Pectinaria aegyptia (Savigny, 1822)
You have to look very closely under water to discover the living tube of Pectinaria aegyptia, which is covered with many small stones.
A closer look at the tube already shows a small ,mosaic-shaped construction miracle, which the small worm, which does not fill the tube completely, has created.The small stones not only give the living tube a certain stability, they also protect the harmless worm from the eyes of hungry predators in the sea.
Unfortunately, we are not able to fill out the fact sheet in terms of scientifically sound information about the water depth and water temperature, because unfortunately these data are often not collected during initial determinations.
The photographer, Rafi Amar, from Italy was also able to provide the information of 1.5 meters to his night photo.
The body of the worm consists of a head, a cylindrical segmented body and a tail. Head consists of a prostomium (part in front of the mouth opening) and a peristomium (part around the mouth) and bears paired appendages (palps, antennae and cirrus).
Body short and divided into 3 regions; anterior body with palea-bearing segment, bristleless gill segments, and some bristle segments without ventral hooks; posterior body with dorsal bristles and ventral hooks; caudal region composed of bristleless, vestigial segments. Living in cone-shaped tubes of apparently systematically selected and finely cemented together sand grains and shill particles; the tubes are carried around like a quiver.
The sand in front of the mouth of the tube is loosened with the paleae located at the front end of the body and searched for small organisms and detritus with the help of tentacles. By contractions of the skin muscle tube, a powerful respiratory water flow is pumped through the tube from behind.
