This is an example of the kind of creatures we are crowd forging with viewers during our world building streams!
A Mass Darter is a skinny, long creature that is a living harpoon about the size of a hawk. This creature flies above and then dive bombs other larger creatures, forcing them to crash land while the Mass Darter eats. These creatures may swarm (like piranha) to attack their prey. They may even ride their prey nearly all the way to the ground.
