If a tunicate's pharyngeal gill slits were suddenly blocked, the animal would have trouble respiring and feeding.
What is pharyngeal slits ?
Pharyngeal slits, or openings between the pharynx, or throat, and the outside world, are the third characteristic of chordates. They have undergone substantial change throughout the course of evolution. Early chordates use these pores to filter food particles out of the water.
When it comes to possessing a tail and pharyngeal slits at some point in their lives, humans are no different from other chordates. Early in development, the human embryo has pharyngeal slits and a tail, but both are lost as the adult grows.
What is tunicate?
The marine invertebrate species known as tunicates are a component of the Tunicata subphylum. It is a member of the phylum Chordata, which includes all organisms with notochords and dorsal nerve cords. Even though the subphylum is no longer known by that name, these species are nevertheless occasionally referred to as "urocordates".
