An integrated approach to understanding the role of the long neck in plesiosaurs [PDF]

open access: yesActa Palaeontologica Polonica, 2017
The evolution and function of the long neck in plesiosaurs, and how the problems associated with stiffness or flexibility were overcome during feeding, or rapid swimming during predator avoidance, are explored, and a new interpretation for the function ...

Hydrodynamic analysis of bioinspired vortical cross-step filtration by computational modelling

open access: yesRoyal Society Open Science, 2023
Research on the suspension-feeding apparatus of fishes has led recently to the identification of novel filtration mechanisms involving vortices. Structures inside fish mouths form a series of ‘backward-facing steps' by protruding medially into the mouth ...

Bivalve Feeding on the Brown Tide Aureoumbra lagunensis in a Shallow Coastal Environment

open access: yesFrontiers in Marine Science, 2021
Brown tides formed by Aureoumbra lagunensis decrease light penetration in the water column and are often followed by hypoxic events that result in the loss of fish and shellfish.

A new Early Oligocene toothed ‘baleen’ whale (Mysticeti: Aetiocetidae) from western North America: one of the oldest and the smallest [PDF]

open access: yesRoyal Society Open Science, 2015
Archaic toothed mysticetes represent the evolutionary transition from raptorial to bulk filter feeding in baleen whales. Aetiocetids, in particular, preserve an intermediate morphological stage in which teeth functioned alongside a precursor of baleen ...

Salishicetus meadi, a new aetiocetid from the late Oligocene of Washington State and implications for feeding transitions in early mysticete evolution [PDF]

open access: yesRoyal Society Open Science, 2018
Living baleen whales, or Mysticeti, lack teeth and instead feed using keratinous baleen plates to sieve prey-laden water. This feeding strategy is profoundly different from that of their toothed ancestors, which processed prey using the differentiated ...

Hydrodynamics of sponge pumps and evolution of the sponge body plan

open access: yeseLife, 2020
Sponges are suspension feeders that filter vast amounts of water. Pumping is carried out by flagellated chambers that are connected to an inhalant and exhalant canal system.

Filter-Feeding Pacific Lamprey (Entosphenus tridentatus) Ammocetes Can Reduce Suspended Concentrations of E. coli Bacteria

open access: yesFishes, 2023
Filter-feeding invertebrates such as bivalves have been shown to improve the health of aquatic systems by reducing concentrations of bacteria and other harmful suspended organisms, but it remains unknown if microphagous suspension-feeding fishes can ...

RETRACTED ARTICLE: Lateral palatal foramina do not indicate baleen in fossil whales

open access: yesScientific Reports, 2022
Today’s mysticetes filter-feed using baleen, a novel integumentary structure with no apparent homolog in any living mammal. The origins of filter-feeding and baleen can be informed by the fossil record, including rare instances of soft tissue ...

Omnivory by planktivores stabilizes plankton dynamics, but may either promote or reduce algal biomass [PDF]

open access: yes, 2010
Classical models of phytoplankton–zooplankton interaction show that with nutrient enrichment such systems may abruptly shift from limit cycles to stable phytoplankton domination due to zooplankton predation by planktivorous fish.

From the surface to the seafloor: How giant larvaceans transport microplastics into the deep sea. [PDF]

open access: yes, 2017
Plastic waste is a pervasive feature of marine environments, yet little is empirically known about the biological and physical processes that transport plastics through marine ecosystems.
