Velvet worms, also known as peripatus or onychophorans, are a phylum of evolutionary importance that has survived all mass extinctions since the Cambrian period. They capture prey with an adhesive net that is formed in a fraction of a second. The first naturalist to formally describe them was Lansdo...

Introduction: Charismatic species, like the panda, play an important role in conservation, and velvet worms arguably are charismatic worms. Thanks to their extraordinary hunting mechanism, they have inspired from a female metal band in Japan, to origami worms in Russia and video game monsters in the...
Onychophorans or velvet worm are the only phylum without extant marine species and the only invertebrates with a true placenta, but most species are rare and thus more likely to become extinct. A key obstacle for their conservation is the time and work needed to describe species with the high standa...
Onychophoran worms are considered "living fossils" because their basic body structure has changed little in 500 million years. Only two species have been properly recorded from Mexico: Macroperipatus perrieri from Veracruz, and Oroperipatus eisenii from Nayarit. Here we report an undescribed species...
Velvet worms are ancient predators with Cambrian origins that occasionally prey on Ctenid spiders. Here we report the opposite case: wolf spiders (Ctenus spp.) feeding on Epiperipatus spp. in Colombia and Costa Rica. Apparently the worms could not expel their defensive adhesive, and the efficacy of...
C'est au Brésil que l'on trouve le péripatus acacioi, sorte de fossile vivant invertébré de la famille des Onychophores. Les principaux aspects de sa biologie sont évoqués : habitat, morphologie, locomotion, jet de glu, ingestion d'aliment, exuviation et parturition. Vues réelles, macrocinématograph...
