After graduating from high school, he joined the Navy and completed over 26 years of service. He became interested in photography at the Aviation Fundamental School. As a member of VX6, he was assigned to an ice breaker. He produced a pictorial history of life on the ship. After arriving in Antarctica in 1956, he assisted in construction of a base. He photographed the items that the marine biologists removed from Weddell Sea.
During the 1957 trip, he did aerial mapping of the mountain ranges around McMurdo. The cameras were not designed for cold weather. The cameras operated satisfactorily after the lubricants were removed. A seismologist had him photograph seismology tests at the South Pole to determine the thickness of the ice cap. Another mission involved aerial mapping of crevasses on tractor trains routes. The equipment used in aerial mapping and the procedures are described.
During the 1958-59 season, he photographed the opening of the season—supplies and people arriving and winter crew leaving. The delivery of a new bulldozer to Byrd station resulted in some nice still photographs. The plane’s crew identified another mountain range while aerial mapping the Sentinel Mountains in 1959-1960. While at Byrd Station, he was advanced to chief photographer’s mate.
During the 1960-61 seasons, he did more aerial mapping. On one trip, a large deposit of coal was identified. In summary, Mr. Reimer comments on the interactions between scientists and the Navy personnel. After 3 years at NAS Norfolk, he was assigned chief in charge of the photo lab on USS America CVA66. After being made chief in charge of VDX6 photo division, he returned to Antarctica during Operation Deep Freeze 66. He had a similar assignment with Deep Freeze 68.

Tentacles and oral disk brown, white, or transparent; column same color as coenenchyme (Reimer & Fujii 2010). Polyps of 2–8 mm in diameter (expanded) rarely extend more than 10 mm from coenenchyme; column wall infiltrated with sediment (Reimer & Fujii 2010). Tentacles 30–36, dicyclic, and expand in length longer than diameter of the calathiform oral disk; (Reimer & Fujii 2010).</p> <p>Internal Anatomy. In longitudinal section (Morphbank collection 829713), marginal musculature mesogleal distally, transitioning through distinct constriction and crescent-curve to endodermal proximally (Fig. 6A). Approximately two-thirds length of marginal muscle enclosed within 25–39 (x = 32, n sections = 10) elliptical or lachrymiform lacunae that occupy full diameter of mesoglea distally, reducing diameter prior to shifting toward endoderm proximally, with half of muscle attachment sites opening to endoderm and forming 23–38 (x = 30, n sections = 10) unbranched mesogleal pleats (Fig. 6A). Length of marginal musculature (Fig. 6A) 808–1021 Μm (x = 903, n sections= 10), width at widest point (Fig. 6A) 114–181 Μm (x = 140, n sections = 10). Diameter of largest lacuna enveloping muscle fibers (Fig. 6A) 84–168 Μm (x = 106, n sections = 10). Large lacunae throughout ectoderm and outer half diameter of mesoglea resulting from dissolution of encrustations (Fig. 6B). In the region of capitulum (proximal to terminus of marginal musculature; Fig. 6A) ectoderm is 27–96 Μm (x = 56, n sections = 10), mesoglea 61–84 Μm (x = 75, n sections = 10) and endoderm is 10–21 Μm (x = 14, n sections = 10) width.</p> <p>In cross section at actinopharynx (Morphbank collection 829712), mesenteries 32, fifth mesenteries macrocnemic (Fig. 6C). Dorsal directives lachrymiform, similar to non-directive imperfect mesenteries (Fig. 6C). Ventral directives (Fig. 6D) supported by mesoglea 94–244 Μm (x = 175, n sections = 5) from column to siphonoglyph, 3–10 Μm (x = 7, n sections = 5) width, at retractor muscles 3–33 Μm (x = 25, n sections = 5) width, and homomorphic at column; similar to non-directive perfect mesenteries (Fig. 6D). Actinopharynx without esophageal furrows (Fig. 6C). Siphonoglyph distinct and U-shaped (Fig. 6D); ectoderm is 15–67 Μm (x = 34, n sections = 5), mesoglea 8–30 Μm (x = 21, n sections = 5), and endoderm 7–27 Μm (x = 17, n sections = 5) width. Adjacent siphonoglyph (Fig. 6D), column ectoderm is 43–94 Μm (x = 63, n sections = 5), mesoglea 62–141 Μm (x = 115, n sections = 5), and endoderm 19–34 Μm (x = 29, n sections = 5) width. Sparse mesogleal canals form an indistinct encircling sinus (Fig. 6C, D). Lacunae resulting from dissolution of encrustations scattered in ectoderm and outer third diameter of mesoglea in column (Fig. 6C, D).</p> <p>Cnidae. Tentacles and pharynx: basitrichs, mastigophores, holitrichs, spirocysts; filaments: mastigophores, holotrichs; column: holotrichs (see Reimer & Fujii 2010 for size and frequency).</p> <p> <b>Distribution.</b> Colonies free-living under rubble at 7–27 m near Galapagos Islands, Ecuador (Reimer & Fujii 2010).</p> <p> <b>Remarks.</b> <i>Terrazoanthus sinnigeri</i> was erected to recognize differences from <i>T. onoi</i> in polyp morphology (smaller oral disk diameter and polyp height), colony size (smaller colonies), color (brown rather than red), microhabitat (cryptic spaces rather than exposed surfaces), cnidae (identity and location), and mutations in nucleotide sequences (Reimer & Fujii 2010). Although the nucleotide sequences (ITS, but not COI or 16S) used in the phylogenetic analyses of Reimer & Fujii (2010) appear to differentiate <i>T. sinnigeri</i> from <i>T. onoi</i> (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 <i>T. sinnigeri</i> and <i>T. onoi or E. patagonichus,</i> and a single nucleotide mutation differentiates <i>E. californicus</i> (Table 1). 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>
Vitrumanthus Kise & Montenegro & Santos & Hoeksema & Ekins & Ise & Higashiji & Fernandez-Silva & Reimer 2022, GEN. NOV.
No full textGENUS VITRUMANTHUS GEN. NOV. (FIGS 6–8) Type species: Vitrumanthus schrieri sp. nov. by original designation. Zoobank registration: urn:lsid:zoobank.org:act: 00F773E4-4535-49F4-8CDA-30F569190BEF. Diagnosis: Parazoanthidae with obligate symbiotic r e l a t i o n s h i p w i t h m a s s i v e h e x a s t e r o p h o r a n a n d D e m o s p o n g i a e s p o n g e s. P r e s e r v e d p o l y p s 0.3–3.1 mm in length, 0.8–3.4 mm in diameter. Azooxanthellate. Cyclically transitional marginal musculature. Remarks: Vitrumanthus is distinguished from genus Churabana by its marginal musculature. In Vitrumanthus, cyclically transitional marginal musculature with several mesogleal lacunae was observed, while in Churabana cteniform endodermal marginal musculature with comb-like mesogleal pleats was seen. Molecular phylogenetic analyses clearly support the distinctiveness between Churabana and Vitrumanthus. In the 16S-rDNA region, Vitrumanthus has a unique deletion of 15 bp (positions 136–150 in our alignment). Etymology: The generic name is derived from the Latin word vitruma, glass, and Greek word anthos, flower, referring to the appearance of this genus. Gender masculine. The Japanese name is 'Ruri-sunaginchaku'.Published as part of Kise, Hiroki, Montenegro, Javier, Santos, Maria E.
