Acoustic tracking of bigeye thresher shark Alopias superciliosus in the eastern Pacific Ocean

Acoustic telemetry was used to identify the short-term horizontal and vertical movement patterns of the bigeye thresher shark Alopias superciliosus in the eastern tropical Pacific Ocean during the summer of 1996. Two immature female sharks, 175 and 124 cm PCL (precaudal length), were tracked for 96 and 70 h, respectively, demonstrating very distinct crepuscular vertical migrations similar to th...

Co-evolution of movement behaviours by tropical pelagic predatory fishes in response to prey environment: a simulation model

Predatory fishes, such as tunas, billfishes, and sharks, coexist in pelagic regions of the tropical oceans. In situ experiments have revealed horizontal and vertical movement patterns for different pelagic species, but the influence of the biotic environment on movement behaviour has not been studied. In this paper, we propose a simple model in which the movement behaviour of these fishes is dr...

Structural adaptations for ram ventilation: gill fusions in scombrids and billfishes.

For ram-gill ventilators such as tunas and mackerels (family Scombridae) and billfishes (families Istiophoridae, Xiphiidae), fusions binding the gill lamellae and filaments prevent gill deformation by a fast and continuous ventilatory stream. This study examines the gills from 28 scombrid and seven billfish species in order to determine how factors such as body size, swimming speed, and the deg...

Gill morphometrics in relation to gas transfer and ram ventilation in high-energy demand teleosts: scombrids and billfishes.

This comparative study of the gill morphometrics in scombrids (tunas, bonitos, and mackerels) and billfishes (marlins, swordfish) examines features of gill design related to high rates of gas transfer and the high-pressure branchial flow associated with fast, continuous swimming. Tunas have the largest relative gill surface areas of any fish group, and although the gill areas of non-tuna scombr...

Co-evolution of movement behaviors by tropical pelagic predatory fishes in response to prey environment: A simulation model

Tropical oceanic fishes, such as tunas, billfishes, and sharks, live together in the same environment – the pelagic open ocean. In situ experiments have been developed to observe horizontal and vertical movements of individuals of different pelagic species, but the fact that these species share the same environment has not been studied yet. In this paper we propose a minimal model in which the ...
