Nature's 'Hidden World' exposed
Image: Polarised light microscopy of sea cucumber skin.
Stunning microscopy images have been shortlisted in this year's UK Royal Society of Biology photography competition themed The Hidden World.
Providing microscopic insights into frogspawn development, Amy Bateman from Cumbria has used macrophotography and lighting effects to capture the entire development from spawn to froglet in striking detail.

Meanwhile, Chris Carter from Cornwall reveals a line of antheridia on a male branch of a stonewort algae, 'Chara fragifera'; each sphere has a closely-knit set of 'shield cells', outlined in black.

James Patterson from London, framed his follicle image with the circular field of view of the microscope ocular lens to create the illusion of a 'glowing world'.
Revealing the invisible
Steve Lowry from Londonderry used polarised light microscopy to image the skin of a sea cucumber, Synapta, showing paired spicules, referred to as 'plates and anchors'.

Both the skin and 'hooks and anchors' are transparent, only becoming visible when viewed using polarised light.
Young photographer of the Year contender, Alannah Harding from North Shields, also captured a stunning image of the heart of a mouse embryo, perfectly formed and surrounded by other organs.
