First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

Acta Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...

AI‐Assisted Morphometric Analysis and Molecular Phylogeny for a Dactylogyrid (Monopisthocotyla) Skin Parasite of an Ornamental Crenuchid Fish From Brazil

Acta Zoologica, EarlyView.
ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.

Absence of a Hectocotylus and Associated Mating Behaviour in the Paintpot Cuttlefish Ascarosepion tullbergi

Acta Zoologica, EarlyView.
ABSTRACT A hectocotylus is a sexually modified arm used by males of some cephalopod species to transfer spermatophores to females. In most cuttlefish (Sepiidae), it corresponds to the left arm IV, in which basal suckers are reduced or absent; this modification is thought to facilitate sperm transfer without premature rupture, which could be caused by ...

Same Same, but Different: A Glossary of Carcino‐Entomology as a Basis for an Improved Communication and for a Modern View of Carcinology Encompassing Entomology

Acta Zoologica, EarlyView.
ABSTRACT One core aspect of science is communication, both among researchers as well as with the public. For successful communication, it is crucial that the terminology used is clear to avoid misunderstandings. Especially when researchers working on different groups of organisms communicate, they often use different terms for similar morphological ...

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

Acta Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...
