sea squirts squirt water it as simple as that
To survive
Camouflage I think
Sea squirts protect themselves primarily through their ability to rapidly expel water from their bodies, creating a strong jet that can help dislodge potential predators or threats. Additionally, they have a tough outer tunic made of a cellulose-like substance that provides physical protection. Some species also produce toxic compounds that can deter predators. By utilizing these strategies, sea squirts enhance their chances of survival in their marine environments.
check the encyclopedia,internet, etc.
Chordates such as the sea squirts and lancelets do not have a backbone that is why they are called vertebrate chordates.
Sea squirts (also known as cunjevoi) have a main diet of plankton
Sea squirts can glow due to bioluminescence, a chemical reaction within their bodies that produces light. This bioluminescence can serve various functions for sea squirts, such as attracting prey, deterring predators, or communicating with each other.
sea squirts protect themselves by squirting out a jet of water, hence the name, and they also have a tunic which is a layer of tissue covering them that can be thick and tough or thin and translucent, which protects them from predators. Lancelets spend most of their lives buried in the sand with only their heads sticking out, and have a hood that covers the mouth and sensory tentacles surrounding it thus protecting their bodies from predators.
They can't. That's why you don't put them in a tank with fish!
They draw in food
Land turtles defend themselves by going in their shells or finding holes to hide in. Sea turtles find places to hide and also go in their shell for protection.
