Functional effects of the hadal sea cucumber Elpidia atakama (Echinodermata: Holothuroidea, Elasipodida) reflect small-scale patterns of resource availability
Full text linkHolothuroidea represent the dominant benthic megafauna in hadal trenches (similar to 6,000-11,000 m), but little is known about their behaviour and functional role at such depths. Using a time-lapse camera at 8,074 m in the Peru-Chile Trench (SE Pacific Ocean), we provide the first in situ observations of locomotory activity for the elasipodid holothurian Elpidia atakama Belyaev in Shirshov Inst Oceanol 92: 326-367, (1971). Time-lapse sequences reveal 'run and mill' behaviour whereby bouts of feeding activity are interspersed by periods of locomotion. Over the total observation period (20 h 25 min), we observed a mean (+/- SD) locomotion speed of 7.0 +/- 5.7 BL h(-1), but this increased to 10.9 +/- 7.2 BL h(-1) during active relocation and reduced to 4.8 +/- 2.9 BL h(-1) during feeding. These observations show E. atakama translocates and processes sediment at rates comparable to shallower species despite extreme hydrostatic pressure and remoteness from surface-derived food

No full textTerrazoanthus onoi Reimer & Fujii, 2010 Figure 5, Table 1. Morphbank species collection 829714. Material examined. USNM 1134066, paratype. Diagnosis. Colonial Terrazoanthus with transitional (mesogleal–endodermal) and distinctly curved marginal musculature; marginal muscle to 922 Μm in length, composed of as many as 31 lacunae and 31 mesogleal pleats. Mesenterial arrangement macrocnemic. Columnar mesoglea adjacent siphonoglyph to 126 Μm width. Occurring at 1–35 m near Galapagos Islands, free-living. Coenenchyme and polyps colored reds or browns. Tentacles and mesenteries 32–40, oral disk calathiform when expanded, capitular ridges imperceptible due to extreme encrustations. Largest expanded polyps 20 mm long, 12 mm diameter. Description. Colony. Coenenchyme tan to dark brown and covers substratum as sheets; infiltrated with sediment. Not known to associate with other invertebrates. Colonies can cover areas> 1 m 2 (Reimer & Fujii 2010). Polyp. Capitular ridges inconspicuous (Morphbank 830701). Tentacles and oral disk bright red or red-brown; column and coenenchyme same color (Reimer & Fujii 2010). Polyps of 4–12 mm in diameter (expanded) rarely extend more than 20 mm from coenenchyme and cannot retract flush; body wall infiltrated with sediment (Reimer & Fujii 2010). Tentacles 32–40, dicyclic, and expand in length nearly the diameter of the calathiform oral disk (Reimer & Fujii 2010). FIGURE 5. Histology of Terrazoanthus onoi (10 Μm sections). Labeled features include actinopharynx (A), column wall (CW), dorsal directives (DD), encircling sinus (ES), fifth mesentery (5 th), oral disk (OD), peristome (P), siphonoglyph (S), tentacles (T), transitional (mesogleal–endodermal) marginal musculature (TMM), ventral directives (VD); measurements of capitular tissue width made at black arrow, measurements of column tissue width made at broken arrow, measurements of siphonoglyph tissue width made at gray arrow.

Cross-section of contracted polyp at level of actinopharynx showing dorsal directives and fifth mesenteries. D. Cross-section of contracted polyp at level of actinopharynx showing ventral directives and siphonoglyph. Internal Anatomy. In longitudinal section (Morphbank collection 829716), marginal musculature mesogleal distally, transitioning through distinct constriction and crescent-curve to endodermal proximally (Fig. 5 A). Approximately two-thirds length of marginal muscle enclosed within 25–31 (x = 28, n sections = 10) elliptical or lachrymiform lacunae that occupy full diameter of mesoglea distally, reducing in diameter prior to shifting toward endoderm proximally, with half of muscle attachment sites opening to endoderm and forming 22–31 (x = 27, n sections = 10) unbranched mesogleal pleats (Fig. 5 A). Length of marginal musculature (Fig. 5 A) 756–922 Μm (x = 858, n sections= 10), width at widest point (Fig. 5 A) 116–135 Μm (x = 124, n sections = 10). Diameter of largest lacuna enveloping muscle fibers (Fig. 5 A) 86–103 Μm (x = 94, n sections = 10). Large lacunae throughout ectoderm and outer three-quarters diameter of mesoglea resulting from dissolution of encrustations (Fig. 5 B). In the region of capitulum (proximal to terminus of marginal musculature; Fig. 5 A), ectoderm is 5–51 Μm (x = 24, n sections = 10), mesoglea 50–99 Μm (x = 72, n sections = 10) and endoderm 6–23 Μm (x = 11, n sections = 10) width. In cross section at actinopharynx (Morphbank collection 829715), mesenteries 30, fifth mesenteries macrocnemic (Fig. 5 C). Dorsal directives lachrymiform, similar to non-directive imperfect mesenteries (Fig. 5 C). Ventral directives (Fig. 5 D) supported by mesoglea 140–191 Μm (x = 166, n sections = 10) from column to siphonoglyph, 4–11 Μm (x = 8, n sections = 10) width, at retractor muscles 21–28 Μm (x = 24, n sections = 10) width, and homomorphic at column; similar to non-directive perfect mesenteries (Fig. 5 D). Actinopharynx without esophageal furrows (Fig. 5 C). Siphonoglyph distinct and U-shaped (Fig. 5 D); ectoderm is 23–62 Μm (x = 37, n sections = 10), mesoglea 15–28 Μm (x = 22, n sections = 10), and endoderm 7–16 Μm (x = 12, n sections = 10) width. Adjacent siphonoglyph (Fig. 5 D), column ectoderm is 23–55 Μm (x = 44, n sections = 10), mesoglea 96–126 Μm (x = 109, n sections = 10), and endoderm 17–23 Μm (x = 20, n sections = 10) width. Sparse mesogleal canals form an indistinct encircling sinus (Fig. 5 C, D). Lacunae resulting from dissolution of encrustations scattered in ectoderm and outer half width of mesoglea in column (Fig. 5 C, D). Cnidae. Tentacles, pharynx, and filament: basitrichs, mastigophores, holotrichs, spirocyst; column: holotrichs (see Reimer & Fujii 2010 for size and frequency). Distribution. Colonies free-living at 1–35 m near Galapagos Islands, Ecuador (Reimer & Fujii 2010). Remarks. Terrazoanthus onoi was erected to recognize differences from T. sinnigeri in polyp morphology (larger oral disk diameter and polyp height), colony size (larger colonies), color (red rather than brown), microhabitat (exposed surfaces rather than cryptic spaces), cnidae (identity and location), and mutations in nucleotide sequences (Reimer & Fujii 2010). Although the nucleotide sequences (ITS, but not COI or 16 S) used in the phylogenetic analyses of Reimer & Fujii (2010) appear to differentiate T. onoi from T. sinnigeri (see Figure 6 of Reimer & Fujii 2010), examination of nucleotide sequences culled from Genbank do not confirm a consistent difference. Nucleotide sequences of the most variable gene (and therefore most likely to detect independently evolving species) commonly used in Zoanthidea phylogenetics (ITS) cannot reliably distinguish between T. onoi and T. sinnigeri or E. patagonichus, and a single nucleotide mutation differentiates E. californicus (Table 1). It is possible that the nucleotide sequences that are identical (or nearly identical) between T. onoi and T. sinnigeri are actually all derived from T. onoi as Genbank accessions EU 333803 – EU 333810 are labeled T. sinnigeri in Genbank (last accessed on March 14, 2014) and T. onoi in Table 1 of Reimer & Fujii (2010). If the labeling of Table 1 in Reimer & Fujii (2010) is correct, than T. onoi and T. sinnigeri can be distinguished from each other with the use of ITS nucleotide sequences, but not T. onoi from E. patagonichus. Out of these species, T. onoi and E. patagonichus appear to be the most morphologically (and genetically) similar with many features indistinguishable (e.g., tentacle count and marginal muscle form) between the two species except for several characters that assess polyp size (e.g., the tissue thicknesses and marginal muscle dimensions) of the T. onoi paratype are 60–80 % of those of E. patagonichus specimens used in Swain (2010). It is unclear if these differences are sufficient to differentiate species or if the apparent differences between specimens would withstand broader sampling.Published as part of Swain, Timothy D. & Swain, Laura M., 2014, Molecular parataxonomy as taxon description: examples from recently named Zoanthidea (Cnidaria: Anthozoa) with revision based on serial histology of microanatomy, pp. 81-107 in Zootaxa 3796 (1) on pages 94-96, DOI: 10.11646/zootaxa.3796.1.4, http://zenodo.org/record/25114

Sequences: See Table 1. Description. Size: Polyps are approximately 2–8 mm in diameter when open, and rarely more than 10 mm in height. Colonies small, consisting of one polyp (unitary) to less than 50 polyps. Morphology: Terrazoanthus sinnigeri has dull brown, white, or clear oral disks and the outer surface of polyps is heavily encrusted with large particles, with polyps clear of the stolon. Stolons are also heavily encrusted, and approximately the width of polyp diameters. T. sinnigeri has 30 to 36 tentacles that are almost as long or sometimes longer as the diameter of the expanded oral disk (Figure 4). Tentacles often much more transparent than oral disks (when colored). Cnidae: Basitrichs and microbasic p-mastigophores (often difficult to distinguish from each other), holotrichs (large, medium), spirocysts (Table 2, Figure 9). Differential diagnosis. In the Galápagos, Terrazoanthus sinnigeri differs from Parazoanthus darwini and Antipathozoanthus hickmani by substrate preference (rock as opposed to sponges and anthipatharians, respectively), as well as from Terrazoanthus onoi sp. n. (above) by both color (brown, white or transparent as opposed to bright red) and microhabitat (under rocks and rubble as opposed to exposed rock surfaces). In addition, T. sinnigeri is smaller (oral disk diameter and polyp height) than congener T. onoi. T. sinnigeri colonies are stoloniferous and generally much smaller than colonies of T. onoi (Table 3). Terrazoanthus sinnigeri can be further distinguished from T. onoi by the presence of many types of nematocysts in the pharynx, unlike T. onoi, which only commonly possesses basitrichs and microbasic p-mastigophores with rare mediumsized holotrichs in the pharynx (Table 2). Terrazoanthus sinnigeri also has small holot- richs, while T. onoi does not (Table 2). Encrustations on the scapus of T. sinngeri are generally much larger than on T. onoi (compare Figures 3 and 4). Terrazoanthus sinnigeri is phylogenetically very closely related to T. onoi, but has different and unique ITS-rDNA (see T. onoi description; Figure 6). Similar to Terrazoanthus sinnigeri, there have been reports of other small zoanthids inhabiting cryptic habitats under coral rubble and rock from the Galápagos, Singapore and Japan (J.D. Reimer, T. Fujii, personal observation), but these zoanthids are clearly different in DNA sequence from all known Hydrozoanthidae and Parazoanthidae, and will be described elsewhere. Morphologically, these undescribed zoanthids look very similar to T. sinnigeri, but are often unitary (not colonial), are encrusted with very large pieces of sand, have very little coloring (usually lacking any color asides from around the oral opening) and have fewer tentacles (<26, usually 20–22; data not shown) than T. sinnigeri. Habitat and distribution. Specimens located at depths of 7 to over 27 meters at Floreana, Marchena, Darwin, North Seymour Islands, and Bainbridge Rocks, with other potential specimens observed at other islands. It is likely that this species is widely distributed throughout the Galápagos, and its distribution may extend into deeper waters as it was often found at the lowest depth searched during collection dives. Generally found on the underside of rocks, rubble, or dead shells, often in small cracks or crevices. Biology and associated species. Found under rocks and rubble, Terrazoanthus sinnigeri is often found nearby bryozoans and coralline algae, but appears to not be epizoic on any particular organism. Notes. In Reimer et al. (2008b) it was originally thought that Terrazoanthus sinnigeri (specimens 02-09, 03-560) was a different, white morphotype of T. onoi (mentioned in the paper and Hickman (2008) as Parazoanthus sp. G3) based on COI and mt 16S rDNA sequence data, but given the species’ divergent morphologies, cnidae, and ecologies, as well as different ITS-rDNA sequences, we describe them as closely related but distinct species. It is likely that these two sibling species have recently diverged from one another. Although speculative, it may be that Terrazoanthus sinnigeri ’s preferred habitat un- der rocks has resulted in its lack of bright pigmentation or occasional total lack of pigments compared to bright red T. onoi, which is found in areas more exposed to light, similar as to seen in subterranean invertebrates (e.g. Leys et al. 2003), and this should be investigated in the future.

It is possible that the nucleotide sequences that are identical (or nearly identical) between <i>T. sinnigeri</i> and <i>T. onoi</i> are actually all derived from <i>T. onoi</i> as Genbank accessions EU333803 – EU333810 are labeled <i>T. sinnigeri</i> in Genbank (last accessed on March 14, 2014) and <i>T. onoi</i> in Table 1 of Reimer & Fujii (2010). If the labeling of Table 1 in Reimer & Fujii (2010) is correct, than <i>T. sinnigeri</i> and <i>T. onoi</i> can be distinguished from each other with the use of ITS nucleotide sequences, but <i>T. sinnigeri</i> is differentiated by 5–6 nucleotide mutations from <i>E. californicus</i> (a level of variation in a hypervariable gene that is considered intraspecific in some zoanthid species; <i>e.g.</i>, <i>P. swiftii</i> or <i>Parazoanthus parasiticus</i> (Duchassaing de Fonbressin & Michelotti, 1860): Swain 2009b). Out of these species, <i>T. sinnigeri</i> and <i>E. californicus</i> appear to be the most morphologically similar with many features indistinguishable (<i>e.g.</i>, tentacle count and marginal muscle form) between the two species except for several characters that assess polyp size (<i>e.g.</i>, the tissue thicknesses and marginal muscle dimensions) of the <i>T. sinnigeri</i> paratype are 60–140% of those of <i>E. patagonichus</i> specimens used in Swain (2010). It is unclear if these differences are sufficient to differentiate species or if the apparent differences between specimens would withstand broader sampling.</p>Published as part of <i>Swain, Timothy D. & Swain, Laura M., 2014, Molecular parataxonomy as taxon description: examples from recently named Zoanthidea (Cnidaria: Anthozoa) with revision based on serial histology of microanatomy, pp. 81-107 in Zootaxa 3796 (1)</i> on pages 96-98, DOI: 10.11646/zootaxa.3796.1.4, <a href="http://zenodo.org/record/251140">http://zenodo.org/record/251140</a>
