SUMMARY The feeding kinematics of dwarf and pygmy sperm whales (Kogia sima and K. breviceps) and bottlenose dolphins Tursiops truncatus were characterized and compared incorporating the Ram-Suction Index (RSI). Mean RSI data support a suction feeding strategy for Kogia (-0.67±0.29; mean ± s.d.) and a ram feeding strategy for Tursiops (0.94±0.11; mean ± s.d.). Tursiops displayed two ram-based feeding behaviours: open gape approach, where gape was at least 50% of maximum in the first video field… 
Comparative feeding kinematics and performance of odontocetes: belugas, Pacific white-sided dolphins and long-finned pilot whales
TLDR
Functional variations of suction generation during feeding demonstrate a wider diversity of feeding behaviors in Odontocetes than previously thought, and odontocete suctiongeneration is convergent with that of more basal aquatic vertebrates.
A functional comparison of the hyolingual complex in pygmy and dwarf sperm whales (Kogia breviceps and K. sima), and bottlenose dolphins (Tursiops truncatus)
TLDR
The data suggest that associated orofacial and tongue morphology, particularly the relationship of hyoid shape and tongue retractor muscles, greatly influences suction capability in odontocetes.
Feeding kinematics and performance of basal otariid pinnipeds, Steller sea lions and northern fur seals: implications for the evolution of mammalian feeding
TLDR
Steller sea lions use both suction and biting when foraging but northern fur seals are constrained to a biting feeding mode, which may be ancestral for this clade.
Foraging ecology and niche overlap in pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales from waters of the U.S. mid‐Atlantic coast
TLDR
Results suggest the feeding ecologies of the pygmy and dwarf sperm whales are similar and both species occupy equivalent trophic niches in the region.
A toothless dwarf dolphin (Odontoceti: Xenorophidae) points to explosive feeding diversification of modern whales (Neoceti)
TLDR
It is reported that a new fossil odontocete from the Oligocene of South Carolina that possesses adaptations for suction feeding: toothlessness and a shortened rostrum (brevirostry) and is the earliest obligate suction feeder within the Odontoceti.

Notes on the confirmation of the Dwarf sperm whale Kogia sima Owen, 1866 (Cetacea: Kogiidae) on Venezuelan coasts
TLDR
To definitively establish the presence of the species K. sima in the country, four records are described here, based on the study of morphometric and/or craniometrical comparison of specimens or collected samples, a definite presence of dwarf sperm whale for territorial waters is proposed and therefore an extension in the distribution range for the southern Caribbean.
Bite performance and feeding kinematics in loggerhead turtles (Caretta caretta) within the context of longline fishery interactions
TLDR
Loggerhead bite performance was measured in several size classes of captive-reared juveniles, captive sub-adults and adults, as well as wild loggerheads, and bite force demonstrated that mean maximum post-hatchling bite force was 2.5N and mass was the best predictor of posthatchlings bite force.
Comparative feeding strategies and kinematics in phocid seals: suction without specialized skull morphology
TLDR
Behavioral and kinematic differences exist between suction feeding and biting in seals, indicating thatsuction feeding is a behaviorally flexible strategy and that skull morphology alone does not capture the true diversity of feeding behaviors used by pinnipeds.
Hydrodynamic performance of the minke whale (Balaenoptera acutorostrata) flipper
TLDR
Video footage, photographs and observations of swimming, engulfment feeding and gulping minke whales showed limb positions corresponding to low drag in wind tunnel tests, and were therefore hydrodynamically efficient.

CONVERGENCE IN THE FEEDING MECHANICS OF ECOMORPHOLOGICALLY SIMILAR SPECIES IN THE CENTRARCHIDAE AND CICHLIDAE
TLDR
The ram-suction index (RSI) was developed to identify the relative contributions of ram feeding and suction feeding to shortening the predator-prey distance during the strike and provides a bench mark for evaluating the hydrodynamic consequences of intraspecific, interspecific and interprey variation in strike mechanics.
Functional Morphology of the Sperm Whale (Physeter macrocephalus) Tongue, with Reference to Suction Feeding
Abstract Gross and microscopic examination of the tongue and hyolingual apparatus of the sperm whale (Physeter macrocephalus) revealed numerous dis-tinct differences from those of other toothed
A KINEMATIC STUDY OF SUCTION FEEDING AND ASSOCIATED BEHAVIOR IN THE LONG‐FINNED PILOT WHALE, GLOBICEPHALA MELAS (TRAILL)
TLDR
Analysis of videotaped feeding sequences provides novel documentation of suction feeding in captive juvenile long-finned pilot whales (Globicephala melas) and shows depression and retraction of the large, piston-like tongue generate negative intraoral pressures for prey capture and ingestion.
Comparative Analysis of the Diets of Pygmy Sperm Whales and Dwarf Sperm Whales in Taiwanese Waters
TLDR
The view that pygmy sperm whalesLive seaward of the continental shelf and that dwarf sperm whales live more in coastal waters is supported.
Morphology predicts suction feeding performance in centrarchid fishes
TLDR
A morphological model of force transmission in the fish head was developed and parameterized with measurements from individual fish to reveal a direct trade-off between morphological requirements of feeding on larger prey and the ability to generate subambient pressure while suction feeding on elusive prey.

An Approach to the Rehabilitation of Kogia spp.
TLDR
From the rehabilitation of 13 live-stranded K. breviceps and K. sima over the last decade, it is learned that it is critical to provide supplemental fluids in addition to solid food to maintain continuous activity of the intestinal tract, and that digestibility of squid species typically fed to captive marine mammals was poor.

TLDR
The tongues of several walruses were examined in terms of gross morphology, anatomy and histology, and it is found that the tongue of the walrus is adapted to the manipulation of its main prey: bivalve molluscs.
