“…However, a turtle being serviced at a cleaning station stretches its forelimbs and elevates its head and fore body. Thus, an attentive look may reveal that the turtle actually holds one of the characteristic postures assumed during cleaning interactions (Booth & Peters, 1972;Losey et al, 1994;Sazima et al, 2004; this study), and a brief inspection under the ledge or near the outcrop will likely disclose a cleaner shrimp and/or fish working on the turtle.…”

“…The posture assumed by the hawksbill turtle while on a cleaner shrimp station differed from the pose the green turtle assumes while being cleaned by small reef fishes (see Booth & Peters, 1972;Losey et al, 1994 for illustration and description), as the hawksbill rested on the bottom with its fore limbs stretched, the head and fore body elevated.…”

“…Cleaning symbiosis between two species of marine turtles and several species of reef fishes has been recorded both from the Pacific and the Atlantic (Booth & Peters, 1972;Smith, 1988;Losey et al, 1994). In this kind of interaction, the cleaner fishes obtain food, and the turtles get rid of the organisms' growth on their shells and/or soft body parts (Smith, 1988;Losey et al, 1994).…”

Hawksbill turtles visit moustached barbers: cleaning symbiosis between eretmochelys imbricata and the shrimp stenopus hispidus

At the oceanic island of Fernando de Noronha, off northeast Brazil, we recorded the hawksbill turtle (Eretmochelys imbricata) visiting cleaning stations tended by the barber pole shrimp (Stenopus hispidus). This seems to be the first record of cleaning symbiosis between marine turtles and shrimps. During their foraging on the reef flat, the turtles regularly visited and posed at the stations. The same stations were visited by a few species of reef fishes, which posed and were cleaned by the shrimps. We suggest that cleaning symbiosis between turtles and shrimps is widespread and went unrecognised due to the superficial resemblance between a resting turtle and a posing and cleaned one. Additionally, we submit a putative origin for the cleaning symbiosis between marine turtles and cleaner shrimps following a few simple behavioural steps. Key words: Marine turtle-cleaner shrimp association, cleaning symbiosis, origin of turtle-shrimp association, reef environment, Equatorial West Atlantic ResumoNas ilhas oceânicas de Fernando de Noronha, ao largo da costa Nordeste do Brasil, registramos tartarugas-de-pente (Eretmochelys imbricata) visitando estações de limpeza mantidas pelo camarão-palhaço (Stenopus hispidus). Este parece ser o primeiro registro de simbiose de limpeza entre tartarugas marinhas e camarões. Durante o seu forrageamento na planície recifal, as tartarugas visitavam e posavam nas estações regularmente. As mesmas estações eram visitadas por algumas espécies de peixes recifais, que aí posavam e eram limpas pelos camarões. Sugerimos aqui que a simbiose de limpeza entre tartarugas marinhas e camarões seja comum e difundida, porém passa despercebida devido à semelhança superficial entre uma tartaruga que esteja descansando e aquela posando e sendo limpa. Além disso, apresentamos uma origem putativa para a simbiose de limpeza entre tartarugas marinhas e camarões-limpadores, que segue etapas comportamentais relativamente simples.

“…Lessened swimming ability may be crucial under some circumstances, e.g., when male turtles are competing for a female (e.g., Booth & Peters, 1972;Perrine, 2003), or when they are attacked by sharks (e.g., Witzell, 1983;Perrine, 2003). Thus, the advantages for a remora attached on a sea turtle include taking a ride (an energy-saving behaviour), foraging, and mating opportunities.…”

An overview is presented for a poorly documented relationship between reef vertebrates in Southwest Atlantic: remoras (Echeneidae) associated with marine turtles. Two remora species (Echeneis naucrates and Remora remora) and four turtle species (Caretta caretta, Chelonia mydas, Eretmochelys imbricata, and Dermochelys coriacea) are here recorded in symbiotic associations in the SW Atlantic. Echeneis naucrates was recorded both on the coast and on oceanic islands, whereas R. remora was recorded only at oceanic islands and in the open sea. The remora-turtle association is usually regarded as an instance of phoresis (hitchhiking), albeit feeding by the fish is also involved in this symbiosis type. This association seems to be rare in SW Atlantic.Uma visão geral é apresentada sobre uma relação pouco documentada entre vertebrados recifais no Atlântico Sul Ocidental: rêmoras (Echeneidae) associadas a tartarugas marinhas. Duas espécies de rêmora ou pegador (Echeneis naucrates e Remora remora) e quatro de tartarugas (Caretta caretta, Chelonia mydas, Eretmochelys imbricata e Dermochelys coriacea) são aqui registradas em associações simbiônticas para o Atlântico Sul Ocidental. Echeneis naucrates foi registrada tanto na costa como em ilhas oceânicas, ao passo que R. remora foi registrada somente em ilhas oceânicas e região pelágica. A associação entre rêmoras e tartarugas é habitualmente considerada como forese, embora forrageamento, por parte das rêmoras, também esteja envolvido neste tipo de simbiose. Esta associação parece ser rara no Atlântico Sul Ocidental.

“…Mature male and female green sea turtles have been documented in coastal waters of Hawaii (Dizon and Balazs, 1982), Costa Rica (Carr et al, 1978), and Australia (Booth and Peters, 1972) prior to the onset of seasonal nesting. Satellite tracking data of male green sea turtles near Ascension Island have revealed temporary residency in the coastal waters of high-density nesting beaches (Hays et al, 2001).…”

Pre-nesting Movements of Leatherback Sea Turtles, Dermochelys coriacea, in the Western Atlantic

Understanding high-use areas for highly migratory species and their movements within these areas may provide insight into behaviors such as foraging and mating. In the Western Atlantic, the leatherback sea turtle, Dermochelys coriacea, has a broad geographic range extending from nesting beaches at low latitudes to foraging areas off the coast of Eastern Canada. Biotelemetry has revealed much about the movements and habitats of leatherbacks. However, the timing and location of leatherback mating behavior remains unclear. We conducted spatial analyses of the movements of reproductive female leatherbacks prior to their first seasonal nesting events. Using kernel density estimates, high-use areas for seven female turtles originally tagged in Canadian waters were revealed from 50% volume contours depicting pre-nesting movements (120 days prior to confirmed nesting events) and inferred mating behavior (45 days prior to confirmed nesting events). All individuals initially remained offshore within a relatively small range of latitude (10-15 • N) before transiting to and residing in coastal waters adjacent to nesting beaches in Colombia (n = 2), Trinidad (n = 3), Guyana (n = 1), and French Guiana (n = 1). Comparison of these movement patterns to those of mature male leatherbacks (n = 12) revealed similarities. Male and female residency within this offshore high-use area may be indicative of prey exploitation prior to the energetically-costly nesting season. While the offshore residency period of three males and one female extended into the interval in which mating is expected to occur, most males and females transited to coastal waters where they resided throughout this period. High-use areas determined through kernel density analysis support and corroborate previous telemetry work indicating that mature male leatherbacks exhibit seasonal residency adjacent nesting beaches for the early portion of the nesting season, presumably to exploit mating opportunities. Fine-scale analyses of fisheries interactions in both coastal and offshore waters and estimation of accompanying mortality rates is required to evaluate fishery threats to this population during the pre-nesting interval.
