Tunisian bryozoans are poorly studied, their knowledge was based especially on some old works. An updated list counting 201 was conducted by d’Hondt & Mascarell (2004) by adding to the previous literature data a total of 22 species. More recently, some studies carried out in northern Tunisia by Ayari et al. (2008; 2012a; 2012b; 2014 and 2022), resulted in the identification of 72 bryozoan species, among which 26 species were newly added to the Tunisian fauna.
