Taxonomy; Resources  Gallery  did you know that the Giant Barrel Sponge can live for over 2,000 years. This suggests that distinct species of giant barrel sponges must have existed prior to the most recent physical separation of the tropical Atlantic and the Indo-Pacific. Lines connecting haplotypes represent one base substitution between two haplotypes; additional crossbars indicate an additional base substitution each.

Nuclear DNA (nDNA) evolves independently from mitochondrial DNA (mtDNA); thus, congruent patterns across these markers support the existence of biological species (Goetze 2010; Padial et al. This renewal project would investigate the chemical ecology of Caribbean reef sponges, a group whose taxonomy … Three species have been described, with the species delineation mainly based on geographic distributions. Joseph Henry Press, Washington, USA, pp 83–108, Reece JS, Bowen BW, Larson A (2011) Long larval duration in moray eels (Muraenidae) ensures ocean-wide connectivity despite differences in adult niche breadth. The nuclear intron ATPsß provided much more genetic variation (157 segregating sites; π = 0.0767) than the mitochondrial genes (13 segregating sites; π = 0.0032). Resolving accurate species boundaries in such groups is important for the conservation of tropical marine ecosystems. A ninth group (group 4) consisted of a single sample from Taiwan. Sponges in the genus Xestospongia exist in many morphotypes and include the two giant barrel sponges Xestospongia muta, which is ubiquitous throughout coral reefs in the Caribbean, and Xestospongia testudinaria, which can be found throughout Indo-Pacific reef environments. 4. Xestospongia muta. However, present-day ocean currents and geographic barriers cannot explain why giant barrel sponges in the tropical Atlantic and the Indo-Pacific do not form monophyletic lineages, and why in each ocean basin multiple genetically isolated lineages exist in sympatry. 2016) using the Tamura–Nei model (Tamura and Nei 1993) with standard settings. Altogether, we identified at least eight potential giant barrel sponge species globally, yet the limitations of the markers make it impossible to exactly determine the number of species with the data presented in this study. Article  Barrel shaped, with thick walls. The congruent identification of a phylogenetic lineage by multiple unlinked genetic loci indicates that it is genetically isolated from other such lineages, and thus qualifies as a species, because only in separate species will the coalescent histories of the different markers agree (Avise and Ball 1990; Coyne and Orr 2004; Padial et al. They are considered the oldest multicellular animal lineage (van Soest et al. Pie chart size is relative to the number of individuals with that haplotype. BMC Evol Biol 11:176, van Soest RWM (1980) Marine sponges from Curaçao and other Caribbean localities. The giant barrel sponge has been called the "redwoodof the reef" because of its size and estimated lifespan of hundreds to a thousand or more years. However, if sponges do not form two distinct monophyletic groups in different ocean basins, it suggests that a species complex already existed prior to the ocean basins becoming separated. We found three potential giant barrel sponge species in the central Indo-Pacific (groups 1, 2, 3), three in the tropical Atlantic (groups 7, 8, 9), one in the western Indian Ocean (group 6) and one in the Red Sea (group 5). At present, giant barrel sponges occur in the western Indo-Pacific (including the Red Sea and western Indian Ocean), the central Indo-Pacific and the tropical Atlantic. However, these studies were done at small spatial scales, and, to the best of our knowledge, there has been no global phylogenetic study of any sponge taxon. An ABGD analysis on our nuclear data supported the groups 2, 3, 4, 5, 8 and 9 with recursive partitions at a prior maximal distance of 0.0046, while groups 1, 6 and 7 were not supported as separate groups (ESM S2). Economic Importance. Congruent patterns between mtDNA and nDNA markers of giant barrel sponges around the globe point to the existence of multiple genetically isolated taxa and support our hypothesis of the existence of additional species. Also, heterozygotes were only found with both alleles within the same nuclear group providing further support that different groups are reproductively isolated (ESM Fig. Also, some groups are only partly congruent, for example groups 4 and 5.

Re-analysis of the sample carrying the C3 haplotype from Lembeh Island showed that the sample was C2, and hence, this haplotype was wrongly identified (Swierts et al. 2005), mitochondrial variation was low (π = 0.0032). Trumpet fish represent a so-called ‘global ring species complex’, in which different lineages have come into contact after three to four million years of isolation and appear to be merging (Bowen et al. 2012).

Genetic markers have become increasingly important tools to identify divergent cryptic species and have forced the rejection of the long-believed assumption of cosmopolitan distribution of certain species (Boury-Esnault et al. Certain other groups were statistically supported, which is, particularly in combination with their sympatric occurrence, a strong indication for speciation.

Previously, the closure of the Isthmus of Panama, approximately 3 million yr ago (Keigwin 1978, was suggested as the final geographic separation between giant barrel sponges from the tropical Atlantic and the Indo-Pacific (Montalvo and Hill 2011; Swierts et al. 2013). The nuclear sequences provided much more information than the mitochondrial markers, but were mostly phylogenetically congruent with the mtDNA. It grows at depths from 10 meters down to 120 metres (390 ft), and can reach a diameter of 1.8 metres (6 feet). Giant barrel sponges are large and long-lived and have therefore been nicknamed ‘the redwoods of the reef’ (McMurray et al. Also, the inconsistencies of the placement of certain groups relative to other groups illustrate that the phylogenetic relationships between the groups cannot be completely resolved with the combination of markers used in this study. 2012), having evolved more than 500 million yr ago (Love et al. 2010) with the GTR model, which was the best fit model according to jModelTest2 (Guindon and Gascuel 2003; Darriba et al. S1). SPONGE SPECIES. Molecular studies on giant barrel sponges using these mtDNA and nDNA markers have revealed some interesting results. The kingdom is Animalia. In contrast, the giant barrel sponge, Xestospongia muta, showed evidence of limited larval exchange or connection between Pulley Ridge and the Dry Tortugas and no connectivity with the Florida Keys.

Three species of giant barrel sponge are currently recognized in two distinct geographic regions, the tropical Atlantic and the Indo-Pacific. For the ATP6 gene, we used the primers ATP6porF (5′-GTAGTCCAGGATAATTTAGG-3′) and ATP6porR (5′-GTTAATAGACAAAATACATAAGCCTG-3′), which amplified a product of 445 bp. DNA was extracted from sponge tissue using the DNeasy Blood and Tissue kit (Qiagen) following the manufacturer’s instructions.

A focus on wide-ranging studies within each marine phylum should therefore be a priority for the scientific community. 2013; Bell et al. It is, therefore, important to study and quantify the diversity of these systems and understand the evolutionary processes that have led to this diversity. Mean genetic distance for the nDNA was considerably higher than for the mtDNA. 1991). Also in the tropical Atlantic, McMurray et al. 2).

This information provides insight into genetic divergence among tropical reefs before physical barriers impeded gene flow between the Indo-Pacific and tropical Atlantic. 2013; Bell et al. These specimens may be over 100 years old, as the sponges grow only about 1.5 cm a year. 2010).

Samples that contained many double peaks may have represented mixtures of multiple sequences and were therefore cloned using the pGEM-T Easy kit (Promega Corporation) or the TOPO-TA cloning kit (Thermo Fisher Scientific), following the manufacturers’ protocols. The giant barrel sponge (Xestospongia muta) is the largest species of sponge found growing on Caribbean coral reefs. PubMed  While not all branches in the nDNA tree were statistically supported and some mtDNA haplotypes were shared between regions, we could identify multiple groups that potentially operate as reproductively isolated populations. General Organisation 7. Hooper, Gert Wörheide, Dirk Erpenbeck Giant kelp grow at an average rate of 11 inches (28 cm) a day but can grow 24 inches (61 cm) a day in ideal conditions. Giant barrel sponges from the tropical Atlantic and the Indo-Pacific sharing the same CO1 haplotype have both been related to an exterior morphology consisting of digitate structures (López-Legentil and Pawlik 2009; Swierts et al.

However, there is an inconsistency in their placement relative to the other groups, since they are most closely related to group 8 in the nDNA phylogenetic tree (Fig. Giant kelp grows faster than bamboo. Individuals were grouped based on a combination of mtDNA, nDNA and the geographic origin of the sample. This rules out the scenario that one species of giant barrel sponge developed into separate species complexes following geographic separation and instead suggests that multiple species of giant barrel sponges already existed prior to the physical separation of the Indo-Pacific and tropical Atlantic. Most studies that have focused on the distribution and evolution of marine species cover small spatial scales and become more useful when they are compared to more wide-ranging studies (Briggs and Bowen 2013; Cowman and Bellwood 2013a). This pattern may, however, be found in other tropical marine species, especially those with a long evolutionary history such as other globally distributed sponge groups. Not only are they the largest sponges on the reef, but they also are very long lived – up tp thousands of years. Classification 6. In the western Indian Ocean, we found five different haplotypes in 21 sponges that were spread over the haplotype network; three of these haplotypes were only present in this region. Giant Barrel Sponge has shades of gray color, brown, red brown or rose purple color. 3); a larger and more detailed rectangular phylogenetic tree is provided in the Electronic supplementary material, ESM, Fig. Sponges (Porifera) are an animal group with a relatively simple morphology and often pronounced morphological plasticity (Knowlton 2000). 2). 2013) due to the combined threat of climate change and anthropogenic stressors including pollution and overfishing (Hughes 1994; Pandolfi et al. The nuclear adenine triphosphate synthesis-β intron (ATPsβ) is very variable in giant barrel sponges, and because it is unlinked to the mtDNA, it serves as a good additional marker to identify potential species (Bentlage and Wörheide 2007; Swierts et al. 2008).
