prey capture
- Angling-induced injuries have a negative impact on suction feeding performance and hydrodynamics in marine shiner perch, Cymatogaster aggregata
Summary: Injuries to the mouth caused by fishing hooks reduce suction feeding performance in marine surfperch by altering the flow of water into the mouth during suction.
- Comparative feeding strategies and kinematics in phocid seals: suction without specialized skull morphology
Summary: Behavioral and kinematic differences exist between suction feeding and biting in seals. Suction feeding is common in seals and can occur without specialized skull morphology.
- Tuning orb spider glycoprotein glue performance to habitat humidity
Summary: Viscous capture thread extends an orb spider's phenotype as a highly integrated complex of large proteins and small molecules that function as a self-assembling, highly tuned, environmentally responsive, adhesive biomaterial.
- Hunting with sticky tape: functional shift in silk glands of araneophagous ground spiders (Gnaphosidae)
Editors’ Choice: Gnaphosid spiders utilize sticky, extensible piriform silk to subdue hazardous prey. This derived use of attachment silk comes with strong modifications of the spinning apparatus and reduces the ability to attach structural silk threads.
- Archer fish jumping prey capture: kinematics and hydrodynamics
Highlighted Article: Archer fish are unique aquatic predators capable of jumping multiple body lengths straight up out of the water using oscillatory caudal fin kinematics, in concert with other fins, for propulsion and stabilization.
- Patterns of variation in feeding strike kinematics of juvenile ghost praying mantis (Phyllocrania paradoxa): are components of the strike stereotypic?
Summary: Praying mantises modulate stereotypic components of their feeding strike through the flexibility in the coxa–prothorax joint and amount of lunge from the mesothoracic and metathoracic legs.
- Body ram, not suction, is the primary axis of suction-feeding diversity in spiny-rayed fishes
Summary: Acanthomorph fishes exhibit a large diversity of suction-feeding behaviors, which is driven by variation in the contribution of body ram. Suction distances are constrained even at broad evolutionary scales.
- Single-click beam patterns suggest dynamic changes to the field of view of echolocating Atlantic spotted dolphins (Stenella frontalis) in the wild
Summary: Free-ranging Atlantic spotted dolphins dynamically adjust their sonar beam width to expand their acoustic field of view when approaching targets, potentially decreasing the risk of prey evasion.
