Lunge feeding in early marine reptiles and fast evolution of marine tetrapod feeding guilds

Traditional wisdom holds that biotic recovery from the end-Permian extinction was slow and gradual, and was not complete until the Middle Triassic. Here, we report that the evolution of marine predator feeding guilds, and their trophic structure, proceeded faster. Marine reptile lineages with unique feeding adaptations emerged during the Early Triassic (about 248 million years ago), including t...

Evolution of Feeding Structures in the Marine Nematode Order Enoplida.

Marine nematodes of the order Enoplida may represent the earliest lineage of nematodes and have a variety of fixed and movable feeding structures in their stomas. This study used an 18S ribosomal RNA phylogeny of the orders Enoplida and Triplonchida (subclass Enoplia) to explore the evolution of these feeding structures in light of previous hypotheses based solely on morphology. The Enoplida an...

Feeding habits of Grey sharpnose shark Rhizoprionodon oligolinx Springer, 1964 in marine waters of eastern Hormozgan province

Feeding habits of Grey sharpnose shark Rhizoprionodon oligolinx Springer, 1964 in coastal waters of eastern Hormozgan province from Bandar Sirik to Bandar Jask were studied by sampling 30 fish per month throughout one year. Mean values of fish total length and fish weight was 101.04 ± 4.09 cm and 1480.11 ± 94.71 g. The highest value of gastrosomatic index (GSI) was in spring and the lowest was ...

Kinematics of foraging dives and lunge-feeding in fin whales.

Fin whales are among the largest predators on earth, yet little is known about their foraging behavior at depth. These whales obtain their prey by lunge-feeding, an extraordinary biomechanical event where large amounts of water and prey are engulfed and filtered. This process entails a high energetic cost that effectively decreases dive duration and increases post-dive recovery time. To examine...
