Vertebrate bone is composed of three main cell types, the most prominent of which are the osteocytes. These cells are thought to play a fundamental role in bone physiology, however they are entirely absent in most extant species of teleosts, a group that comprises...

We report a nocturnal insect swarm observed aboard the oceanographic ship Cruzeiro do Sul of the Brazilian Navy, while conducting a survey of the Montague guyot (seamount), 389 km distant from the nearest land in the South Atlantic. The insects came from open sea...

White rhinoceroses (Ceratotherium simum) are odd-toed ungulates that belong to the group Perissodactyla and are second only to elephants in terms of large body mass amongst extant tetrapods, making them fascinating studies for how large land animals support and...

The presence of dark pigment spots associated with primary tentacles (or structures derived from them, i.e., rhopalioids) in Staurozoa was recently overlooked in a study on the evolution of cnidarian eyes (defined as a “region made of photoreceptor cells adjacent...

Much genomic-scale, especially transcriptomic, data on spider phylogeny has accumulated in the last few years. These data have recently been used to investigate the diverse architectures and the origin of spider webs, concluding that the ancestral spider spun no...

In birds, observed adult sex ratios often are biased towards males. This bias could arise due to differences between sexes in dispersal or in detectability / catchability, but a preferred explanation has been sex differences in survival. However, most studies investigated...
