Supramedullary Neurons in Teleost Fishes: Distribution and Putative Functions

“…One way to gain insight into SMN function will be to record their activity in free‐swimming fishes. Pufferfishes provide the preferred preparation for such an approach since SMNs are large and clustered over the medulla oblongata and spinal cord surface (see figures in Hagiwara and Saito 1959; Bennett et al 1959a; Uehara et al 2000). SMNs are mutually excitatory and respond in synchrony and often repetitively to tactile stimulation in the Atlantic pufferfish (Bennett et al 1959c) and Sargassum fish ( Histrio sp., Bennett et al 1967), and extracellular potentials can be recorded from these neurons (Bennett et al 1967).…”

Thriving artificial underwater drag-reduction materials inspired from aquatic animals: progresses and challenges

“…31 To further reveal the effect and exibility of studying the drag reduction of puffer, Zhou, Cui, et al established the 3D curved surface structure of puffersh and expanded their surface into planes for analysis. 117 Inspired by the body spines of the puffersh, 118,119 the simulation shows that the drag reduction rate of the non-smooth surface imitating the body spur of the puffer is 12.94% when the water velocity is 5 m s À1 . 116 However, the scales of some sh are also considered to have no drag reduction.…”

The shortened spinal cord in tetraodontiform fishes

“…Owen (1866) also noted that the spinal cord in the Diodontidae and Tetraodontidae is short. Uehara and Ueshima (1986), and Uehara et al (2000) reported macroscopically, histologically, and embryologically that the spinal cord in the Tetraodontidae and Monacanthidae is prominently shortened, forming a flat filum terminale with the cauda equina. They suggested that the spinal cord might be shortened in tetraodontiform fishes in general.…”
