Abstract: The axial musculature of fishes has historically been characterized as the powerhouse for explosive swimming behaviors. However, recent studies show that some fish also use their ‘swimming’ muscles to generate over 90% of the power… read more here.

Abstract: The complex interplay between form and function forms the basis for generating and maintaining organismal diversity. Fishes that rely on suction-feeding for prey capture exhibit remarkable phenotypic and trophic diversity. Yet the relationships between fish… read more here.

Abstract: Research on the water-to-land transition tends to focus on the locomotor changes necessary for terrestriality. But the evolution from water breathing to air breathing was also a necessary precursor to the invasion of land. Air… read more here.

DOI: 10.1098/rspb.2021.1968
Abstract: Suction-feeding in fishes is a ubiquitous form of prey capture whose outcome depends both on the movements of the predator and the prey, and on the dynamics of the surrounding fluid, which exerts forces on… read more here.

DOI: 10.1242/jeb.178160
Abstract: ABSTRACT Suction-feeding fish rapidly expand the mouth cavity to generate high-velocity fluid flows that accelerate food into the mouth. Such fast and forceful suction expansion poses a challenge, as muscle power is limited by muscle… read more here.

Abstract: Simple Summary Skull and jaw shape are critical to how an animal eats. The goal of this work was to examine how facial variation evolves and the genetic basis of these changes. We used two… read more here.

In vivo intraoral waterflow quantification reveals hidden mechanisms of suction feeding in fish

DOI: 10.7554/elife.73621
Abstract: Virtually all fishes rely on flows of water to transport food to the back of their pharynx. While external flows that draw food into the mouth are well described, how intraoral waterflows manage to deposit… read more here.
