自 1920 年以来定期出版，ACTA ZOOLOGICA 一直保持其作为动物组织、发育、结构和功能领域的世界领先期刊之一的地位。每期发表全球动物学家和生理学家感兴趣的原创研究，在动物结构（从细胞到有机体水平）和发育，重点是功能、比较和系统发育方面。偶尔也会发表评论文章和书评。

Since its inception in 1920, Acta Zoologica has been published regularly and has maintained its status as one of the world's leading journals in the fields of animal organization, development, structure, and function. Each issue features original research of interest to zoologists and physiologists worldwide, focusing on animal structure (from cellular to organismal levels) and development, with an emphasis on functional, comparative, and phylogenetic aspects. Occasionally, the journal also publishes commentary articles and book reviews.

Abstract Bangasternus planifrons (Brullé, 1832) specimens collected from Ankara‐Bala were studied. The paper presents a scanning electron microscopic examination of ultrastructural features of aedeagus and spermatheca of Bangasternus planifrons (Brullé, 1832) ( Coleoptera: Curculionidae: Rhinocyllini ) from Türkiye for the first time. The fact that Bangasternus is a genus with three species in Türkiye makes the study more important. Accordingly, detailed investigation of aedeagus and spermatheca is very important to obtain new diagnostic characteristics in Bangasternus . The parts which include systematic characters such as spermatheca, genital spicule, sternite eight and coxite figures were drawn in detail and these characters were discussed on species, genera and tribus levels. While significant differences were observed among the species in genital spicula, coxite, stylus and spermateca, a difference that would reveal a genus discrimination character by evaluating these structures could not be obtained according to the available findings. Photos in stereomicroscope and scanning electron microscope are also given in the text.

Abstract Killifishes (family Aphaniidae) in southern Iran demonstrate long‐time acclimation to extreme euryhaline environments. This study provides a detailed histological and ultrastructural characterization of gill morphology in two sympatric endemic aphaniids, Aphaniops furcatus and Aphaniops hormuzensis , inhabiting an ecologically extreme environment in southern Iran. Specimens were collected from the Khurgu hot‐sulphuric spring in the Hormozgan River System which drains into the Persian Gulf, and examined using haematoxylin and eosin (H&amp;E) staining and scanning electron microscopy (SEM). Both species exhibited gill structures typical of teleosts, with primary and secondary lamellae essential for efficient gas exchange. In A. furcatus , gills displayed variations linked to size and gender, with numerous secondary lamellae and a variety of epithelial cells, including squamous, chloride, mucus, blood, and pillar cells. Air exposure led to interlamellar cell masses (ILCM) growth, reducing the lamellae surface area. In A. hormuzensis , gill arches featured a double row of primary filaments with secondary lamellae facilitating oxygen exchange, supported by pillar cells and dense distribution of mucous cells throughout the epithelium. The study highlights the adaptive mechanisms of A. furcatus in response to fluctuating environmental conditions and underscores the evolutionary conservation of gill morphology among teleosts. These findings provide crucial insights into respiratory efficiency and ecological adaptability, emphasizing eco‐evolutionary acclimation to extreme aquatic habitats.

Abstract Caterpillars have a significant impact on human economy, because their plant‐attacking and silk‐producing habits. The larval mouthparts play a crucial role in feeding and spinning and exhibit an extremely morphological diversity, which is closely related to their taxonomic status, feeding habits, and even the developmental stages. However, the larval mouthparts have not been fully elucidated in the megadiverse Sphingidae. In this study, the larval mouthparts of Ampelophaga rubiginosa Bremer &amp; Grey, 1853, Laothoe amurensis (Staudinger, 1892), Smeritus planus Walker, 1856, Dolbina tancrei Staudinger,1887, Phyllosphingia dissimilis (Bremer, 1861), and Marumba sperchius (Ménétriés, 1857) were morphologically observed and compared using scanning electron microscopy. The mouthparts of six species are morphologically diverse on the labral notches, mandibles, spinneret and labial palps arrangement of the mouthparts. The morphological diversity of larval mouthparts is briefly discussed, considering their taxonomical and functional aspects.

Abstract Otolith features (length, width and weight) of 74 individuals of Anguilla anguilla collected from the Söke District of Aydın Province in Western Anatolia, Türkiye were studied for the first time to evaluate the level of asymmetry in the otolith features selected for this study. The asymmetry value of the otolith length was greater than that of otolith width and otolith weight. The asymmetry value of the three otolith features increased with an increase in the fish's length. The likely cause of asymmetry in the otolith parameters examined has been discussed in relation with the variability in growth provoked by ecological influence associated with the discrepancy in habitat setting and contaminants present in the Söke District of Aydın Province in Western Anatolia, Türkiye.

Abstract The human chin, also frequently referred to as the mental prominence, is a part of the human anatomy whose evolutionary origin and function have divided scientific opinion to this day. There were suggestions it could have been used in defence, assisted in the mastication process, aided in the formation of words (i.e. speaking), or that it played a role in mate choice. None of these explanations were satisfactory. This paper, backed up by observations on people from different parts of the world and cultures, using their chin to hold or clamp down objects resting on a person's arms in front of the body or to free the person's hands for other tasks, offers an explanation that has support from results on the evolution of bipedalism from apes to bipedal australopithecines, including Homo sapiens , and the importance of the hands in hominids as well as the heritability of the trait.
