U.S. History.
  • Alaska’s Oyster Farmers Are Filling an Acidification-Driven Void. The state’s oyster farming industry is gaining ground as growers elsewhere struggle. From Hakai Magazine, which is great.
  • Nature is one of the most under-appreciated tools for reigning in carbon. From Anthropocene, which is fast becoming my favorite environmental print magazine. Sorry, Orion.
  • Thousands of penguin chicks starve in Antarctica.

Hey, Andrew, how about you give us at least *some* good news today? Ok, fine.
