How do sea cucumbers defend themselves? Sea cucumbers can rapidly change the stiffness of their body, and scientists from Queen Mary University of London (QMUL) have discovered for the first time how they do it using data collected at ESRF. “This one is truly the first very complete and high-quality genome with which you can actually gather information in the future.”.

The darts are actually part of the animals respiratory system Sea cucumbers belong to the phylum Echinodermata, but their structure and function differ from other echinoderms. What do sea cucumbers eat? Some species of coral reef sea cucumbers defend themselves by expelling sticky cuvierian tubules to entangle potential predators. Sea cucumbers are part of a larger animal group called echinoderms, which also contains starfish and sea urchins. Some have specialized to feed on particles suspended in the water column, and have highly sensitive feeding apparatus. Sea cucumbers have tiny tube feet like sea stars and sea urchins. sea star. Other sea cukes have specialized sticky filaments surrounded by a viscous poison inside their bodies. Photo Credit: Flickr/Bernard DUPONT. How are these seemingly innocuous creatures able to protect themselves? Some species of coral reef sea cucumbers defend themselves by expelling sticky cuvierian tubules to entangle potential predators. When startled, these cucumbers may expel the tubules through a tear in the wall of the cloaca. How do sea cucumbers defend themselves? Sure enough, they saw a dramatic 10,000-fold up-regulated expression of genes from one cluster during the early stages of gut regeneration, indicating that they play a role in this process.
