You can daisychain them, and each LED is individually addressable.
For further information about the internal chip WS2811 you can get the data sheet here.
to drive the LEDs with your Arduino you can use this library:
If they start acting a little flaky you can add a decoupling capacitor.
An 0.1uF ceramic capacitor seems to make it work perfectly every time.
