Glass House* (Undersea Version)

A

In deep ocean water the glass sponge Euplectella, or Venus flower basket, creates a tubelike skeleton (above and below) up to a foot long, with seven hierarchical structural levels, out of glass (silica), calcium carbonate, and calcium phosphate.

John D. Currey, a biologist at the University of York in England, analyzed the structure and found "a skeleton of extraordinary structural and mechanical refinement," noted a story which appeared in the New York Times.

Back in 2005 this exotic creature made the big time, appearing on the cover of the July 8 issue of Science magazine to highlight the research discussed by Currey.

a scanning electron micrograph of an etched sample of the mineral skeleton showed the laminated silica cement holding the glassy crossing fibers in place.

*Acolytes of Philip Johnson will appreciate that this natural wonder appeared many aeons before the architect's iconic 1948-49 Glass House.

Wow!
Nature's own 3D printing, with an elaborate set of materials.
