Fingal's Cave, Scotland.

Fingal's Cave is a sea cave on the uninhabited island of Staffa, in the Inner Hebrides of Scotland, part of a National Nature Reserve.

It is formed entirely from hexagonally jointed basalt columns within a Paleocene lava flow.

In all these cases, cooling on the upper and lower surfaces of the solidified lava resulted in contraction and fracturing, starting in a blocky tetragonal pattern and transitioning to a regular hexagonal fracture pattern with fractures perpendicular to the cooling surfaces.

As cooling continued these cracks gradually extended toward the centre of the flow, forming the long hexagonal columns we see in the wave eroded cross-section today.

Its size and naturally arched roof, and the eerie sounds produced by the echoes of waves, give it the atmosphere of a natural cathedral. The cave's Gaelic name, An Uaimh Bhinn, means "the melodious cave."

It has inspired many artists, writers and composers, including August Strindberg, Felix Mendelssohn and Pink Floyd.

Some anglerfish, like those of the Ceratioid group (Ceratiidae, or sea devils), employ an unusual mating method. Because individuals are presumably locally rare and encounters more so, finding a mate is problematic. When scientists first started capturing ceratioid anglerfish, they noticed that all of the specimens were female. These individuals were a few centimetres in size and almost all of them had what appeared to be parasites attached to them. It turned out that these "parasites" were highly reduced male ceratioids. The presence of multiple males breeding with a single female makes this a good example of polyandry.
