The stomach has usually eight folds and the anus opens halfway through the thorax. The larvae have ectodermal vesicles arranged dorsally and ventrally to the adhesive organs (Brunetti and Mastrototaro, 2017).
- Our colony, as described by Brunetti and Mastrototaro (2017), has a 6-lobed oral siphon, a simple languet, a plicated stomach with five folds, 15-16 rows of stigmata on the branchial sac (9-10 stigmata per half row), and an ovoid-shaped colony impregnated with sand. Moreover, the simple languet of the atrial aperture is characteristically situated anteriorly and separated from it. The thorax is as long as the abdomen and the anus, smooth-edged, opens at the level of the posterior part of the thorax (Ramos-Espla, 1991). All these mentioned characters, as well as features of the larvae, such as the arrangement of the ectodermal vesicles all around the visceral mass, confirm that the colony collected in Traste Bay belonged to the species A. tabarquense.
- This finding represents the first record of A. tabarquense in the South Adriatic Sea. Previous data on an A. tabarquense population were reported by Ponti and Mastrototaro (2006) for the North Adriatic Sea (Chioggia- Venice), describing a medium density of 33.9 ±7.9 colony/ m2. During the survey carried out in Traste Bay (November 2016), it was possible to observe many different colonies along the discharge pipe; it could thus be interesting to carry out further studies in order to better understand the distribution of this species and make a comparison with the above-mentioned study.
