The Red-throated Ascidian is a solitary species common in Sydney's coastal waters.
The Red-throated Ascidian has a thick, white or semi-transparent outer covering, and two prominent, red-rimmed siphons that it uses to filter plankton from the water. Usually the animal is so heavily covered in algae that only the red rims of its siphons can be seen.
The Red-throated Ascidian is found on rocky reefs to a depth of 3 m - 50 m.
