Histological Studies on the Skin of a Freshwater Goby Rhinogobius brunneus (Gobiidae) Related to Cutaneous Respiration

Histology and morphometry of the skin of purple spaghetti-eel Moringua raitaborua (Anguilliformes, Moringuidae)

“…Many amphibious fishes exhibiting cutaneous respiration contain a thicker ED produced by large secretary cells as follows: 38.4–156.8 μm thick, a freshwater goby Rhinogobius brunneus (Kim et al 2022 ); 35.4–150 μm, a trident goby Tridentiger brevispinis (Kim 2022 ); 136.3–195.5 μm, a mud loach Misgurnus mizolepis (Park et al 2001 ); 146–495 μm, a torrent catfish Liobagrus mediadiposalis (Park et al 2003a ); 59.0 μm 297.0 μm, an eel goby Odontamblyopus lacepedii (Park et al 2003b ), M. raitaborua (246.8 ± 51.5 μm, 139.1–358.0; mean ± SD, range) with CCs and MCs. Reduced diffusion distance of the skin also is strong evidence that confirms more rapid gas-exchange, as measured by an ascending vascularization that represents two histological categories in its occurrence position (Glover et al 2013 ): (i) intraepidermal blood capillaries of the outermost surface layer ( Mastcembellus pancalus with a mean diffusion distance of 34.0 μm; Mittal and Munshi 1971 ; Periophthalmus modestus with a mean of 1.4 μm; Park et al 2000 ), the middle layer ( Liobagrus mediadiposalis with a mean of 169 μm; Park et al 2003a ), and the stratum germinativum ( Rhinogobius brunneus with a range of 35.0–202.6 μm; Kim et al 2022 ), and (ii) well-developed dermal vascularization among collagen fibers of SL just below the basement membrane ( Pseudobagrus brevicorpus , with a range of 19.9–399.4 μm, Park et al 2010 ; abd Tridentiger brevispinis , with a range of 51.4–216.9, Kim 2022 ) (Kazerouni and Khodabandeh 2010 ; Romano et al 2019 ). In this study, M .…”

“…While researching the histology of fishes inhabiting intertidal pools and estuarine standing water, dermal vascularization (as in Rhinogobius brunneus and Tridentiger brevispinis ) was found in the skin of M . raitaborua (Kim 2022 ; Kim et al 2022 ). This study aims to describe the skin structure and analyze the morphometry of the epidermal thickness and diffusion distance of M .…”

Epidermal modifications in a hill stream catfish, Hara hara in relation to its natural habitat: A scanning electron microscope and histochemical investigation

“…Significant progress has been made in recent years in our knowledge of teleost fish skin focusing on surface architecture, histology, histochemistry and fluorescence microscopy. These include Cyprinus carpio (DePasquale, 2018), Hippoglossus hippoglossus (Alves et al, 2018), Chaca chaca (Mistri et al, 2018a, 2018b), Rhinogobius brunneus (Kim et al, 2022), Periophthalmus waltoni and Boleophthalmus dussumieri (Dorostghoal et al, 2022).…”
