“…[51][52][53][54] Remarkably, in both cases sensory neurons directly bind the inducer and trigger metamorphosis by secreting a GLW-family neuropeptide. [55,56] Strikingly, studies on vertebrate models provided evidence that intestinal microbiota is able to produce molecules structurally similar or identical to neurotransmitters, such as serotonin, acetylcholine, glutamate, and GABA, and thus has a potential to directly modulate the neuronal activity. [41,43,57,58] We propose that a systems biology approach based on deep transcriptomic and metabolomic analysis of microbes associated with Hydra, combined with a survey of existing complete genomic sequences of all major colonizers of Hydra (Fraune and Bosch, unpublished), may lead to identification of the bacteria-derived neuroactive molecules.…”

Here we evaluate our current understanding of the function of the nervous system in Hydra, a non-bilaterian animal which is among the first metazoans that contain neurons. We highlight growing evidence that the nervous system, with its rich repertoire of neuropeptides, is involved in controlling resident beneficial microbes. We also review observations that indicate that microbes affect the animal's behavior by directly interfering with neuronal receptors. These findings provide new insight into the original role of the nervous system, and suggest that it emerged to orchestrate multiple functions including host-microbiome interactions. The excitement of future research in the Hydra model now relies on uncovering the common rules and principles that govern the interaction between neurons and microbes and the extent to which such laws might apply to other and more complex organisms.

“…The settlement and metamorphosis of cnidarian larvae can be induced by marine biofilms (Müller 1969;Morse and Morse 1991;Leitz and Wagner 1992). Interestingly, these neuropeptides are involved in the metamorphosis of planula larvae into polyps in various cnidarians (Leitz et al 1994;Gajewski et al 1996;Takahashi et al 1997;Schmich et al 1998b;Iwao et al 2002;Katsukura et al 2003Katsukura et al , 2004. In addition, LWamide and RFamide peptides have been involved in the regulation of the creeping behavior of planula towards a light source (positive phototaxis), as the phototaxis of the planula was markedly promoted or suppressed by exogenously administered LWamide peptide or RFamide peptide, respectively (Katsukura et al 2004;Plickert and Schneider 2004).…”

Cnidarians and the evolutionary origin of the nervous system

Cnidarians are widely regarded as one of the first organisms in animal evolution possessing a nervous system. Conventional histological and electrophysiological studies have revealed a considerable degree of complexity of the cnidarian nervous system. Thanks to expressed sequence tags and genome projects and the availability of functional assay systems in cnidarians, this simple nervous system is now genetically accessible and becomes particularly valuable for understanding the origin and evolution of the genetic control mechanisms underlying its development. In the present review, the anatomical and physiological features of the cnidarian nervous system and the interesting parallels in neurodevelopmental mechanisms between Cnidaria and Bilateria are discussed.

“…During the annual mass spawning event at Aka Island, Okinawa, Japan (Hayashibara et al, 1993), gametes of Acropora tenuis were collected in situ using non-invasive plankton nets covering, but not touching, the sampled colony (Hatta et al, 2004). Eggs were ex situ fertilized, reared to larval stage following the protocol of Iwao et al (2002), and transported to Rotterdam Zoo (Petersen et al, in press b).…”

1. SECORE (SExual COral REproduction) Project is an initiative of public aquariums and research institutions to produce and exchange sexual coral recruits for the sustainable management of ex situ populations. Here we present the results of the initial three years (2002)(2003)(2004).2. Primary polyps (n=501) of corals (Acropora tenuis, Agaricia humilis, Favia fragum) were transported from Rotterdam Zoo to Cologne, Burgers', Hagenbeck and London Zoos, where development of juveniles was monitored for 10 months. All polyps were produced at Rotterdam Zoo from laboratory colonies (A. humilis, F. fragum), and from larvae generated from field collected gametes at Akajima, Okinawa, Japan (A. tenuis). Additionally, planulae of A. tenuis (n=1440) were transported from Rotterdam Zoo to Burgers' Zoo and to London Zoo to obtain primary polyps.3. Larval settlement (A. tenuis) was observed to be 3.00 AE 2.57% (mean AE SD; n=1480) in 2002 and 17.36 AE 6.01% (mean AE SD; n=1480) in 2003, significantly lower compared to settlement at Rotterdam Zoo (57.84 AE 11.01% in 2003; mean AE SD, n=1480). High post-transport survival rates of 95.18 AE 4.86% (mean AE SD; n=501) were observed in primary polyps of all species. 4. Juvenile survival (t=10 months; A. tenuis: 18.4-86.2%; A. humilis: 0-19.7%; F. fragum: 13.3-72.7%) differed significantly between institutions. Mean colony sizes (measured 10 months after transportation) were, in all cases, similar or higher to those reported from literature.
