Most fish breathe water with their gills, but a surprising number of can inhale air directly. Even common household pets such as Siamese fighting (betta fish, Betta splendens) at the surface, so they live in tiny bowls without filters or aeration. The Alaskan blackfish (Dallia pectoralis) shares this superpower. A modified esophagus lets them ‘surface breathe’, get oxygen even stagnant and mudd...

A total of 1,426 species of plants had been tested in order to find out a vegetal-derived molluscicide against the vectors of Schistosoma mansoni. Euphorbia splendens is one of the most promising molluscicides. In this article we briefly present the main aspects that have to be considered to use this plant as a molluscicide, which include some agricultural aspects and operational methods for ap...

Mediporus splendens gen. n. and sp. n. is described and illustrated based on specimens from Thailand. In addition, a key to genera of the Evacanthini is provided.

Calopteryx splendens males exhibit a remarkable variation in wing pigmentation both within and between populations. In this study, we examined whether the wingspots of male C. splendens are related to male quality. We measured the nylon implant encapsulation rate for 85 males and found that males with larger wingspots had a faster encapsulation rate, indicating a better immunocompetence. We als...

Viable biocontrol agents for mosquito control are quite rare, therefore improving the efficacy of existing biological agents is an important study. We need to have a better understanding of the predation-risk behavioral responses toward prey. This research examined prey choices by Toxorhynchites splendens by monitoring the behavioral responses of Aedes aegypti, Aedes albopictus, and Anopheles s...
