1. Additionally byssal threads have provided insight into the construction of artificial tendons 2. The entoliids did not / do not secrete a byssal thread. 3. Larvae likely settle anywhere they can attach byssal threads. 4. The byssal gland in these clams does not produce threads as in Pteriomorphia. 5. Gooseneck barnacles, byssal threads are able to overgrow all the other sessile organisms. 6. Here mussels can be the successful species, secured to the rock with their byssal threads. 7. This forms extremely tough, strong, elastic, byssal threads that secure the mussel to its substrate. 8. In the end stage of veliger development photosensitive eye spots and elongated foot with a byssal gland are formed. 9. Young mussels grow through the stockings, anchoring themselves to the ropes with their strong byssal threads ( beards ). 10. Once byssal threads have developed, the clams are moved to a secondary nursery system which contains sand as the substrate.
