“…cichlid fishes, such as tilapia (Cichlidae), excavate circular nests and large burrows in lakes of southeastern Africa (Ribbink et al, 1981); male pufferfishes (Tetraodontidae) construct complex large geometric circular structures on the seabed probably to court females (Kawase et al, 2013); Atlantic sturgeon (Acipenseridae) leave feeding traces with the mouth and trails with the fins (Pearson et al, 2007); rays (Batoidea) excavate feeding depressions or pits by jetting water or by flapping their wings (Howard et al, 1977;Gregory et al, 1979;Martinell et al, 2001); male mudskippers (Oxudercinae) dig complex underwater burrows with air-filled egg chambers (Ishimatsu and Graham, 2011) and vertical shafts with turret-shaped openings (Takeda et al, 2011); gobiid fish (Gobiidae) may construct U-, W-and amphora-shaped burrows or branched burrow systems for dwelling and hiding (Atkinson et al, 1998;Gonzales et al, 2008;Minh Dinh et al, 2014) as well as large mounds of coral-rubble and sand over their burrows (Clark et al, 2000); tilefishes (Malacanthidae) excavate shafts and trenchs (Able et al, 1982;1987); red band-fishes (Cepolidae) dig vertical shafts with funnel-shaped apertures and occasional branching (Atkinson and Pullin, 1996); weeverfishes (Trachinidae) usually leave resting traces on the seafloor (Seilacher, 2007); male warmouths and bluegills (Centrarchidae) excavate semi-bowl-like depressions used as nests (Martin, 2013); sea lampreys (Petromyzontidae) build nesting structures by gathering pebbles into a circle or semicircle, and scooping out a central depression (Chamberlain, 1975); sticklebacks (Gasterosteidae) create shallow depressions filled with vegetation glued with bodily secretions for nesting (Hansell, 1984); among others.
