What do sea squirts look like?
Sea squirts, also known as tunicates, come in different shapes and sizes. They can be cylindrical, vase-shaped, or globular, with a tough outer coat made of a substance called tunicin. They often have two siphons, one to draw in water for feeding and the other to expel waste.
Are sea squirts classified as a phylum echinodermata?
No; Echinodermata is the phylum of starfish and sea cucumbers. Sea squirts actually belong to the phylum Chordata, just like all vertebrates, including us! Their larva has a structure that's considered the early version of a backbone, explaining why they're classified that way; they're related to vertebrates.
Which of the following findings led to the conclusion that sea squirts are more closely related to vertebrates than scientists had previously thought?
Probably the discovery of the tadpole larva and the Larvacea group. They resemble the lancelet something awful. But the neoteny theory is discarded now - it´s thought some lancelets took on a sessile lifestyle and others gave rise to the vertebrates. And some just stayed lancelets, of course ;)
How do sea squirts and lancelets protect themselves?
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.
