Keeping To A Liquid,

or fluid nature,

 shoals or flocks of hybrid creatures,

 swarm across,

 buildings,

 that can be seen in Sweden, Morocco, Florida, and elsewhere,

 they are the work of Portuguese artist Pantónio, 

many of the pieces seem to be swirling through water or comprised of liquid itself, often taking inspiration from creatures found in the Tagus river that flows through the middle of Portugal,

I know it is a rabbit, but it looks so much like the movement of a fish, You can see more of his work on Facebook, what lovely flowing swarms of creatures to be sure.
