Fishes use a variety of sensory systems to learn about their environments and communicate. Of the various senses, hearing plays particularly important role for fishes in providing information, often from great distances, all around these animals. This information is three spatial dimensions, overcoming limitations other senses such as vision, touch, taste smell. Sound used communication between fishes, mating behaviour, detection prey predators, orientation migration habitat selection. Thus, anything that interferes with ability fish detect respond biologically relevant sounds can decrease survival fitness individuals populations.

Belemnites are an extinct group of Mesozoic coleoid cephalopods with a fossil record ranging from the early Late Triassic [about 240 million years ago (Mya)] to Cretaceous/Palaeogene boundary (65 Mya). were widely distributed, highly abundant and diverse, important component marine food webs. Their internal shells, specifically their low-Mg calcite rostra, have been used as palaeoenvironmental carbonate archives for last 70 years.

Substrate vibrations and their potential effects upon fishes and invertebrates

The Journal of the Acoustical Society of America, Год журнала: 2021, Номер 149(4), С. 2782 - 2790

This paper reviews the nature of substrate vibration within aquatic environments where seismic interface waves may travel along surface substrate, generating high levels particle motion. There are, however, few data on ambient motion close to seabed and substrates lakes rivers. Nor is there information characteristics generated by anthropogenic sources in which have major effects upon fishes invertebrates, all primarily detect We therefore consider how monitor describe gained from modeling it.

Intra- and interspecific variability among congeneric Pagellus otoliths

Scientific Reports, Год журнала: 2021, Номер 11(1)

Опубликована: Авг. 11, 2021

Otolith features are useful tools for studying taxonomy, ecology, paleontology, and fish biology since they represent a permanent record of life history. Nevertheless, the functional morphology otoliths remains an open research question that is to completely understand their eco-morphology. This study aims deepen knowledge intra- interspecific variation in sagitta three congeneric seabreams, how such variability could be related lifestyles each species. Therefore, sagittae (n = 161) 24 Pagellus bogaraveo, acarne, 37 erythrinus specimens, collected from south Tyrrhenian Sea, were analyzed using scanning electron microscopy stereomicroscope assess morphometric features, between otolith pairs external crystalline structure sulcus acusticus. Statistical analysis demonstrated that, species, sagittal rostral length growth acusticus correlated with increased total body weight. Moreover, slight differences detected P. acarne (P < 0.05). The results confirm changes morphometry different species populations same habitats.

Otoliths are used in taxonomy and ichthyology as they can provide a wide range of information about specimens. They an essential tool to monitor the most sensitive species for sustainable exploitation level. Despite increasing use sagittae research, their inter- intra-specific variability eco-functionality still poorly explored. This paper aims investigate Mugilidae using morphological morphometrical analysis, well scanning electron microscopy shape analysis. The 74 specimens belonging three different species, collected from coastal lagoon, were analyzed give accurate description morphology, morphometry, crystalline habits. results highlighted intra- inter-specific sagittae, showing differences among slight between left right C. labrosus individuals. Moreover, SEM images showed peculiar crystal organization, with several habits polymorphs. study provides studied deepening knowledge on variations providing data which will be useful future studies otoliths. With this data, it possible improve conservation sustainability habitats.

Abstract Locating sound sources such as prey or predators is critical for survival in many vertebrates. Terrestrial vertebrates locate by measuring the time delay and intensity difference of pressure at each ear 1–5 . Underwater, however, physics makes interaural cues very small, suggesting that directional hearing fish should be nearly impossible 6 Yet, has been confirmed behaviourally, although mechanisms have remained unknown decades. Several hypotheses proposed to explain this remarkable ability, including possibility evolved an extreme sensitivity minute differences might compare with particle motion signals 7,8 However, experimental challenges long hindered a definitive explanation. Here we empirically test these models transparent teleost Danionella cerebrum , one smallest 9,10 By selectively controlling motion, dissect sensory algorithm underlying acoustic startles.

Population-level shape variation and otolith asymmetry in Diplodus annularis

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 20, 2025

Sound detection in fishes relies on the inner ear and peripheral structures, such as calcareous otoliths, which play a crucial role perceiving movement, orientation, balance. Otoliths, particular, respond to various environmental factors including temperature, salinity, food availability, making them valuable indicators of ecological conditions. This study applies geometric morphometrics (GMM) analyze otolith shape Diplodus annularis (Linnaeus, 1758) from two distinct populations located Gulf Asinara (Porto Torres, Sardinia) northern Adriatic Sea (Le Tegnue). By using GMM techniques, precise quantifiable differences morphology were revealed between populations, demonstrating significant variation. In addition, fluctuating asymmetry (FA), serves marker for developmental stability stress, was assessed. The results show marked disparities FA populations: samples Porto Torres exhibited posterior asymmetry, while Le Tegnue showed anterior region otoliths. These findings underscore sensitivity detecting even subtle morphological differences, it powerful tool studying genetic influences marine species.
