Built for sur­vival

It might be sim­ple, but the tardi­grade’s tiny body is the per­fect sur­vival pod

How It Works - - ENVIRONMENT -

Tiny eyes

Tardi­grades sense their en­vi­ron­ment with small, five-cell eye­spots and sen­si­tive fil­a­ments called cirri.

in-built straw

A suck­ing phar­ynx ex­tracts fluid from food and sends it to the sim­ple di­ges­tive sys­tem.

pierc­ing mouth­parts

Sharp struc­tures called stylets in the tubu­lar mouth pierce in­ver­te­brates, plants cells and al­gae dur­ing feed­ing.

Al­ways breath­less

Tardi­grades have no blood or res­pi­ra­tory or­gans. In­stead, gas ex­change oc­curs across the sur­face of the body.

stumpy legs

Three pairs of legs are used for lo­co­mo­tion, while the pair at the back is used to cling to sur­faces.

sin­gle sex or­gan

Males and fe­males each have a sin­gle go­nad with an open­ing through which cells are re­leased for ex­ter­nal fer­til­i­sa­tion.
