A. Hagfish, a jawless fish B. Ray - finned fish with multiple fins C. Bony fish with paired fins D. Shark, a cartilaginous fish 相关知识点: 试题来源: 解析 A。解析:身体长像蛇、没有腹鳍并且单个背鳍沿着身体大部分延伸,这是盲鳗(hagfish,一种无颌鱼)的特征。B选项有多个鳍的辐鳍鱼不符合...
The robot fish employs two pectoral fins to generate steering and one caudal fin to generate main propulsion. A passive plastic fin is attached to the IPMC beam to enhance propulsion. With multiple IPMC fins, the fish is capable of 2D maneuvering. One small size programmable circuit board is ...

This paper presents an environment-friendly robotic system mimicking undulating fins of fish. To mimic the actual flexible fin of real fish, we model a fin... KH Low,A Willy - IEEE 被引量: 57发表: 2005年 Amphibious Pattern Design of a Robotic Fish with Wheel-propeller-fin Mechanisms Yang...
In a nutshell: when considering truly unsteady motions like the fast start of a deformable body in aquatic environment, the vortical wake is not sufficient to catch the essence of the maneuver as it would be in presence of a light fluid like air, but the multiple effects associated to the ...
(monoodontode) or multiple odontodes (polyodontode)16,17,18,19,20,21,22. Early osteichthyans, on the other hand, bear large rhomboid scales with a well-developed peg-and-socket articulation23,24,25,26,27,28, which is considered a bony fish synapomorphy29. Osteichthyan scales ...
With multiple awards and a devoted fan base, Said the Whale's place among the best bands named after sea animals remains steadfast. 37 Shark Island 14 votes As part of the late 1980s hard rock scene in Los Angeles, Shark Island stood out with their melodic, guitar-driven sound and ...
The tail is modeled by multiple rigid segments connected in series through rotational springs and dampers, and the hydrodynamic force on each segment is evaluated using Lighthill's large-amplitude elongated-body theory. For comparison, we also construct a model using linear beam theory to capture ...
A preliminary application of the theory to the balance of reactive thrust and resistive drag in regular carangiform swimming of fishes with slender caudal fins is made (section 3). Comparison with data (Bainbridge 1963) on the dace ... Lighthill,M. J. - 《Proceedings of the Royal Society of...
The present study focused on the cells obtained from fish fins, which were often discarded as food waste, and which had the potential to change their morphology with simple treatments, creating the possibility of processing fish fin cells into clean meat (i.e., meat produced in vitro; ...
