For instance, the crinoid Antedon
mediterranea appears unable to autotomize internal organs.
mediterranea were observed for the first time of the dredge study in November.
Bacteria were also isolated from the surfaces of a number of sponges (Haliclona viscosa, Halichondria bowerbanki, Myxilla incrustans, Halichondria panacea, and Pachymatisma johnstonia), a featherstar (Antedon
bifida), and two compound tunicates (Botryllus schlosseri and an unidentified specie).
The colorful, delicate feather stars, or articulated crinoids (Antedon
, Leptometra), are among the most beautiful sights on the night reefscape.
By using this approach, members of the Bmp, TGF-beta, and Hox gene families were found to be associated with arm regeneration in the crinoids Antedon
bifida and Antedon
mediterranea (Thorndyke et al., 2001; Patruno et al., 2002), and eventually a novel Bmp member was identified in regenerating arms of the brittle star Amphiura filiformis (Bannister et al., 2005, 2008).
For example, after evisceration in the crinoid Antedon
mediterranea the anlage of the intestine appears by day 3, while differentiation of the enterocytes begins by day 5 (Mozzi et al, 2006).
Similarly, it has recently been proposed that the coelomic epithelium plays a crucial role in gut regeneration in the crinoid Antedon
Microscopic anatomy and functional significance of the muscle-ligament-skeleton system in the arm of comatulids (Antedon

mediterranea (Echinodermata, Crinoidea).
