A salp (pl.: salps, also known colloquially as “sea grape”) or salpa (pl.: salpae or salpas [2]) is a barrel-shaped, planktonic tunicate in the family Salpidae. It moves by contracting, thereby pumping water through its gelatinous body; it is one of the most efficient examples of jet propulsion in the animal kingdom. [ 3 ]
Pyrosomes are closely related to salps, and are sometimes called "fire salps". Sailors on the ocean occasionally observe calm seas containing many pyrosomes, all luminescing on a dark night. [5] [8] Pyrosomes feed through filtration and they are among the most efficient filter feeders of any zooplankton species.
Ingesting the dreamfish Sarpa salpa can result in hallucinations that last for several days. Several species of fish are claimed to produce hallucinogenic effects when consumed, a condition known as ichthyoallyeinotoxism. For example, Sarpa salpa, a species of sea bream referred to as the "dream-fish", is commonly claimed to be hallucinogenic.
Siphonophorae (from Greek siphōn 'tube' + pherein 'to bear' [2]) is an order within Hydrozoa, which is a class of marine organisms within the phylum Cnidaria.According to the World Register of Marine Species, the order contains 175 species described thus far.
Thaliaceans (pyrosomes, doliolids, and salps) and larvaceans on the other hand, swim in the pelagic zone of the sea as adults. Various species of ascidians , the most well-known class of tunicates, are commonly known as sea squirts , sea pork, sea livers, or sea tulips .
The most commonly encountered organisms include ctenophores, medusae, salps, and Chaetognatha in coastal waters. However, almost all marine phyla, including Annelida, Mollusca and Arthropoda, contain gelatinous species, but many of those odd species live in the open ocean and the deep sea and are less available to the casual ocean observer.

Thaliacea is a class of marine chordates within the subphylum Tunicata, comprising the salps, pyrosomes and doliolids.Unlike their benthic relatives the ascidians, from which they are believed to have emerged, thaliaceans are free-floating for their entire lifespan.
Phronima is a genus of small, deep sea hyperiid amphipods of the family Phronimidae. It is found throughout the world's oceans, except in polar regions. [1] Phronima species live in the pelagic zone of the deep ocean. Their bodies are semitransparent. Although commonly known as parasites, they are more technically correctly called parasitoids. [2]
