Unrevealing Parasitic Trophic Interactions—A Molecular Approach for Fluid-Feeding Fishes

open access: yesFrontiers in Ecology and Evolution, 2018
Fish diets have been traditionally studied through the direct visual identification of food items found in their stomachs. Stomach contents of Vandeliinae and Stegophilinae (family Trichomycteridae) parasite catfishes, however, cannot be identified by ...

Partners or passengers? Revisiting the association between diatoms and aquatic animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Coagulation of Catfish Blood

open access: yesExperimental Biology and Medicine, 1965
SummaryThe blood of the fresh water catfish (Ameiurus nebulosus) clots rapidly. There appears to be species specificity of the prothrombin-thromboplastin reaction with both the one- and two-stage methods. Catfish brain thromboplastin causes rapid clotting of catfish plasma, but acts as a partial thromboplastin with canine plasma.

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Does the hearing sensitivity in thorny catfishes depend on swim bladder morphology?

open access: yesPLoS ONE, 2013
BackgroundThorny catfishes exhibit large variations in swim bladder morphology. These organs are of different sizes, forms and may have simple or branched diverticula.
