The day shift has logged off, and the night shift has gone to work. It's mean and moody¹, and the animals here mean business.

 

Just as in human cities, there's a new cast of characters after dark. 

Octopus² emerge from their holes to stalk their prey³.

A tiny sole improves his  chances of survival by mimicking⁴ a toxic⁵ flatworm. Some of the strangest nocturnal creatures are relatives of the starfish, like this feather-mouthed sea cucumber, sifting⁶ food from the sand.

 

Another is the basket star. It comes alive at night, throwing out thousands of arms to filter food from the plankton-rich current.

These animals can live for a very long time, up to 35 years. And there's records of these guys being seen night after night, in the same place for over 15 years.
