| Billfishes are well known for their distinctive elongated rostra, i.e. bills. The functional significance of billfish rostra has been frequently discussed and the recent discovery of an oil gland (glandula oleofera) at the base of the rostrum in swordfish, Xiphias gladius, has added an interesting facet to this discussion regarding the potential co-evolution of gland and rostra. Here, we investigated the oil gland and oil pores (through which the oil is brought to the skin surface) of four billfish species – swordfish, Atlantic blue marlin (Makaira nigricans), Indo-Pacific sailfish (Istiophorus platypterus) and striped marlin (Kajikia audax) – and provide detailed evidence for the presence of an oil gland in the last three. All four species had a high... |

| Abstract Since early 2000 years, the knowledge about the taxonomy of Aloninae (Cladocera: Chydoridae) has been in rapid progress. For this reason, the most of Brazilian fauna was affected concerning nomenclature, besides an increase in the number of known genera and species. Thus, in this study, we bring an updated species list of Aloninae in Brazil, as well as identification keys based in current nomenclature and morphological standards. Our finding pointed to the occurrence of 46 valid species, belonging to 21 genera and three groups of Alona sensu lato. Two of these genera are endemic to Brazil. So far, South-East Asia and Brazil have the most well-studied Aloninae fauna in the entire planet. |
