Published: 30 June 2022
...Takashi Hara; Shuya Hasegawa; Yasushi Iwatani; Atsuo S. Nishino ABSTRACT Swimming locomotion in aquatic vertebrates, such as fish and tadpoles, is expressed through neuron networks in the spinal cord. These networks are arranged in parallel, ubiquitously distributed and mutually coupled along...

... and bones should be analysed for power production in feeding (or at least as a compromise between swimming and feeding), and cranial muscles and bones should be analysed for their role in transmitting axial power and coordinating buccal expansion. This new framework is already yielding novel insights...

We measured resting metabolic rate (RMR); mean individual RMR was 0.71–1.42 times that of a similarly sized terrestrial mammal and agreed with past measurements that used breath-by-breath and flow-through respirometry. We also measured energy expenditure during submerged swim trials...

Metabolic rates during stationary dives (3.82±0.56 l O 2 min −1 ) were lower than those measured at the water surface (4.64±1.04 l O 2 min −1 ), which did not differ from rates measured during subsurface swimming (4.91±0.77 l O 2 min −1 ). Thus...
