Suffolk Wildlife Trust (SWT) describes itself as the county's "nature charity – the only organisation dedicated wholly to safeguarding Suffolk's wildlife and countryside." It was founded in 1961, and is one of 46 wildlife trusts covering Great Britain and Northern Ireland. The trust manages 3,120 hectares (7,700 acres) of land in 60 nature reserves, most of which are open to the public. The whole or part of nine SWT reserves are Ramsar internationally important wetland sites, thirty-one are Sites of Special Scientific Interest, four are national nature reserves, and ten are Special Protection Areas. One SWT reserve is in Dedham Vale, which is an Area of Outstanding Natural Beauty (AONB), and seven are in another AONB, Suffolk Coast and Heaths. (Full list...)

Thecacera pennigera

Thecacera pennigera, also known as the winged thecacera, is a species of sea slug in the family Polyceridae. It has a cosmopolitan distribution, being found in temperate waters on either side of the North Atlantic Ocean, in the Mediterranean Sea, around South and West Africa, Brazil, Japan, Korea, Pakistan and more recently in Australia and New Zealand. There is a significant difference in colouring between Atlantic populations and Pacific specimens, however. Thecacera pennigera has a typical adult length between 15 millimetres (0.6 in) and 30 millimetres (1.2 in), featuring a short, wide head with two lateral flaps and two sheathed olfactory organs called rhinophores. The body is wedge shaped, being wide at the front and ending in a slender foot with a lateral keel on either side. The general colour of the body is translucent white and the upper side is covered with orange splotches and small black spots. Like other sea slugs, T. pennigera is a hermaphrodite with internal fertilisation and a mating mechanism whereby pairs of animals exchange packets of sperm. This T. pennigera was photographed in the Mar Piccolo of Taranto, Italy.
