Tardigrades are ubiquitous microinvertebrates exhibiting extreme tolerance to various
environmental stressors like low and high temperatures, lack of water, or high radiation …

Tardigrades are microscopic animals found worldwide in aquatic as well as terrestrial
ecosystems. They belong to the invertebrate superclade Ecdysozoa, as do the two major …

Water is essential for life, but anhydrobiotic tardigrades can survive almost complete
dehydration. Anhydrobiosis has been a biological enigma for more than a century with …

The panarthropod head represents a complex body region that has evolved through the
integration and functional specialization of the anterior appendage-bearing segments …

No consensus exists for the homology and terminology of the male genitalia of the
Hexapoda despite over a century of debate. Based on dissections and the literature, genital …

Phylum Tardigrada (water bears), well known for their cryptobiosis, includes small
invertebrates with four paired limbs and is divided into two classes: Eutardigrada and …

We describe Collinsium ciliosum from the early Cambrian Xiaoshiba Lagerstätte in South
China, an armored lobopodian with a remarkable degree of limb differentiation including a …

Abstract Knowledge on neuropeptide receptor systems is integral to understanding animal
physiology. Yet, obtaining general insight into neuropeptide signalling in a clade as …

Tardigrades are microscopic aquatic bilaterians that despite their size have a complex
morphology and anatomy. These minute animals need a surrounding film of water to be …

Tardigrada is an ancient lineage of miniaturized animals. As an outgroup of the well‐studied
Arthropoda and Onychophora, studies of tardigrades hold the potential to reveal important …
