“…Using estimates of Nei's genetic distance based on isozyme data, Solé-Cava & Thorpe (1986) concluded that the two species of Suberites associated with bivalve shells and S. pagurorum Sole-Cava & Thorpe, 1986, associated with P. bernhardus diverged 7-8 MYA. Sandford & Kelly-Borges (1997) found evidence of convergent evolution between sponge associates of hermit crabs, that is Pseudospongosorites suberitoides (Sandford, 1995) and Suberites Nardo, 1833, based on similarities in morphological features. As with other epibiont groups (such as Cnidaria and Bryozoa), hermit crab shells provided a hard surface for the sponges to settle upon; the association between sponges and hermit crabs was then reinforced by the benefits of increased food availability and reduced risk of permanent burial (Williams & McDermott, 2004).…”

Although epibiosis in Crustacea has been well known for a long time, only during recent decades these associations have been considered from various aspects: physiological, evolutionary, ecological, and so forth. Current research has begun to study in detail the processes concerning epibiosis and their effects on the biology of the organisms involved. The aim of this study is to present a general overview of epibiosis in Crustacea, including its ecological importance, adaptations to epibiotic life, specificity of the associations, and other characteristics of epibiont-basibiont interactions. RESUMENA pesar de que la epibiosis en crustáceos es bien conocida desde hace tiempo, sólo durante las últimas décadas las asociaciones ha sido consideradas desde variados aspectos: fisiológico, evolutivo, ecológico, etc. Desde entonces, se han empezado a estudiar en detalle los procesos concernientes a la epibiosis and sus efectos en la biología de los organismos implicados en este tipo de relación. El propósito del presente estudio es presentar una visión general de la epibiosis en los crustáceos, considerando su importancia ecológica, las adaptaciones a la vida epibiótica, la especificidad de las asociaciones, y otras características de las variadas interacciones epibionte-basibionte. 1 )

“…In such cases, the symbiont may not only produce a very thick encrustation which strengthens the shell, but can also grow outwards from the shell aperture in the form of a helicospiral tube, mimicking the shape of the gastropod shell and providing an enlarged chamber for the hermit crab to occupy (Taylor, 1996). Modern examples of this type of symbiont are known among coralline red algae (Zuschin and Piller, 1997), sponges (Sandford and Kelly-Borges, 1997), hydrozoans (Cairns and Barnard, 1984) and bryozoans (Taylor, 1994) (Fig. 11).…”

“…It was hypothesized that any differences found could be of taxonomic or evolutionary importance or usefulness. (CCBD 113-93, 117-93, and 262-1997) collected from the intertidal zone (Dog Island, Florida, 0.3-1 m, originally occupied by Pagurus impressus), and the other (USNM 32719), collected off South Carolina (8 August 1981), hermit crab occupant unknown (Sandford and Kelly-Borges, 1997). …”

The siliceous skeletons of six hexactinellids and demosponges were compared using a series of physical and chemical tests. The sponges were two hermit-crab sponges (Class Demospongiae, family Suberitidae), one from Scotland, Suberites domuncula, and the other, Pseudospongosorites suberitoides, from the Gulf of Mexico, and four hexactinellids, Hyalonema sp., Euplectella aspergillum, Rhabdocalyptus dawsoni, and Aphrocallistes vastus. The operating hypothesis was that differences in the amorphous hydrated silica skeletons in Demosponges and Hexactinellids might prove taxonomically useful. Physical properties studied included SEM, glass density, glass transition temperature (Tg), TG/DTA to determine water content, and FTIR spectra. Chemical determinations were made using energy dispersive X-ray fluorescence (EDXRF). Spicular skeletal material is deposited in concentric layers around the axial canal. With the exception of differences at several bands in the IR spectra, the siliceous skeletons in demosponges and hexactinellids are largely indistinguishable. Density was similar in all sponges (range 2.03-2.13 g/cc) and similar to the density of opal (SiO2 x 1.5H2O) (mean = 2.09 g/cc). IR spectra were similar, with prominent absorption bands at 460-470, 800, and 1,090-1,100 cm(-1) (due to different vibrational modes of Si-O-Si linkages) and at 1,650 and 3,450-3,560 cm(-1) (due to water). The skeletons of all six showed similar spectra to that of silica gel both before and after heating to 1,200 degrees C. Water comprised 10-14% of the skeleton by weight, slightly higher in the demosponges. Average spicule chemical composition was 85.2% SiO2, 12.3% water, and 2.5% other elements (mainly S, Al, K, Ca, and Na). The percent amounts of Si did not differ significantly between the demosponges and the hexactinellids.
