What are the chelicerates?

Chelicerates, also called podphyl Chelicerata, are the main subfyl of phylum arthropod, aka arthropod, the largest phylum in the Kingdom of animals, with more than a million species recognized by science. Chelicerata includes somewhere between 10% and 30% of all kinds of arthropods: mainly because mites are chelerates and the total estimated number of mites are huge, in hundreds of thousands, perhaps even more than a million.

Chelicerates are named on their Chelicerae, it is named on the jaw that is in a document that is named in a deed of document, which is in a document that is stated in the document. Arthodod subphyla, such as hexapoda (which includes insects). There are five main classes of chelerates: arachnid (spiders, scorpions, mites, etc.), xiphosura (horseshoe crabs), Eupterida (Sea Scorpions), Chammataspidide (Chasmataspidy) and Pycnogonide (Sea Spiders). Of these, Eurpterida and chasmataspidis are extinct and xiphosura, the crab horseshoe - considered “life -fossible" - consists of only four species.

The largest and most successful cheelicerates are by far arachnid. When you hear the word "Arachnid", spiders immediately jump to mind and spiders are truly the most numerous arachnid if only the described species are calculated. About 40,000 spiders were identified, out of a total of 110,000 Arachnids known to science. However, it is likely that the next group of Arachnid - ticks of mites - are actually the most numerous, but due to their small size they must still be adequately classified. Different types of mites may have jEN little external differences, which requires a comparison between DNA sequences to verify different species. This massive project has just begun.

other groups Arachnid include cave spiders (not in fact not spiders), Harvestmen (Daddy long-legs), whip scorpions, scorpions, solifugae and small (<5 cm) pseudoscorpions, schizomids, schizomids and three extinced records.
