Caption

Sea cucumber. Light micrograph of a transverse section through the mid-body region of a sea cucumber (Holothuria forskali). Sea cucumbers are marine invertebrates that have a leathery gherkin-shaped body surrounding this fluid-filled internal body cavity, called the coelom. The body wall is made of connective tissue (blue). Attached to the internal wall of the coelom are longitudinal bands (red, rounded, paired) that enable flexibility and contraction. The thin circular sections (red) within the coelom are the digestive and respiratory systems. Magnification: x3.5 when printed at 10 centimetres wide.
