Worm Tubes on Oyster Shells 1 – Calcareous Tubes

Calcareous Worm Tubes on Oyster Shell (1)

Organisms that live on other creatures and inanimate objects are known as epibionts. Epibionts include various kinds of marine worms. Some worms attach to objects like seashells, while the mollusc is still alive and also when the shell is empty, by means of the tube in which they live. These tubes are made of diverse materials such as sand grains, shell fragments, or particles of mud stuck together with mucus or other secretions. Other tubes are manufactured entirely by the worm – such as the calcareous or chalky tubes shown here on an oyster shell (Ostrea edulis Linnaeus). The tube shapes are characteristic for different species of worm. The tubes illustrated here have been made by worms like Pomatoceros spp.

I have a background in ecological studies in both the museum and the research laboratory. I'm passionate about the natural world right on my doorstep and enthusiastic about capturing what I see through photography, wanting to open the eyes of everyone to the beauty and fascination of nature. I am author of Jessica's Nature Blog [https://natureinfocus.wordpress.com]. I have also extensively researched macroscopic variations in oyster and other edible marine mollusc shells from archaeological excavations as a means of understanding past exploitation of marine shellfish resources. I am an archaeo-malacological consultant through Oysters etc. where I am publishing summaries of my shell research and other oyster related topics [Oysters etc. at https://oystersetcetera.wordpress.com]. Photographic Salmagundi [https://photosalmagundi.wordpress.com] is a showcase of photographs and digital art on all sorts of subjects - not just natural history. P.S. The current profile picture was taken in 2015 at Whiteford Sands in Gower where I am kneeling to take pictures of an ancient buried tree trunk emerging from the peat for the first time after submersion by rising sea levels about 6000 years ago.
