A new tube: Worms in the Spinyhead coral reef game

A Christmas tree worm larva settles on live coral and builds a limy tube that the coral grows around. Long after the worm is gone, its tube becomes a blenny’s home.

Where to see it in the game: Only after worms have died, and only now and then.

Spinyhead is a free game you play in your browser: you are a spinyhead blenny, a fish about 3 cm long living in a worm hole on a Caribbean coral head. Feed, fight for a better hole, court, raise eggs and dodge predators, while everything around you behaves the way field biologists have seen it behave. Most behaviors in the game come from published field studies; the rest are borrowed from other reefs or extrapolated, and this page says which. There are 82 on these pages, and more in the game’s field notebook waiting to be found.
