Abstract: -The whalesucker Remora australis (Echeneidae) is an oceanic diskfish found attached to cetaceans only and its habits are therefore poorly known. At the Fernando de Noronha Archipelago, off North-eastern Brazil, spinner dolphins Stenella longirostris (Delphinidae) regularly congregate in large groups in a shallow bay, which allows for underwater observations of their behaviour and their fish associates. In the course of a broader study of this elusive diskfish, we had the opportunity to made multiple records o… Show more

“…It is known that spinner dolphins occur mainly in areas of high water transparency (Perrin 2002). Moreover, earlier studies showed that the daily routine of spinner dolphins, both in other regions (Norris et al 1994 a ) and in Fernando de Noronha (Sazima et al 2003; Silva Jr. et al 2004, 2005), involves nocturnal feeding and daytime reproduction and rest. During the dry season the increased length of the light phase may favor the longer period spent by the dolphins in the area, allowing them to make better use of the temporal niche for reproductive activities and other behaviors.…”

“…The rate of regression of the bite mark reported herein, a maximum of 150 d, is expected to be considerably greater than the minimum time for healing since NZ118 was not sighted in the interim between having an open wound and a completely healed scar. Shorter time frames for regression can also be expected based on the healing rate (74 d) of a cookie cutter shark bite mark on a whalesucker (Remora australis) (Silva & Sazima, 2003). Equally, Wiseman (2008) provided a sequence of photographs of a Bryde's whale, from which a regression rate of a maximum of 98 d can be calculated for a bite mark to progress from open to scar.…”

“…It has been suggested that attaching to mobile hosts benefits the remoras by reducing metabolic demands for swimming (Muir and Buckley, 1967), offering opportunistic feeding (Strasburg, 1962) or increasing the chance of finding mates (Silva and Sazima, 2003). Remoras have been known to strongly attach to sharks (Ritter, 2002;Ritter and Brunnschweiler, 2003), rays (Williams et al, 2003), other pelagic fish (Williams et al, 2003), sea turtles (Sazima and Grossman, 2006), dolphins (Weihs et al, 2007), divers (Silva and Sazima, 2003), buoys (Cressey and Lachner, 1970), ship hulls (Cressey and Lachner, 1970) and concrete (Strasburg, 1962). This variety of hosts moves at many different speeds and have body surfaces that span a broad spectrum of geometries and topologies (Stote et al, 2014).…”
