Birdeaters and mouse catchers: spiders preying on vertebrates

Image
The darkest of nights: midnight in the Brazilian rainforest. At ground level, the jungle is dusky even during the day, when sunlight barely peers through the dense canopy; after sunset, though, it is pitch black. A rustle in the leaves; a predator on the prowl. Perfectly equipped for night hunting, he navigates the inky darkness with ease. The three-striped opossum may only be as big as a mouse, but he is nonetheless a bug's worst nightmare. As this tiny terror tirelessly patrols the forest floor, his teeth make short work of any arthropod he encounters.  Coming down from a tree root, our little hunter freezes.

Spider Tales 5: Tarantula and tarantella

Image
Tarantula. A famous word for a famous animal. Everyone knows what a tarantula is: it's a massive, impressive, hairy spider.  What typically comes to mind when one thinks "tarantula" is a large Theraphosid spider, such as this  Lasiodora parahybana Nowadays, the spiders colloquially known as "tarantulas" are species in the family Theraphosidae, which is the most diverse (with over 1100 described species ) and the most famous family of the infra-order Mygalomorphae . The smallest Theraphosidae species are about 10 mm long, which is not small by spider standards, and most of them are large to very large. The largest representatives of this family, species in the genus Theraphosa , are the largest and heaviest spiders on Earth, which can reach up to 12 cm in body length and 170g in body mass. Besides their often impressive size, many Theraphosidae sport beautiful colours and patterns, and many New World taxa, such as species in the genera Tliltocatl , Brachypelma , ...
