- Most Ctenophores are transparent, they have no pigment.
- Most ctenophores are capable of bio-luminescence, which is visible in darkened conditions.
- They are made up of 2 layers: endoderm and ectoderm. (also a middle layer mesenchyme, but it's a weak built section.)
- Ctenophores are hermaphroditic, which means they have both male and female organs and produce egg and sperm.
