“…Comparatively, the number and nature of substitutions observed along the transitional branch in the South American freshwater anchovies suggests a less substantial shift in protein function. This may reflect the highly visual nature in the primarily piscivorous croakers in contrast to the most planktivorous and less-active feeding anchovies ( Sasaki 1989 ; Van Nynatten et al. 2015 ).…”

“…Known as croakers or drum because many species use vibrations of their swim bladder to produce acoustic signals ( Ramcharitar et al. 2006 ), the Sciaenids are a family of 286 species of fishes, distributed worldwide, mainly in tropical and subtropical regions ( Sasaki 1989 ). Croakers inhabit nearshore marine habitats and estuaries, and freshwater species occur in rivers of southeast Asia, North America, and South America.…”

Rhodopsin, the light-sensitive visual pigment expressed in rod photoreceptors, is specialized for vision in dim light environments. Aquatic environments are particularly challenging for vision due to the spectrally-dependent attenuation of light, which can differ greatly in marine and freshwater systems. Among fish lineages that have successfully colonized freshwater habitats from ancestrally marine environments, croakers are known as highly visual benthic predators. In this study, we isolate rhodopsins from a diversity of freshwater and marine croakers, and find that strong positive selection in rhodopsin is associated with a marine to freshwater transition in South American croakers. In order to determine if this is accompanied by significant shifts in visual abilities, we resurrected ancestral rhodopsin sequences, and tested the experimental properties of ancestral pigments bracketing this transition using in vitro spectroscopic assays. We found the ancestral freshwater croaker rhodopsin is red-shifted relative to its marine ancestor, with mutations that recapitulate ancestral amino acid changes along this transitional branch resulting in faster kinetics that are likely to be associated with more rapid dark adaptation. This could be quite advantageous in freshwater due to the red-shifted spectrum and relatively narrow interface and frequent transitions between bright and dim light environments. This study is the first to experimentally demonstrate that positively selected substitutions in ancestral visual pigments alter protein function to freshwater visual environments following a transition from an ancestrally marine state, and provides insight into the molecular mechanisms underlying some of the physiological changes associated with this major habitat transition.

“…The Clupeidae comprises sardines with neritic pelagic habits, with Platanichthys representing an endemic monotypic genus in the Southwest Atlantic (Menezes et al, 2003;Whitehead, 1985), including the Argentine Province. Fishes of the Sciaenidae are found in demersal-benthic regions on the coasts of tropical, subtropical and temperate seas, including estuarine and freshwater environments; its origin is Tethyan (Sasaki, 1989).…”

The ichthyofaunistic colonization and complex biogeographic history of the southern portion of the Southwest Atlantic Ocean

et al. 2023

Here, we highlight the geological processes that resulted in the current conformation of the southern Southwest Atlantic Ocean, and explore the heterogeneous composition of the marine ichthyofauna found between 33° and 56° from a paleobiological perspective. During the early Cretaceous (140 Mya), the South Atlantic was still not formed, and Gondwana was probably a set of united plates with shallow continental waters. In the middle Cretaceous (112 Mya), the major Gondwanan plates started diverging from each other, allowing shallow marine intrusions and the diversification of an endemic fish fauna. By the end of the Mesozoic (66 Mya), the proto‐South Atlantic connected with the North Atlantic, which was still part of the Tethys Sea, allowing its ichthyofauna to colonize the south and reach the Antarctic region. The opening of the Drake Passage in the Oligocene (33 Mya) enabled the cold waters of the Pacific Ocean to reach the South Atlantic, causing drastic effects on the thermophilic fauna and favoring the dispersion of cold‐water species. Successive glaciations during the Quaternary (2 Myr to 10,000 years ago) resulted in the prevalence of Antarctic climatic conditions in the southern Southwest Atlantic. The long history of changing scenarios in the constitution of the southern Southwest Atlantic is reflected in the heterogeneous composition of the marine ichthyofauna between 33° and 56°S, which is characterized by a mixture of cosmopolitan, Tethyan, Pacific, Gondwanan, Antarctic, and endemic origins.

Two new species of the sciaenid genus Johnius (Johnius) are described: J. trewavasae from Taiwan, Hong Kong, and Singapore, differs from all other congeners in having 24-27 dorsal soft rays, 5 -6 scales above and 7-10 scales below the lateral line, 6-8 obtuse lower gill rakers, the last pleural rib on the 11th vertebra, and a shorter lower jaw (33.8-38.4% HL); J. latifrons from Thailand and Java is characterized by 25-29 dorsal soft rays, 7-9 scales above and 11-14 scales below the lateral line, 7-9 obtuse lower gill rakers, a wide interorbital width (26.1-30.6% HL), a small eye (16.7-26.4% HL), and a short, second anal spine (25.9-37.1% HL). Two related species, J. heterolepis Bleeker from "Suriname" and J. cantori Bleeker from Malaya, are resurrected as valid West Pacific species of Johnius (Johnius).Johnius is the largest and taxonomically the most confused genus within the Indo-West Pacific Sciaeni dae. Trewavas (1977) recognized 18 valid species, assigned to two subgenera, Johnius and Johnieops, the latter being characterized by a row of enlarged teeth on the lower jaw. Within the subgenus Johnius, Trewavas (1977) recognized 10 valid species. How ever, the addition of J. carouna (Cuvier, 1830) by Mohan (1983Mohan ( , 1984, J. grypotus (Richardson, 1846) by Sasaki (1990), J. glaucus (Day, 1876) by Mohan (1983) and Sasaki and Kailola (1991), and J. laevis Sasaki and Kailola, 1991, brought the number of species to 14. This paper adds two new species of Johnius (Johnius) from the West Pacific. In addition, the status of two species of questionable identity, J. heterolepis Bleeker, 1873, from "Suriname" and J. cantori Bleeker, 1874, from Malaya, is also discussed.Counts and measurements follow Sasaki and Kai lola (1988). Selected head length and eye diameter proportions are given to enable direct comparison with data from Trewavas (1977). Osteological de scriptions are based on radiographs (not available for J. heterolepis syntypes). Institutional abbrevia tions follow Leviton et al. (1985). Standard length and head length are expressed as SL and HL, respec tively. Counts and measurements of the paratypes of the new species are given in parentheses.Johnius (Johnius) trewavasae sp. nov.
