Sea squirts are sessile tunicates that colonise

the world's oceans from the shelf to the deep sea.

With around 2000 species, they are the most species-rich group of tunicates.

Due to their ability to form a mantle and as internal micro-filters,

whereby they utilise the productivity of the free water body,

the sea squirts are one of the most successful animal groups.
