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.
