2. Spirographis

These tubeworms are kind of modest because they build their homes out of mucus and silt (even though they seemingly have an unlimited budget to spend on their wardrobes).

7. Tunicates

Not to be confused with tourniquets! These guys are casually known as "sea squirts," which is pretty great. Unfortunately, they are pretty useless during emergencies.
