Broadclub cuttlefish

Male broadclub cuttlefish (Sepia latimanus) displaying threat colouration to another male (not seen). The bands of black and white are used to intimidate other males during the breeding season. Cuttlefish can rapidly change the colour of their skin by dilating or contracting pigment cells called chromatophores. This cuttlefish preys largely on crustaceans, which it catches with a quick strike with its two tentacles (not seen). These are usually kept hidden amongst its eight arms, as here. This cuttlefish is found in the tropical Indo-Pacific region. It may reach a length of around 45 centimetres. Photographed off Indonesia

View of undersurface of brain with meningitis

Meningitis. View of the underside of a human brain affected by a meningitis infection. The underside of the brain stem is seen (at lower centre). Behind this is the cerebellum, part of the hind brain with the rear-end of the cerebrum visible behind. Meningitis is an inflammation of the meninges, the membranes that cover and protect the brain and the vertebral tract. This is seen here as a creamy discolouration at upper centre. Meningitis is caused by either bacterial or viral infection. Viral meningitis is mild and requires almost no treatment, whereas bacterial meningitis is very dangerous and is usually treated with antibiotics
