Just an anemonic monday.

Anemonies have a story

Monday, and this anemone is ready to party with an eye catching red outfit, an insect magnet. Petals open up fully over a week during which time they develop their red colour. Bees dont see red, but yellows and orange are ok. The light receptors in our eyes respond to red, blue and green wavelengths. The light receptors in bee eyes respond to green, blue and higher energy ultraviolet wavelengths.

Monday and this anemone is ready to party. The deep blue mound in the centre is a bee magnet.

Human retinas are packed with banks of cone-shaped light receptors. Three different types are activated by long, medium or short light wavelengths. (sometimes referred to as red, green and blue cones)

We can distinguish a huge range of colours with three types of cone cells, how is this possible? Luckily each cone is sensitive to a range of wavelengths. Activated cone cells send electronic signals through the optic nerve to the brain for processing. The relative input from each type of cone determines what we see as colour. The brain is programmed when we learn our colours in childhood.

Bees use the same trick with three different cone types. The light they react to is shifted to shorter wavelengths, green, blue and ultraviolet light. (sensitivity shifted to shorter wavelengths.)

It takes about a week for the petals to develop their colour. Closed overnight the bud springs open in the early dawn light.

A bit messy with pollen dust spilling all over the show. Petals are almost fully developed

Black  shiny anthers split open as if ripped apart with a tiny razor. Millions of tiny pollen grains each a discrete male organism are good to go looking for eggs to fertilise. Green anther heads have not yet reached maturity.
