Culturing tunicates on a large scale may be possible and the economics of doing so are attractive. As tunicates have few predators, their removal from the sea may not have profound ecological impacts. Being sea-based, their production does not compete with food production as does the cultivation of land-based crops for biofuel projects. [70]
Tunicates are a subphylum of the Chordata and occupy a diverse range of marine habitats such as shallow water, near shore, open ocean, and the deep sea. [1] Tunicates are invertebrates, and their bodies are surrounded by a tunic resembling cartilage, composed of proteins, carbohydrates, and tunicin, with thickness ranging from thin and delicate to transparent and gelatinous.

Ciona. Species: C. intestinalis. Binomial name. Ciona intestinalis. (Linnaeus, 1767) Ciona intestinalis (sometimes known by the common name of vase tunicate) is an ascidian (sea squirt), a tunicate with very soft tunic. Its Latin name literally means "pillar of intestines", referring to the fact that its body is a soft, translucent column-like ...
The predatory tunicate (Megalodicopia hians), also known as the ghostfish, [2] is a species of tunicate which lives anchored along deep-sea canyon walls and the seafloor. It is unique among other tunicates in that rather than being a filter feeder, it has adapted to life as an ambush predator. Its mouth-like siphon is quick to close whenever a ...
Larvacean. Larvaceans or appendicularians, class Appendicularia, are solitary, free-swimming tunicates found throughout the world's oceans. While larvaceans are filter feeders like most other tunicates, they keep their tadpole-like shape as adults, with the notochord running through the tail. They can be found in the pelagic zone, specifically ...
It is a filter feeder that eats by sucking in seawater and filtering out microorganisms. Pyura chilensis has some basic characteristics common to chordates, such as the notochord and a perforated pharynx. It is born male, becomes hermaphroditic at puberty, and reproduces by tossing clouds of sperm and eggs into the surrounding water.
Clavelina picta are invertebrate filter feeders that feed by inducing a current into the branchial cavity from the incurrent siphon, with the help of the endostyle using cilia. [3] Mucus glands in the endostyle secrete mucus used to filter through the incoming water and food particles. Once sorted, the mucus is moved by cilia to move food into ...
Tunica people. The Tunica people[1] are a group of linguistically and culturally related Native American tribes in the Mississippi River Valley, which include the Tunica (also spelled Tonica, Tonnica, and Thonnica); the Yazoo; the Koroa (Akoroa, Courouais); [2][3] and possibly the Tioux. [4] They first encountered Europeans in 1541 – members ...
