The scale-dependence of locomotor factors have long been studied in comparative biomechanics, but remain poorly understood for animals at the upper extremes body size. Rorqual baleen whales include largest animals, we lack basic kinematic data about their movements and behavior below ocean surface. Here combined morphometrics from aerial drone photogrammetry, whale-borne inertial sensing tag data, hydrodynamic modeling to study locomotion five rorqual species. We quantified changes tail...
The whale watching industry in Juneau, Alaska relies primarily on the presence of North Pacific humpback whales (Megaptera novaeangliae). To meet demands from rapidly growing tourism industry, number vessels this region has tripled over last 18 years. As a result, increased vessel could have negative effects whales, ranging short-term behavioral disturbance to long-term impacts. current viewing regulations are outdated and may not be as effective they were years ago, when both population...
ABSTRACT Despite their enormous size, whales make living as voracious predators. To catch much smaller, more maneuverable prey, they have developed several unique locomotor strategies that require high energetic input, mechanical power output and a surprising degree of agility. better understand how body size affects maneuverability at the largest scale, we used bio-logging data, aerial photogrammetry high-throughput approach to quantify maneuvering performance seven species free-swimming...
Abstract Whale watching can affect cetacean behaviour, and in some cases lead to long‐term negative effects on survival reproduction. The waters of Juneau (Alaska) represent a summer feeding ground for the Central North Pacific stock humpback whales, Megaptera novaeangliae (Borowski, 1781). recent dramatic expansion local whale‐watching industry has raised concerns over potential impact such activity whales. aim this study was understand vessels whale behaviour Juneau. From June September...
The considerable power needed for large whales to leap out of the water may represent single most expensive burst maneuver found in nature. However, mechanics and energetic costs associated with breaching behaviors remain poorly understood. In this study we deployed whale-borne tags measure kinematics test hypothesis that these spectacular aerial displays are metabolically expensive. We use variable underwater trajectories, high-emergence breaches faster require more energy than predatory...
High efficiency lunate-tail swimming with high-aspect-ratio lifting surfaces has evolved in many vertebrate lineages, from fish to cetaceans. Baleen whales (Mysticeti) are the largest animals that exhibit this locomotor strategy, and present an ideal study system examine how morphology kinematics of scale body sizes. We used data whale-borne inertial sensors coupled morphometric measurements aerial drones calculate hydrodynamic performance oscillatory six baleen whale species ranging length...
Abstract Recent changes in the South African marine ecosystem and introduction of an experimental octopus fishery have resulted unsustainably high rate fatal Bryde's whale entanglements. Using suction‐cup attached bio‐loggers, we identified a previously undescribed feeding behavior used by whales to catch prey, this may make them susceptible entanglement mortality bottom‐mounted fishing gear. As they chase down their inshore sprint maneuver along seafloor for extended periods time, making...
