He bought it, sent it downtown to get it stuffed and eventually got it delivered to the scanning department of the McLaren Automotive aerodynamics laboratory in Surrey – where the carmakers set to work trying to learn the secrets of the super-speed fish's abilities.
Visitors can build imaginary speed-fish and can examine a jumbo squid, which uses jet propulsion.
At this speed, the fish orientates itself against the current and swims steadily.
In our theoretical analysis, a general conclusion is that optimal ground speeds for fish swimming against currents would increase with increasing current velocity.
To understand the relationship between the speed of fishes and some particular physical parameters of their backbones one may build a swimming robot, intervene on the characteristics of its backbone, and measure the resulting speed in search of a correlation.
For instance, Sogard and Olla [32] found that sablefish undergoing higher compensatory growth exhibited lower critical swimming speeds than fish with average growth rates.
However, recent studies that directly measured the swimming speed of fishes with animal-borne speedometers revealed that sturgeons [9], salmons [17], [18], marlins [19], and blue sharks [20] cruise at a relatively narrow range of speed (0.1 1.0 m s−1).
As tailbeat amplitude tends to show little variation with speed in fishes (e.g. Coughlin et al., 2001), higher frequencies will increase swimming speed.
We assessed how fish speed and survey procedure (visibility, diver speed, survey time and dimensions) affect observed fish counts.
Overall, fish speed had the greatest effect on bias that increased systematically with fish speed up to 61 for the belt-transect and 31 for the stationary-point-count diver for fish moving at 4 m·s−1.
