Or slightly shorter (in ossicles with extensively spaced arms); arms typically
Or slightly shorter (in ossicles with widely spaced arms); arms generally 0.1 mm Nimbolide NF-��B lengthy. Apophyses generally 4, slightly curved inward. Ventral ossicles (Figure 6I and Figure 7C,D) usually of the same shape as dorsal but slenderer and smaller in size, with arms usually 0.1 mm extended and apophyses slightly longer or equal in length with arms. Sometimes present flatten Peniagone-type ossicles, with four brief apophyses or sometime with no apophyses. Polian vesicle single. Genetic information. See Table S1. Etymology. The species is named in honor of Tatyana Sergeyevna Saveljeva (1902982), a Soviet zoologist and specialist on Holothuroidea. Distribution. The species is known only from the type locality inside the southern part of the Sea of Okhotsk. Remarks. Peniagone saveljevae resembles P. dubia and P. mus in external morphology inside the group on the northwest Pacific species, even so it differs by the absence of tube feet in the anteriormost third or fourth of your body and small velum. The tube feet inside the anterior half from the body is a common function in Peniagone occurring in Peniagone islandicaDiversity 2021, 13,13 ofDeichmann, P. azorica von Marenzeller, P. willemoesi (Th l), P. herouardi Gebruk, P. vedeli Hansen and also other species. This kind of morphology suggests far more epibenthic life style. Peniagone saveljevae also differs by the dorsal ossicles with four apophyses and curved arms as much as 0.15 mm long. three.6.

Genetic data. No genetic information is obtainable for examined specimens. Distribution. Sort locality is off southern Chile in the depth 2652 m (1450 fathoms), Challenger, St. 302. Other confirmed records are within the Eastern and Central Pacific, off Australia, and Antarctic (Figures 11 and 12). The new records are in the northwest Pacific, Kuril amchatka Trench area. Depth range 1360507 m. You can find also about 30 records published in GBIF.org [40] in the Eastern Pacific, off Australia and New Zealand identified by P.M. O’Loughlin, N. Davey and D. Pawson. Remarks. Peniagone vitrea at the moment has two junior synonyms: P. vitrea var. setosa Ludwig and P. setosa Ludwig. Hansen [24] has re-examined the kind series of P. vitrea and located pronounced variation in ossicle size among the forms of the synonymized species as well as the specimens in the Central and East Pacific reported by Clark [39] and from Galathea St. 716. The most significant ossicles were inside the Galathea specimen using the arms reaching 0.7 mm in length whereas within the kind specimens the arms had been 0.3.5 mm long. In our specimens from the northwest Pacific the arms inside the dorsal ossicles (Figure 8C) attained 0.4 mm, with two apophyses, rather straight, longer than arms and spinous. External morphology of these specimens (Figure 8A,B) corresponded nicely to that within the original description from the species. The physique was strongly elongated, velum lobe broad and short, tube feet bordering from posterior half to one particular third o.
