For such tiny creatures there are numerous dangers from predators in the ocean,

which the small cuttlefish tries to master using various tactics.

It can adapt almost perfectly to its surroundings,

and disappear into the smallest cracks or crevices in the reef.

In keeping with its size, only comparatively small benthic prey is on its menu.
