A Sea Pen is antype of coral. It resembles a quill.
It is also mistaken for feathers, whips or translucent worms.
Sea Pens are delicate marine animals.
They have hard, internal skeletons.
They are diverse; a few of them can glow in the dark.
Most sea pens grow to between 5 centimetres and 2 metres high.
A single sea pen like all coral can be viewed as a colony….
…or as an individual with many mouths.
