There are different variations of myomere activation depending on the type of swimming or movement. For example, high loading situations such as fast-starts and turning require almost maximal myomere activation in teleost fish. Further, if swim speeds are lower and movement is in one plane, there is less activation of myomeres.
Except for the size, the species are very similar in general appearance, differing mainly in the number of myotomes and the pigmentation of their larvae. [47] They have a translucent, somewhat fish-like body, but without any paired fins or other limbs. A relatively poorly developed tail fin is present, so they are not especially good swimmers.
Fish without these features use dynamic lift instead. It is done using their pectoral fins in a manner similar to the use of wings by airplanes and birds. As these fish swim, their pectoral fins are positioned to create lift which allows the fish to maintain a certain depth. The two major drawbacks of this method are that these fish must stay ...
A myotome is the group of muscles that a single spinal nerve innervates. [1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum). [2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.
The myotome is that part of a somite that forms the muscles of the animal. [2] Each myotome divides into an epaxial part (epimere), at the back, and a hypaxial part ...
A fairly large marine fish for the aquarium with a royal blue body, yellow tail, and black palette design on their body. A star on the silver screen, as Dory in the Disney/Pixar movie Finding Nemo .
The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish, or colloquially as gouramies (which more precisely refers to the family Osphronemidae). Some labyrinth fish are important food fish, and many others, such as the Siamese fighting fish and paradise fish , are popular as aquarium fish.
