The average Sea Cucumber grows between 3.9 to 12”. Sea cucumbers has elongated, cylindrical bodies which are red, black, blue, green or brown in color. They have soft bodies even though they have some sort of skeleton below the surface of their body. The skeleton usually consists of plates and spines. These structures can be exposed and used against predators (sea cucumbers are not tasty meal when their bodies suddenly harden). Sea cucumbers use an interesting technique when they are faced with danger. They are able to expel internal organs along with toxic substance (called holothurin) towards the predator and all expelled/missing organs regenerated within 1.5 to 5 weeks.
