Convergent Evolutionary Dead-End and Breakdown of Hard Chorion in Parental-Egg-Care Fish Reproductive Strategies. [PDF]
Mol EcolABSTRACT Fish exhibit a diverse array of reproductive strategies adapted to various ecological niches. Parental egg‐care, including live‐bearing, mouth‐brooding, and male egg protection by brood pouches, represents an effective strategy for ensuring larval survival and has emerged independently in multiple lineages.

Submissions of diagnostic samples of two critically endangered species of handfish (Branchionichthys hirsutus and Thymichthys politus) from a public aquarium from 2018 to 2024. [PDF]
J Fish DisAbstract Handfish (Family Brachionichthyidae) is the most threatened marine teleost fish family, however, there is little information on handfish health. We reviewed the results of submissions of mortalities from captive and captive bred spotted handfish (Branchionichthys hirsutus (Lacepède, 1804)) and red handfish (Thymichthys politus (Richardson ...

Design and Validation of an Open-Close Device for Integrated Environmental DNA Sampling Detects A Depth Gradient in Indian Ocean Deep-Sea Fish Assemblages. [PDF]
Ecol EvolThe goal of this study was to leverage existing survey technology to design and test an eDNA sampler that captures an integrated eDNA sample over the length of a deep‐water transect. We provide a biological interpretation of the resulting data, demonstrating the usefulness of such technology to understand the ocean environments, using fish species as ...

Scientia Marina, 2020 Anglerfishes are widely distributed from shallow to deep-water habitats occupying different ecological niches. To explain this adaptability, we performed a morpho-functional study on common benthic anglerfishes inhabiting the Indian deep-sea waters ...

Records of anglerfishes (Actinopterygii: Lophiiformes: Lophiidae) from Indonesia [PDF]
Acta Ichthyologica et Piscatoria, 2016 Background. The lophiid anglerfishes are with commercial importance, but rarely they are documented in Indonesian waters. During the Japanese and Indonesian collaborative surveys in 2004 and 2005, an anglerfish collection was made and it is the aim of ...

Ecology and Evolution, Volume 13, Issue 12, December 2023., 2023 The fish fauna of the beibu gulf, one of the largest sea food hubs in Southeast Asia, is characterized here by DNA barcoding. The 1080 DNA barcodes analyzed show concordance between morphological identifications and DNA‐based species delimitation. Lower level of diversity detected here compared to historical observations is concordant with the stock ...

Lymphocyte pathway analysis using naturally lymphocyte‐deficient fish
European Journal of Immunology, Volume 53, Issue 12, December 2023., 2023 Loss of phenotypic characters is often accompanied by degradation of trait‐specific genetic components. Genome analysis of teleosts lacking canonical components of the adaptive immune system distinguishes trait‐specific from pleiotropic genes governing lymphocyte differentiation.

Foxn1 is not essential for T‐cell development in teleosts
European Journal of Immunology, Volume 53, Issue 12, December 2023., 2023 In contrast to the situation in mammals, loss of the foxn1 gene in teleosts does not abolish the lymphopoietic capacity of the thymus. This result suggests that in teleosts, genetic control of thymopoiesis is functionally redundant, likely owing to the activity of the Foxn4 transcription factor.

Environmental DNA, Volume 5, Issue 6, Page 1362-1377, November 2023., 2023 This study explores the diet of one of the world's most recognizable predators, the white shark. Dietary assessments are performed by genomic analysis of cloacal swabs collected from approximately 200 live sharks. Findings from this study provide insights into the trophic ecology and feeding behavior of the white shark and key marine resources ...

Skeletal ontogeny of the Plainfin Midshipman, Porichthys notatus (Percomorphacea: Batrachoidiformes)
Journal of Anatomy, Volume 242, Issue 3, Page 447-494, March 2023., 2023 Description of skeletal ontogeny during early life history of Porichthys notatus. Establishment that the previously described as dorsalmost pectoral radial is homologous to the propterygium. Unique developmental pathway of the posterior basibranchial cartilage, first appearing as paired elements which fuse in later stages.
