Última The association of the goatfish mulloidichthys martinicus with the grunt haemulon chrysargyreum: an example of protective mimicry Biota Neotropica Krajewski,João Paulo; Bonaldo,Roberta Martini; Sazima,Cristina; Sazima,Ivan. A presumed example of protective mimicry between the yellow goatfish, Mulloidichthys martinicus (Mullidae) and the smallmouth grunt, Haemulon chrysargyreum (Haemulidae) is described from Fernando de Noronha Archipelago, NE Brazil. The goatfish and the grunt share a similar overall shape and colour pattern. We found that these two species regularly form mixed schools around reefs. Additionally, when chased small groups of yellow goatfish join schools of smallmouth grunts and behave like them. The colour and shape resemblances between the two species enable their mixed schooling, and enhance the protection against visually oriented predators for both of them. Thus, we suggest that the protective association herein reported for the goatfish and the grunt may...

The fish-jellyfish association is regarded as a temporary symbiosis believed to protect the fishes from predators. Here we report on juvenile scads (Trachurus lathami) associated with the jellyfish Chrysaora lactea, opportunistically preyed on by the grouper Mycteroperca acutirostris while the medusa was being damaged. The predation instances occurred when a couple of the filefish Stephanolepis hispidus approached the jellyfish to nibble on its umbrella. The feeding of the filefish caused a momentary disturbance of the defensive association, perceived and capitalised on by the watchful grouper, an opportunistic and versatile hunter. Before and after the disturbance, the protection offered to the young fish by the jellyfish showed to be effective, which...

Diurnal reef fishes compose the bulk of clients that seek cleaner fishes' services, but some nocturnal species that shelter at daytime also seek the cleaners. While doing so the nocturnal clients must leave their hiding places and thus they get exposed to potential diurnal predators. We report here on the cleaning interactions between a daytime cleaner wrasse (Thalassoma noronhanum) and a night time active client (Pempheris schomburgki) that usually remains sheltered at daytime. We recorded P. schomburgki leaving their shelter at daytime and heading towards T. noronhanum, whenever the cleaner swam by the shelter. Since T. noronhanum is able to tend temporary cleaning station near the safety of the shelters of its clients, P. schomburgki lessens a possible...

Ano: 2005 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252005000100008 Wolf in a sheep's clothes: juvenile coney (Cephalopholis fulva) as an aggressive mimic of the brown chromis (Chromis multilineata) Neotropical Ichthyology Sazima,Ivan; Krajewski,João Paulo; Bonaldo,Roberta Martini; Sazima,Cristina. We found yellowish juvenile coneys (Cephalopholis fulva) at Fernando de Noronha Archipelago, off Northeast Brazil, joining schools of similarly sized and coloured brown chromis (Chromis multilineata) when these latter closely approach the rocky reefs. Mingled within the mid-water hovering group of the plankton-feeding chromis, the piscivorous coney is able to approach unaware prey - an instance of aggressive mimicry. Three out of four coney individuals hunting under such disguise were successful in their attempts to prey on the otherwise wary rock-dwelling blenny (Malacoctenus species). This is the first instance of an epinepheline grouper mimicking a schooling and plankton-eating damselfish model in the West Atlantic.
