Pangolins are rare, secretive, slow-moving, solitary and nocturnal scaly mammals - the world's only! They have a tapered body shape, varying in size from 30-100cm, with males being larger than their female counterparts. Covering their body and tail are sharp, overlapping keratin scales - the same material as human fingernails. Although pangolins share similar characteristics with Xenarthrans (anteaters, armadillos and sloths), they are actually more closely related to to the order Carnivora (cats, dogs, bears, etc.) [1]. They are also insectivorous and it has been estimated that an adult pangolin can consume an excess of 70 million insects per year! ‘Pangolin’ originates from the Malay word ‘penggulung’ which means ‘rolling ball’. As a defensive posture, pangolins curl up into a tight sphere, projecting their sharp-edged scales. There are eight extant species. Four species are native to Asia and include the Chinese Pangolin (Manis pentadactyla), Indian Pangolin (Manis crassicaudata), Malayan Pangolin (Manis javanica) and Palawan Pangolin (Manis culionensis). The other four species are native...

A rare and spooky looking fungus called the Devil’s Fingers (Clathrus archeri) was discovered on Halloween at a Nature reserve near Bristol. The Devil’s Fingers is a saprotrophic fungus (soil-forming mushroom) native to Australia and New Zealand [1]. This organism lives off decaying matter and is part of a family of death reeking funguses known as stinkhorns. The Devil’s Fingers was first recorded in Europe in France, 1914. Presumably, this species was transported to Europe with Australian wool or, alternatively, with military supplies at the beginning of the First World War [2]. Its first recorded presence in Britain was in Cornwall, 1946. This was a surprising identification by an Avon Wildlife Trust conservation team on October 31st as there have only been two known records in this region, both from 1999. Also known as Octopus Fungus, this fungal species sprouts red tentacle-like arms from a partly buried white gelatinous ‘egg’. These arms stand vertically and are initially joined at the tip before unfolding backwards into a star shape. 5-7 (sometimes up...

A new in German study published in the journal, Nature, confirms that some insect species are being pushed to the brink of extinction! Invertebrates make up 97% of the Earth’s animal species [1] and range in size from microscopic mites and almost invisible flies to giant squids with football sized eyes. Invertebrates are the most diverse group of animals and so far around 1.25 million invertebrate species have been described, most of which are insects. Indeed, every day new invertebrate species are being described by morphological and molecular data [4]. The success of insects comes from their ability to reproduce quickly and their adaptability to environmental change. Despite this, more than 40% of insect species are declining and a third are endangered worldwide – with an extinction rate eight time faster than that of birds, mammals and reptiles! New research has found insect and spider populations to be declining rapidly in forests and grasslands across Germany, scientists describe these findings as ‘alarming’ [3]. This...
