@WarnerCrocker No wonder they’re so sticky! This is very cool!!
@farah @WarnerCrocker I kinda wish I could extrude something as cool as this out my butt. =D

@WarnerCrocker

“… Australian netcaster spider holds a specialised, sticky net between its four front legs. When an unsuspecting insect approaches, the spider rapidly expands its net and casts it over the prey, a manoeuvre that demands dramatic extensibility from the supporting lines at the sides of the sticky net. These threads are composed of an elastomeric core encased in a sheath of harder fibres of varying sizes; the result is a structure that is both strong and stretchy.”

@WarnerCrocker I was like, amazing, what system did you use to program... oh... even more amazing.

@bit101 @WarnerCrocker genetic optimization run for a very, very long time.

Must have also won the prize for most expensive rig: “captured using a Zeiss GeminiSEM 360 field-emission scanning electron microscope under high vacuum and after coating of Au-Pd.”

@WarnerCrocker Todd McFarlane was right all along!
His Spiderman spaghetti webbings weren't that far off!
@WarnerCrocker #Alt4You Greyscale picture of a microscopic enhancement of spider thread running horizontally. The thread is two stranded, with a smooth tube as the base, atop of which is attached multi-layered ribbons swirling around the tubes. The ribbons resemble the wavy edges of a clam shell.

@WarnerCrocker

Looks like a sticky spiral wicket.
