Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Small pelagic fish feeding from the eastern Adriatic Sea [PDF]

open access: yes, 2019
Diet of five small pelagic fish species (sardine, anchovy, round sardinella, chub mackerel and horse mackerel) and their possible food overlap was studied in the eastern Adriatic Sea, from June 2014 to August 2016. Sardine and anchovy fed mainly on copepods, while decapod larvae, together with megalopa stage, appeared to be the most important food ...

The humble sardine (small pelagics): fish as food or fodder [PDF]

open access: yesAgriculture & Food Security, 2016
The group of small pelagic fish is the largest species group landed globally. A significant proportion of this nutrient-rich food is processed and lost to livestock feed, fish feed, fish oil, pet food and omega-rich vitamins. The nutritional importance of small pelagics as an easily digestible protein source, rich in essential lipids with fatty acids ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.
