Vampyrella crystallifera sp. nov., an Amoeba That Dissolves Entire Algal Cells at a Remarkable Speed
Ecology and Evolution, Volume 15, Issue 3, March 2025.The new vampyrellid amoeba Vampyrella crystallifera inhabits wet Sphagnum plants in temperate moorlands. Unlike its congeners, it engulfs entire algal cells and breaks them down at a fascinating speed. This represents a feeding habit that was unexpected for the genus Vampyrella and showcases the exceptional diversity of predator–prey interactions found

On the Maxillofacial Development of Mice, Mus musculus
Journal of Morphology, Volume 286, Issue 3, March 2025.This study focused on the craniofacial development of the mouse (Mus musculus), particularly the maxillofacial region. Using three‐dimensional reconstructions of histological sections combined with whole‐mount staining, we provided a detailed description of skeletal, neural, and vascular formation from the pharyngula (9.0 dpc) to late fetal stages (18 ...

A Silurian placoderm with osteichthyan-like marginal jaw bones
Nature, 2013 The gnathostome (jawed vertebrate) crown group comprises two extant clades with contrasting character complements. Notably, Chondrichthyes (cartilaginous fish) lack the large dermal bones that characterize Osteichthyes (bony fish and tetrapods). The polarities of these differences, and the morphology of the last common ancestor of crown gnathostomes ...

Precaudal Vertebrae in the Postcranial Region of Moray Eels Form Ventral Processes
Journal of Morphology, Volume 285, Issue 10, October 2024.The precaudal vertebrae in the postcranial region of moray eels form ventral processes with blood vessels. ABSTRACT Fish vertebrae are primarily morphologically classified into precaudal vertebrae jointed to the ribs and caudal vertebrae with hemal spines, through which the caudal artery and veins pass.

The Paleozoic and Mesozoic vertebrate record of Venezuela: An overview, summary of previous discoveries and report of a mosasaur from the La Luna Formation (Cretaceous) [PDF]
, 2018 Most reports of Paleozoic and Mesozoic vertebrates from Venezuela are anecdotical, with few detailed descriptions of mostly ‘fish' groups. Synapsids (e.g., mammals) are totally unknown, and dinosaurs are only reported from the La Quinta Formation.

Darwin, Haeckel, and the “Mikluskan gas organ theory”
Developmental Dynamics, Volume 253, Issue 4, Page 370-389, April 2024.Abstract A previously unknown reference to the Russian ethnologist, biologist, and traveler Nikolai N. Miklucho‐Maclay (1846–1888) was discovered in correspondence between Charles Darwin (1809–1882) and Ernst Haeckel (1834–1919). This reference has remained unknown to science, even to Miklucho‐Maclay's biographers, probably because Darwin used the ...
