A new giant species of placented worm and the mechanism by which onychophorans weave their nets (Onychophora: Peripatidae)
(Universidad de Costa Rica, 2010)Onychophorans, or velvet worms, are poorly known and rare animals. Here we report the discovery of a new species that is also the largest onychophoran found so far, a 22cm long female from the Caribbean coastal forest of ... -
A proposed solution to the species problem in velvet worm conservation (Onychophora)
(Universidad Estatal a Distancia, 2018)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 ... -

Unexplored Character Diversity in Onychophora (Velvet Worms): A Comparative Study of Three Peripatid Species
(Sars International Centre for Marine Molecular Biology, Norway, 2012-12-17)Low character variation among onychophoran species has been an obstacle for taxonomic and phylogenetic studies in the past, however we have identified a number of new and informative characters using morphological, molecular, ... -
Variación estacional y características fisicoquímicas e hidrológicas que influyen en los macroinvertebrados acuáticos, en un río tropical
(Universidad de Costa Rica, Costa Rica, 2020-10-22)Introduction: The distribution of aquatic macroinvertebrates in rivers may be determined by the type of substrate, the shape of the river channel, the hydrological regime, and interactions with biotic and abiotic factors. ...
