Morphology of the feeding apparatus in two oxudercine gobies, Parapocryptes serperaster (Richardson 1846) and Pseudapocryptes elongatus (Cuvier 1816)

Gill arch and raker morphology of common carp (Cyprinus carpio, Linnaeus, 1758) sampled in aquaculture system

“…pagrus, B. boops (Alsafy, Seif, et al, 2022), Epinephelus marginatus (Alsafy & El-Gendy, 2022), Sphyraena sphyraena (Hanafy, 2022), Chaca chaca (Mistri et al, 2016), Corydoras paleatus (Plaul et al, 2021), Siniperca chuatsi (Tran et al, 2022), Labeotropheus fuelleborni, Tropheops (Zogbaum et al, 2021). They are designated as the first, second, third and fourth gills.…”

“…The current research has determined that C. carpio possesses four‐gill arches on either side of its body. These gill arches are arranged in a lateral to medial sequence, similar to the majority of teleost fishes; S. luridus , P. pagrus , B. boops (Alsafy, Seif, et al, 2022), Epinephelus marginatus (Alsafy & El‐Gendy, 2022), Sphyraena sphyraena (Hanafy, 2022), Chaca chaca (Mistri et al, 2016), Corydoras paleatus (Plaul et al, 2021), Siniperca chuatsi (Tran et al, 2022), Labeotropheus fuelleborni , Tropheops (Zogbaum et al, 2021). They are designated as the first, second, third and fourth gills.…”

“…It was mentioned that the rakers in the lateral row of the Hemigymnus species are more numerous and longer, while the rakers in the medial row are less numerous and shorter. In rockfish, the gill rakers in the lateral row were shorter than those in the medial row (Tran et al, 2022). The number and size of the lateral and medial rows have been associated with microalgae consumption in fish in turbid waters and muddy environments (Bishop et al, 2022; Tran et al, 2022).…”

“…In rockfish, the gill rakers in the lateral row were shorter than those in the medial row (Tran et al, 2022). The number and size of the lateral and medial rows have been associated with microalgae consumption in fish in turbid waters and muddy environments (Bishop et al, 2022; Tran et al, 2022). Species with an average number of 16–24 gill rakers feed in the benthic niche, while species with more than 30 rakers feed pelagically (Kahilainen et al, 2011).…”

One size does not fit all: Variation in anatomical traits associated with emersion behavior in mudskippers (Gobiidae: Oxudercinae)

“…Traits associated with aquatic-terrestrial movement in fishes have been examined with respect to fin kinematics (Pace and Gibb, 2009), morphological and molecular basis of vision (Sayer, 2005;Hu et al, 2022), vasculatures of skin, gills, and buccoopercular cavities associated with respiration (Zhang et al, 2000;Gonzales et al, 2011), body elongation and compressions (Polgar et al, 2017;Egan et al, 2021), specialization in feeding and diet (Kruitwagen et al, 2007;Ord and Hundt, 2020;Tran et al, 2022), shifts in dominant bacteria in the gut (Guan et al, 2021), vocalizations (Polgar et al, 2011), burrowing behaviors (Ishimatsu et al, 1998;Dinh et al, 2021), candidate genes associated with emersion (You et al, 2014), and the effects of amphibious behavior on population structure (Corush et al, 2022). In many of these examples, multiple behavioral, physiological, and anatomical traits work together to allow fish to emerge.…”
