pieterfA Perophora namei (Blue bell sea squirt). Under water you don't realy notice the beautiful colours. It's a colonial tunicate, forming clusters of small, bell-shaped individuals known as zooids and it is a filter feeder where each zooid possesses two siphons: an incurrent siphon for drawing in water and an excurrent siphon for expelling waste. Each zooid has a faint blueish colour which gives it it's common name.<br>
