Definition

Noun: 1. A small, free-floating marine animal of the subphylum Tunicata (sea squirts), characterized by a transparent, barrel-shaped body with openings at both ends. Salps are planktonic organisms that move by pumping water through their gelatinous bodies.

  • The salpa is a filter feeder, straining microscopic plankton from the seawater it pumps through its body.
  • Under the microscope, the simple structure of the salpa is clearly visible.

Advanced Usage

• "Salp chain": Refers to the asexual reproductive phase where many individual salps are connected in a long, linear colony that moves through the water.
