An arthropod (from Greek arthro-, joint + podos, foot) is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages. Arthropods form the phylum Arthropoda, and include the insects, arachnids, myriapods, and crustaceans. Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Their versatility has enabled them to become the most species-rich members of all ecological guilds in most environments. They have over a million described species, making up more than 80% of all described living animal species, some of which, unlike most animals, are very successful in dry environments.
Arthropods range in size from the microscopic crustacean Stygotantulus up to the Japanese spider crab. Arthropods' primary internal cavity is a hemocoel, which accommodates their internal organs, and through which their haemolymph - analogue of blood - circulates; they have open circulatory systems. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-like", with paired ventral nerve cords running through all segments and forming paired ganglia in each segment. Their heads are formed by fusion of varying numbers of segments, and their brains are formed by fusion of the ganglia of these segments and encircle the esophagus. The respiratory and excretory systems of arthropods vary, depending as much on their environment as on the subphylum to which they belong.
Wikimedia Commons (or simply Commons) is an online repository of free-use images, sound, and other media files. It is a project of the Wikimedia Foundation.
Files from Wikimedia Commons can be used across all Wikimedia projects in all languages, including Wikipedia, Wikibooks, Wikivoyage, Wikispecies, Wikisource, and Wikinews, or downloaded for offsite use. The repository contains over 30 million media files. In July 2013, the number of edits on Commons reached 100,000,000.
The project was proposed by Erik Möller in March 2004 and launched on September 7, 2004. A key motivation behind the setup of a central repository was the desire to reduce duplication of effort across the Wikimedia projects and languages, as the same file had to be uploaded to many different wikis separately before Commons was created.
Several sister projects (e.g. Dutch, Swedish, Danish, Norwegian, Spanish, Basque, Polish, Czech and Slovak Wikipedias) moved all their media content to Commons and stopped allowing local uploading. Some projects, such as the English Wikipedia, have more compliant copyright policy and allow to upload and keep files which are not acceptable at Commons, e.g. fair use images.

The WILD Classroom: Intro to Arthropods!
Dan Babbitt, manager of the Smithsonian’s Insect Zoo, shows why the name of the zoo is a little imprecise. The Insect Zoo is home to all five major groups of arthropods—insects, arachnids, crustaceans, millipedes, and centipedes—all of which Babbitt defines.
The incredible diversity and dominance of arthropods in the ocean can be attributed to their extraordinarily adaptable body plan.
Recommended by Vsauce and Laughing Squid, this song will floor you with incredible images and surprisingly good music production. Got to see this one to believe it... What's an arthropod? Lucas Miller, the "singing zoologist," gives you the low-down in a music video that is hilarious and truly a spectacle! With the help of entomologists (and photographers) John & Kendra Abbott, this video shows you the full spectrum of arthropod splendor. And that kid really sells the cockroach costume, doesn't he?! Lyrics: Do you ever feel like a stinky shoe Just blocked out the sun, and next will step on you? Do you ever feel like a roach motel Was built just for you, you are its clientele? Do you ever feel like you give folks the creeps? Six year olds all scream and grown men shut their eyes and we...

Do Amazonian houses have more bugs that houses in the US? That is one of the core questions we've come to answer. Michelle, Misha, Keith, Haley and I are all here in the hot, sweaty jungles of Peru looking in people's homes. What we found was really surprising. The other bug videos can be seen here: https://www.youtube.com/playlist?list=PL5BRja99NkXna1qy-r4S-eJ-Tojcb073m Also, don't forget to check out Anna and Tom's videos: Anna's GROSS SCIENCE Spider Vid:https://youtu.be/5i9X8h17VNM Tom's Bug Rap: http://bit.ly/1Lhdq4p Subscribe to Untamed Science: https://www.youtube.com/channel/UCFAbxaVl6PJMwbMMXX9ZcNw Spread the word and follow us on: FB: https://www.facebook.com/pages/Untamed-Science/169220075768 Twitter: http://www.twitter.com/untamedscience Don’t forget to subscribe to thi...

Isn't this enough to feed your lust does the blood not
satisfy your tongue it used to kill the cravings it used to soothe the beast
I used to chant the
suicide mantra and it was all that I could hear and you waited for the endge
so you could be
the vulture so you could feast away but now you grow impatient and the hymn
is not enough
you're begging for the symphony and calling for the maestro to strike up the
band and cut my
feeble throat isn't this enough isn't this your ride playing with the
handgun painting with my
blood and constructing ugly portraits to make me burn the brushes
