Amyciaea
''Amyciaea'' is a genus of ant mimicking crab spiders that was first described by Eugène Louis Simon in 1885. They mimic weaver ants, their preferred prey. Description Spiders in this genus are generally around 5mm in length. They don't have the typical leg position or strong distinction between fore and hind legs typical of thomisids, instead holding the front two legs in the air to mimic antennae. The abdomen bears two dark spots which resemble the compound eyes of Weaver ants. Despite the "antennae" and "eyes" being on opposite sides of the body, the camouflage is effective enough to fool surrounding animals. Behaviour Spiders in this genus live and build their nests in foliage, and on the twigs of trees and bushes. They hang by a silken thread at a safe distance from the ant path to avoid accidental interactions, and feed on the ants by biting their head, instantly paralysing them. The males of this genus exhibit bridging behaviour when searching for a mate; similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Thomisidae Species
The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders. Description Members of this family of spiders do not spin webs, and are ambush predators. The two front legs are usually longer and more robust than the rest of the legs. The back two legs are smaller, and are usually covered in a series of strong spines. They have dull colorations such as brown, grey, or very bright green, pink, white or yellow. They gain their name from the shape of their body, and they usually move sideways or backwards. These spiders are quite easy to identify and can very rarely be confused with Sparassidae family, though the crab spiders are usually smaller. Etymology Spiders in this family are called "crab spiders" due to their resemblance to crab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spiders Of Africa
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Compound Eye
A compound eye is a visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color. The image perceived by this arthropod eye is a combination of inputs from the numerous ommatidia, which are oriented to point in slightly different directions. Compared with single-aperture eyes, compound eyes have poor image resolution; however, they possess a very large view angle and the ability to detect fast movement and, in some cases, the polarization of light. Because a compound eye is made up of a collection of ommatidia, each with its own lens, light will enter each ommatidium instead of using a single entrance point. The individual light receptors behind each lens are then turned on and off due to a series of changes in the light intensity during movement or when an object in moving, creating a flic ...

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

Octavius Pickard-Cambridge
Octavius Pickard-Cambridge Fellow of the Royal Society, FRS (3 November 1828 – 9 March 1917) was an England, English clergyman and zoologist. He was a keen arachnologist who described and named more than 900 species of spider. Life and work Pickard-Cambridge was born in Bloxworth rectory, Dorset, the fifth son of Rev. George Pickard, rector and squire of Bloxworth: the family changed its name to Pickard-Cambridge in 1848 after receiving the property left behind by a relative, Charles Owen Cambridge, of Whitminster House in Gloucestershire. Octavius was tutored at home by the poet William Barnes, after failing to receive admission to Winchester College. He also learned to play the violin from Sidney Smith. He then studied law in London before theology at the Durham University, University of Durham. He was very active and made many friends in this period. He served as steward at steeplechases and presided over the college choral society. In 1857 he presented the Pickard-Camb ...
