C65487809D32FFC2E3EFFA92F7FBF9D5.taxon	diagnosis	Diagnosis. Sponges, typically small, symmetrical, usually from deep water, with diagonal, radiating supporting processes and basal root adaptations for those living in soft sediments. Axial skeleton composed of monactinal or diactinal megascleres, from which radiating extra-axial tracts diverge to lateral processes. Microscleres include (an) isochelae, sigmas, forceps or micro (subtylo) styles (microspined, spear-shaped in a few cases). Considerable reduction to complete loss of the choanocytes being associated with an adaptation to carnivory (Hajdu & Vacelet, 2002).	en	Lundsten, Lonny, Reiswig, Henry M., Austin, William C.

C65487809D35FFC9E3EFFF5BF7F1FD80.taxon	description	Description. Holotype: an arborescent, dichotomously-branching sponge with bottle-brush arrangement of filaments 19.37 cm tall and 13 cm wide, but was likely wider as several branches were broken off before measuring (Fig. 2 A – E). Filaments are 1 – 9 mm in length (Fig. 4 A). At the base, the stalk is 7 mm wide and branches all taper to approximately 1 mm width distally. Attached to hard substrate via conic holdfast disk, 1.3 cm in width. Sponge is white in situ and in preserved state. Paratype: matching description above for holotype, 28 cm tall, 9 mm wide at conical base, 6 mm stalk width, and 2 mm branch tip width, tapering distally. Spicules. Large styles 1 (Fig. 3 A, Table 1), fusiform, straight, often with pointed end rounded, in axes of branches and stem: L 751 ± 46 µm (n = 53), W 25.5 ± 1.4 µm (n = 53). Large styles 2 (Fig. 3 B), fusiform, straight or slightly curved, in filaments and their inserts in branch axes: L 687 ± 69 µm (n = 103), W 17.5 ± 2.8 µm (n = 66). Large styles 3 (Fig. 3 C), fusiform, thick, strongly bent, mainly in basal cone: L 462.1 ± 79.7 µm (n = 85), W 39.97 ± 7.7 µm (n = 67). Microacanthotylostrongyle (Fig. 3 D) thin, rough, mostly curved, occurs in basal cone and sparsely throughout branch axes: L 98.1 ± 10.7 µm (n = 50), W 1.7 ± 0.4 µm (n = 50). Sigma (Fig. 3 E) robust, contort, without profile discontinuity near ends (not clearly sigmancistroid), occurs throughout specimen: L 22.9 ± 1.5 µm (n = 50). Palmate anisochelae (Fig. 3 F) foot with frontal tooth bearing two broad lateral flukes and distal medial spine extending toward spicule center, lateral wings short and never meet the frontal tooth; without spurs; occurs throughout the specimen: L 11.8 ± 0.5 µm (n = 50). Habitat and associated fauna. Asbestopluma monticola was first observed while conducting ROV dives at Davidson Seamount off central California in 2002. A single specimen was collected in 2006 while surveying Davidson Seamount once more. A dense population of A. monticola was observed there and they were noted as living attached to both the seafloor and, also, dead hexactinellid sponges. Since 2006, hundreds of additional observations of this species have been made. They are abundant in Monterey Canyon off northern California and central Oregon, a range of ~ 1000 km. They co-occur with numerous species of sponges (Staurocalyptus sp., Farrea sp., Chonelasma sp.), corals (Anthomastus ritteri Verrill, Paragorgia arborea Linnaeus, Keratosis sp., Corallium sp., Clavularia sp.), crustaceans (lithodid crabs, pandalid shrimps, amphipod), echinoderms (comatulid crinoids, Gorgonocephalus sp. ophiuroids, Hippasteria sp. asteroids), and vertebrates (Careproctus sp., egg case of Rajiformes, and Psychrolutes phrictus Stein & Bond). Small crustaceans like the pandalid shrimp were observed to be actively climbing upon and around the branches of A. monticola. The average depth of observation was 1236 m (± 211; n = 428). Oxygen concentration is low (0.85 ± 0.3 ml / L; n = 428) and temperature averages 3.18 ° C (± 0.54; n = 428). Small crustacean prey were observed in various states of decomposition on A. monticola (Fig. 4 A – D).	en	Lundsten, Lonny, Reiswig, Henry M., Austin, William C.

C65487809D35FFC9E3EFFF5BF7F1FD80.taxon	discussion	Remarks. Among the 42 known species of Asbestopluma, eight species branch. These are compared with A. monticola below. Asbestopluma monticola differs from A. formosa (Vacelet 2006), in that it lacks the characteristic embryo-containing branching enlargements, they differ in branching patterns — A. formosa has fan shapedbranches that divide dichotomously three or four times in a single plane with long, thin, and parallel terminal branches, and A. monticola also lacks microstrongyles. Asbestopluma monticola resembles A. desmophora (Kelly and Vacelet, 2011), however, it lacks desmas and sigmancistras and has bent fusiform styles in its basal cone. Asbestopluma monticola differs from A. bitrichela (Lopes et al., 2011) in a lack of desmas and anchorate / unguiforate anisochelae. This new species differs from A. delicata (Lopes et al., 2011) in the absence of microstrongyles and palmate isochelae. Asbestopluma monticola d iffers from A. magnifica (Lopes et al., 2011) in being much smaller (~ 50 % less) in total length, in having a single size class of anisochelae, and having a microtylostrongyle. When compared to A. furcata (Lundbeck, 1905), A. monticola has larger megascleres and only one size class of anisochelae (A. furcata has two size classes of anisochelae). Asbestopluma monticola is very similar to A. ramosa Koltun, however, A. ramosa has a flabelliform branching pattern, with vertical branches emanating from a single point and much thicker branches averaging 1.2 cm. Asbestopluma ramosa has larger spicules, especially when comparing anisochelae (Koltun, 1959; Stone et al., 2011). Asbestopluma ramosa also does not appear to have the robust, bent fusiform styles of A. monticola. Asbestopluma monticola superficially resembles A. rickettsi (described below), however, A. monticola differs in having only one size class of anisochelae. In situ, A. rickettsi is more transparent and much more delicate looking than A. monticola. A comparison of spicule data for all known Asbestopluma species through 2011 is published in Lopes et al. (2011).	en	Lundsten, Lonny, Reiswig, Henry M., Austin, William C. (2014): Four new species of Cladorhizidae (Porifera, Demospongiae, Poecilosclerida) from the Northeast Pacific.

Habitat and associated fauna. Asbestopluma rickettsi was observed and collected while surveying a chemosynthetic community in a low-oxygen basin off southern California, northwest of La Jolla. Twenty-one individuals were observed in an area of active fluid flow. The substrate was composed of outcrops of authigenic carbonate with a thin sediment veneer. Other organisms observed include vesicomyid clams, siboglinid tube worms, and mats of flocculent bacteria. Average depth of observation was 1031 m (± 48.5; n = 21), oxygen concentration was low at 0.33 ml / L (± 0.001; n = 21), and temperature averaged 3.93 ° C (± 0.02; n = 21). No evidence of crustacean prey capture was observed in A. rickettsi. This specimen was collected in an area with an active chemosynthetic community and was found to be utilizing methane-oxidizing bacteria as a food source (V. Orphan, California Institute of Technology, pers. comm.). It remains to be seen whether these bacteria are true symbionts, as has been demonstrated in one other species of Cladorhizidae.	en	Lundsten, Lonny, Reiswig, Henry M., Austin, William C.

C65487809D3AFFCEE3EFFAE5F692FC56.taxon	discussion	Remarks. Thirty-six other species of Cladorhiza are currently recognized (Lopes and Hajdu, 2013; van Soest et al., 2013) from sublittoral (110 m) to hadal (7295 m) depths. Cladorhiza caillieti differs from all other Cladorhiza in several ways including having different shape and two size classes of anisochelae, three different sigmas (including large flat-backed sigmas, smaller smooth sigmas, and even smaller thin, contort sigmas), and one size of sigmancistra. Cladorhiza caillieti differs from C. evae sp. nov. (described below) in spicule size classes and types. Cladorhiza caillieti has two size classes of anisochelae, the presence of a small, contort sigma, and nonfusiform small styles.	en	Lundsten, Lonny, Reiswig, Henry M., Austin, William C.

C65487809D3EFFD2E3EFFBFBF6F1FD56.taxon	description	Description. A stipitate sponge with filaments arranged in four or five discreet longitudinal rows, with valleys or depressions between rows (Fig. 10 A – E). All three specimens with partial rhizoids (Fig. 10 D); filaments long and fragile on specimens a (holotype) and b (paratype), shorter on the smaller and, presumably, younger, c (paratype). Holotype: 18.7 cm long, 3.2 mm wide at base, filaments up to 1.97 cm long. Paratypes: (b) 17.9 cm long, 3.4 mm wide at base, filaments up to 1.8 cm long, (c) 13.7 cm long, 1.7 mm wide at base, filaments up to 5.4 mm long. White in situ and in preserved state. Spicules.

Cladorhiza evae was collected from an inactive hydrothermal chimney that was covered in hydrothermally altered sediment. Galatheid and bythograeid crabs were observed in close proximity to C. evae on this inactive chimney. Nearby active chimneys had much richer communities of organisms with dense populations of siboglinid worms, galatheid and bythograeid crabs, and Thermarces sp., a zoarcid fish. Average depth of observation was 2373 m (± 154; n = 8), oxygen concentration was 1.54 ml / L (± 0.27; n = 8), and temperature averaged 2.02 ° C (± 0.23; n = 8). Numerous crustacean prey were observed in various states of decomposition on C. evae (Fig. 4 F – G).	en	Lundsten, Lonny, Reiswig, Henry M., Austin, William C.

C65487809D3EFFD2E3EFFBFBF6F1FD56.taxon	discussion	Remarks. Of the thirty-six other species of Cladorhiza currently recognized (Lopes and Hajdu, 2013; van Soest et al., 2013), C. evae differs from even the most similar in spicule size classes and suites. For example, C. evae differs from C. rectangularis (Ridley and Dendy, 1887) in having greater style width, larger sigmas of two size classes, and the presence of a sigmancistra. Cladorhiza linearis (Ridley and Dendy, 1887) differs from C. evae in having larger styles (to 3000 µm), small, non-contort sigmas of one size class, and larger anisochelae. Cladorhiza septemdentalis (Koltun, 1972) has smaller styles, larger anisochelae, and smaller sigmancistras than C. evae. Similarly, C. thompsoni (Topsent, 1909) has smaller styles, larger anisochelae, and no sigmancistras. Cladorhiza segonzaci (Vacelet, 2006) has smaller styles, sigmas, and sigmancistras. Cladorhiza evae differs from C. caillieti in the presence of a large (~ 2500 µm) size class of megascleres, a single size class of anisochelae, and no small, thin, contort sigmas.	en	Lundsten, Lonny, Reiswig, Henry M., Austin, William C.
