Numéro d’image : 11906634
| Lugworm faeces pile in the Red Sea. This species of tubeworm is unidentified but it may be the lug- worm,Arenicola,or a close relative. Faeces piles like these,of Arenicola,exposed at low tide,are well known by anglers who dig out the lugworm and use it as bait. The worm inhabits a U-shaped tube in the seabed. Found usually in the lower section of the tube,the worm filters sand by creating a water current through the tube and ingests sand particles. From the other leg of the tube,a spiral strand of faeces is excreted (as seen here). Through this water current the lugworm gets oxygen,and planktonic particles trapped in the sand act as food | |
