Why are they called Urochordates?
The name Urochordata is derived from the fact that the notochord is present in the tail (from the ancient Greek uron, tail).
What are Urochordates also called?
The Urochordata, sometimes known as the Tunicata, are commonly known as “sea squirts.” The body of an adult tunicate is quite simple, being essentially a sack with two siphons through which water enters and exits.

Urochordata is a subphylum of Chordata which includes the Tunicates and other classes such as Larvacea, Thaliacea etc. Tunicates or Urochordata are marine filter-feeding animals, found at all latitudes, and living mostly in shallow water. They are also known as “Sea Squirts”. An example of urochordata is Ascidia.
What are Urochordata characteristics?
Characteristics of Urochordata: Possesses a Notochord, a hollow nerve cord and a post anal tail. Body has more than two cell layers and includes tissues and organs. Has a U shaped gut. Body has no coelomic body cavity.
Why are urochordates called so?
Urochordates are called tunicates because of the leathery covering or tunic.
Does a sea squirt eat its own brain?
Being permanently attached to a home makes the sea squirt’s spinal cord and the neurons that control locomotion superfluous. Once the sea squirt becomes stationary, it literally eats its own brain.
What is the life cycle of a sea squirt?
The sea squirt spawns by releasing eggs and sperm into the water. After about three days, eggs develop into free-swimming, tadpole-like larvae. Larvae are fairly sophisticated: they have long tails, a primitive eye and backbone (called a notochord), a slender nerve cord, and a hollow, enlarged brain.
Why do sea squirts eat their own brains?
The sea squirt willingly gives up its nervous system, because it doesn’t come cheap — it uses up a huge amount of energy. There’s no free lunch, so it eats its own nervous system to save power. The implication is that brains are used to predict our actions, and in particular, are used for movement.
