FAQ

Frequently Asked Questions

No. Despite a superficial resemblance, salpas are chordates (tunicates), closely related to vertebrates, while jellyfish are cnidarians.

Yes, many salpa species are several centimetres long and their transparent, gelatinous bodies are visible in clear water.

Almost exclusively in scientific contexts like marine biology research papers, textbooks, and expert documentation.

Not directly, but they play a significant ecological role in carbon cycling by consuming phytoplankton and producing dense fecal pellets that sink.
