Eight Arms, No Spine

They had more water than usual at the Santa Monica Pier Aquarium, due to a bit of octopus sabotage:

The female California two-spotted octopus swam to the top of her tank, disassembled a valve with her powerful arm, and released at least 200 gallons (757 liters) of seawater into nearby exhibits and offices.

Scientists don't know what to make of it.

Such high jinks are typical of the invertebrates' still unexplained smarts, experts say.

I fear they're underrated
because we're not closely related.
