Tarantulas have urticating hairs which may cause severe irritation of the skin, respiratory tract and eyes. Inflammation and granulomas (ophthalmia nodosa) can develop in the anterior and posterior segment of the eye presenting as keratoconjunctivitis or uveitis. We present a case of a female patient with an intracorneal tarantula hair and subsequent keratouveitis after contact with a pet tarantula. Because of the unsatisfactory effects of topical steroids surgical removal of the tarantula hair was performed which resulted in remission of the inflammatory signs and recovery of visual acuity.

Aquatic environments are being polluted by microplastics primarily originating from the washing of synthetic textiles. Microfibers (MF), which are microplastics in synthetic fibers, are consistently introduced into the environment with each domestic laundry cycle. To address this issue, we developed a specialized MF capture "barbed filter" (BF) by transforming PET monofilaments of different diameters (0.

The extreme asymmetry of species richness distribution across the tree of life has always intrigued evolutionary biologists. Two competing explanations have been proposed to explain this pattern-the clade age hypothesis and diversification rate variation. While these two scenarios may not be mutually exclusive, to what extent time and diversification rates interact to explain species richness patterns remains understudied.

The tarantula genus Tmesiphantes Simon, 1892 includes 20 valid species distributed in Argentina and Brazil. These spiders are distinguished from other Theraphosinae genera by the presence of an incrassate femur III, more evident in males, urticating hair types III and IV on the abdominal dorsum, few cuspules on the labium (0 to 30), maxillae with a maximum of 200 cuspules and sternum rounded. From recent examination of material from Peru, we discovered specimens that share all the morphological characters of Tmesiphantes, but did not fit with any known species.
