Pauropods are small, pale, centipede-like arthropods. They form the order Pauropodina, belonging to the monotypic class Pauropoda. About 500 species in four families are found worldwide, living in soil and leaf mould. They look rather like centipedes, but are probably the sister group to millipedes. The name is derived from the Greek roots pauro "few" and podo "foot".
Pauropods are soft, cylindrical animals with bodies 0.5 to 2 millimetres (0.02 to 0.08 in) long. The first instar has three pairs of legs, but that number increases with each moult so that adult species may have nine to eleven pairs of legs. They have neither eyes nor hearts. The body segments have ventral tracheal/spiracular pouches forming apodemes similar to those in millipedes and Symphyla, although the trachea usually connected to these structures are absent in most species. The antennae are branching, which is distinctive for the group.
Pauropods live in the soil, usually at densities of less than 100 per square metre (9/sq ft).
HyperText Markup Language, commonly referred to as HTML, is the standard markup language used to create web pages. Along with CSS, and JavaScript, HTML is a cornerstone technology, used by most websites to create visually engaging web pages, user interfaces for web applications, and user interfaces for many mobile applications.Web browsers can read HTML files and render them into visible or audible web pages. HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language.
HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items.
The language is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>
). Browsers do not display the HTML tags and scripts, but use them to interpret the content of the page.
This is a pauropod, an obscure proto-millipede from the UK. This was around 1.5mm big. They're unique as they have strange, bifurcated antennae, a very ancient family. They live, mostly un-noticed, in the deep leaf litter and upper soil layers.

This is a video of Trachypauropus brittanicus, a sclerotised pauropod from the UK. This is the first video of a live specimen in habitus. At around 1mm big, it was only discovered in 1982. It lives in deep leaf litter and the upper soil layers. This was shot on an iPhone 5s.
Tras un siglo de debate acerca de si los miriápodos constituyen un grupo natural, éste ha sido resuelto decisivamente en favor de la monofilia del clado gracias a los datos moleculares. Sin embargo, las interrelaciones de los cuatros grupos principales de Myriapoda - Symphyla, Pauropoda, Diplopoda y Chilopoda - sigue generando controversia. La teoría clásica morfológica sostiene que los paurópodos y diplópodos son grupos hermanos, con los sínfilos como pariente más cercanos. Por otra parte, algunos datos moleculares sugieren que sínfilos y paurópodos se unen en un clado, una nueva hipótesis sustentada por el análisis de múltiples genes. Los análisis filogenéticos basados en datos moleculares y/o morfológicos sostienen la hipótesis de que los miriápodos son el grupo hermano de Pancrustac...

Myriapoda is a subphylum of arthropods containing millipedes, centipedes, and others. The group contains over 13,000 species, all of which are terrestrial. Although their name suggests they have myriad legs, myriapods range from having over 750 legs to having fewer than ten legs. The fossil record of myriapods reaches back into the late Silurian, although molecular evidence suggests a diversification in the Cambrian Period, and Cambrian fossils exist which resemble myriapods. The oldest unequivocal myriapod fossil is of the millipede Pneumodesmus newmani, from the late Silurian. P. newmani is also important as the earliest known terrestrial animal. The phylogenetic classification of myriapods is still debated. This video is targeted to blind users. Attribution: Article text available un...
We're going out on a limb
Our people are about to disown us now
Incrementally cahnge mentality
Speak of values miss the irony
What you once shunned
Is now what you seek
Three hundred sixty
And never miss a beat
Your people call my people
What's this? i'm skeptical
Success come knockin'
And we're dabblin'
See the circles that we travel in
Access babylon, access babylon
All access, yeah, but not quite
Your cast goes left but not allowed right
Force field limbo caught in mid strata
Funds evaporate so called friends scatter
Your people call my people
What's this? i'm skeptical
Success come knockin'
