Mobulid rays (manta and devil rays) use a highly specialized filtering apparatus to separate plankton food particles from seawater. Recent studies have indicated that captive vortices form within the microscale pores of filter, which enhance filtration efficiency through novel mechanism referred as ricochet separation. The high throughput clog resistance this process led development several bioinspired engineered systems. However, it is still unclear how changes filter morphology influence...
Three lineages of cartilaginous fishes have independently evolved filter feeding (Lamniformes: Megachasma and Cetorhinus, Orectolobiformes: Rhincodon, Mobulidae: Manta Mobula); the structure branchial filters is different in each group. The Rhincodon typus has been described; species within Lamniformes simple filamentous filters, but anatomy ultrastructure mobulid rays varies functional interest. In most fishes, gill rakers are elongated structures located along anterior ceratobranchial...
Experimental and computational fluid dynamics indicate that manta rays use a novel filtration mechanism for feeding.
We created physical models based on the morphology of ram suspension-feeding fishes to better understand roles and swimming speed play in particle retention, size selectivity filtration efficiency during feeding events. varied buccal length, flow architecture gills slits, including number, size, orientation pore size/permeability, our models. Models were placed a recirculating tank with slightly negatively buoyant plankton-like particles (~20-2000 μm) collected at simulated esophagus gill...
ABSTRACT The four, evolutionarily independent, lineages of suspension feeding elasmobranchs have two types branchial filters. first is a robust, flattened filter pad akin to colander (e.g., whale sharks, mantas and devil rays) while the second more closely resembles comb‐like gill raker structure found in bony fishes basking megamouth sharks). presence mucus on elements will determine mechanical function subsequent particle transport. Using histology scanning electron microscopy, we...
We present genetic and morphometric support for a third, distinct, recently diverged group of Manta ray that appears resident to the Yucatán coastal waters Gulf Mexico. Individuals genus from Isla Holbox are markedly different other described manta rays in their morphology, habitat preference, makeup. Herein referred as Ray, these individuals form two genetically distinct groups: (1) mtDNA haplotypes divergent (0.78%) currently recognized birostris M. alfredi species, (2) possessing highly...
Parents in academic careers face notable challenges that may go unrecognized by university management and/or policy makers. The COVID-19 pandemic has shed light on some of these challenges, as parents shifted to working from home while simultaneously caring for children. On the other hand, many found shift offered new opportunities such more flexible hours, development digital skillsets, and increased involvement education their In this article we explore work-related experienced a result...
Given the conservation status and ecological, cultural, commercial importance of chondrichthyan fishes, it is valuable to evaluate extent which research attention spread across taxa geographic locations assess degree scientific appropriately addressing challenges they face. Here we review trends in effort over three decades (1985–2016) through content analysis every abstract (n = 2,701) presented at annual conference American Elasmobranch Society (AES), oldest largest professional society...
Hyperostosis, excessive bone growth along that stems from bone, periosteum or articular epiphyseal cartilage, occurs in at least 22 families of fishes most which are tropical subtropical marine species. While the presence hyperostosis is well documented fishes, mechanism driving development unclear. This study dorsal pterygiophores both sexes oarfish, Regalecus russellii; however, it was not present all specimens examined. second lampridiform fish with hyperostoses and first case a...
The cory catfishes (Callichthyidae) are small, South American armored with a series of dermal scutes that run the length fish from posterior to parieto-supraoccipital down caudal peduncle. In this study, we explore anatomy and functional performance in three-striped catfish, Corydoras trilineatus. lateral surface has dorsal ventral row interact at horizontal septum. have little overlap sequential (~33% overlap) deep ridge internal connects underlying soft tissue. C. trilineatus is stiffer...
Filter-feeding has been present for hundreds of millions years, independently evolving in aquatic vertebrates' numerous times. Mysticete whales are a group gigantic, marine filter-feeders that defined by their fringed baleen and divided into two groups: balaenids rorquals. Recent studies have shown likely feed using self-cleaning, cross-flow filtration mechanism where food particles collected then swept to the esophagus swallowing. However, it is unclear how filtering achieved rorquals...
Reproduction is a critical aspect of understanding the biology fishes. Relatively little known about oarfish (Regalecus russellii) reproduction; however, strandings dead animals have provided rare opportunity to investigate gonadal morphology four fish: two females and males. A female collected in June 2015 (4.32 m TL) had bifurcated ovaries 2.14 length kg. The gonadosomatic index (GSI) was 11.8% fish determined be spawning capable/spawning reproductive phase. that stranded Sept. (5.20 1.43...
Scientific professional societies are reviewing diversity, equity, and inclusion (DEI) practices policies in response to recent calls for much-needed change. Organizations like scientific contribute establishing disciplinary norms, can influence the diversity of workforces multiple ways through both action inaction. This paper examines these issues using American Elasmobranch Society (AES), a medium-sized society, as case study. It consists three parts: (1) an analysis demographics AES...
Abstract The king‐of‐the‐salmon, Trachipterus altivelis (Lampriformes), has an unusual set of oral jaws which allow it the ability to protrude entire upper jaw, containing premaxilla and maxilla bones, extreme distances. Here, we provide a short description cranial anatomy mechanism jaw protrusion in T. using hand‐drawn illustrations (by KF), supplemented by CT‐scans. We then place abilities into context comparing anatomical with from other members Lampriformes, unrelated species highly...
