GENERAL HISTOLOGY

Detailed explanation-1: -Ctenophores are planktonic organisms that are jelly-like in form but, unlike true jellies, they propel themselves by beating rows of compound cilia in waves. Their movement is therefore very gentle and gradual. The compound cilia occur in comb rows, five longitudinal rows on the body.

Detailed explanation-2: -Ctenophores, or comb jellies, are the largest animals to move using cilia. In ctenophores, cilia are specialized to function together as a pack or comb. While moving, the cilia refract white light into rainbow-colored pulses that appear to move along the body of the ctenophore.

Detailed explanation-3: -Most jellyfish have long stinging tentacles and have oral-arms that help catch and eat food. Comb jellies have oval bodies lined with rows of fluttering cilia. Instead of stinging, they use their tentacles to pull prey into their large mouths.

Detailed explanation-4: -Ctenophores move through the water by beating their comb rows-they are the largest animals to move entirely by ciliary movements-but they also have a complex array of definitive muscle cells.

Detailed explanation-5: -The proximal CL provides a strong building foundation, while the distal CL ensures an elastic connection between cilia. Together, these proteins found in the CL maintain the rippling movement that propels comb jellies through their ocean environment.
