Polyplacophora (Mollusca) from reef ecosystems and associations with macroalgae on the Coast of Alagoas, Northeastern Brazil

Estado atual de conhecimento das principais características dos Moluscos / Current state of knowledge of the main characteristics of mollusks

“…Os poliplacóforos possuem rádula, manto espesso, pé ventral amplo, corpo achatado e alongado provido de concha dorsal dividida em oitos placas imbricadas e articuladas, olhos e tentáculos ausentes (OKUSU et al;2003;LOZOUET, 2006;CORREIA et al, 2015). Há evidência de achados fósseis de espécies com ausência de concha como a Wiwaxia corrugata (Mateus, 1899) (MORRIS; CANON, 2007).…”

“LOOKING FOR A HOME”: THE ECOLOGICAL ASSOCIATION BETWEEN THE CHITONS Ischnochiton striolatus (GRAY, 1828) AND OTHER MOLLUSCS SPECIES

“…Such interactions are difficult to measure and define because of the evolutionary context and environmental conditions in which organisms live (Lang & "LOOKING FOR A HOME": THE ECOLOGICAL ASSOCIATION BETWEEN THE CHITONS Ischnochiton striolatus (GRAY, 1828) AND OTHER MOLLUSCS SPECIES Benbow, 2013). The Mollusca phylum participate in several interspecific ecological associations, such as: gastropods with cnidarians (Robertson, 1980;Mercier & Hemel, 2008) and with bryozoans (Morris et al, 1991); bivalves with echinoderms Ishikawa & Hamamura, 2016;, with annelids (Silina & Zhukova, 2012) and with crustaceans (Gonzalez & Jaramillo, 1991;Nara;Akiyama & Itane, 2008); and polyplacophora with macroalgae (Correia;Coelho & Sovierzoski, 2015), with rocks (Kaas & Van Belle, 1990;Van Belle & Strack, 2006), with cnidarians (Tod et al, 2009 and with crustaceans (Berthegar, 1968).…”
