Does a Spotted eagle ray molt as it grows?

All rays are cartilaginous fish similar to sharks and dogfish and therefore do not molt.  

Explanation:

Spotted eagle rays are viviparous, indicating they deliver live birth. Females are gestating for around one year before producing birth to about two-four adolescents which are seventeen to thirty-five cm large. Spotted eagle rays develop at the period of four to six years old. Spotted Eagle Rays survive for around fifteen-twenty years.

we would need to see the picture to answer it

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
