Open-access.   (one thing the popular article appears to get wrong: that
there are just "dozens" of snapping shrimp species.  Original article says
that over 80% of at least 600 species of Alpheids snap.  Further, many,
maybe most, species are small, many tiny ones live in reef rubble and cause
the "frying bacon" sound on reefs.)

Original article:

Parallel saltational evolution of ultrafast movements in snapping shrimp
claws.
