This species probably evolved from Siphonodella ludmilae by the development of an additional rostral ridge on the left side of both the sinistral
and dextral Pa elements, and by the change of the symmetry class from II to III.
Cerci [+ or -] prominently enlarged, longer than anal segment, in-curving and specialized in various ways; mostly round to cylindrical in cross-section with an internobasal protuberance and occasionally with the apex laterally flattened and spatulate, bifid, trifid or deeply furcate; in certain genera asymmetrical cerci occur with the dextral cercus smaller than the sinistral
The Mundrabilla Fault is readily interpretable as a sinistral
transpressional fault formed during Proterozoic north-west directed Australia-wide compression.
Snail genera tend to be either dextral (right-coiling) or sinistral
(left-coiling) but the genus Satsuma contains both dextral and sinistral
species, reports Nature.
You can think about this distinction in Latin terms: sinistral
glabrata exhibits sinistral
cleavage and shell coiling, which is important to understand from a comparative standpoint.
vaginal aperture; vaginal canal composed of delicated non-sclerotised pipe.
Prominent among these outlaw bibliogenes--the sinistral
current of the accidental, the individual, meandering alongside orthodoxy's channelled dextral flow--would be Hans Hvass's Mammals of the World.
is not so bad nowadays as you get left-handed everything.
The northerly striking faults dip 50-70[degrees] eastward and are dextral, whereas the easterly striking faults dip 30-60[degrees] northward and are sinistral
Gonopodium asymmetrical, sinistral
, composed of anal rays 3, 4 and 5; tip with a small membranous hook (Fig.
The design's focal point is a pair of virtually indistinguishable human bodies hovering horizontally, locked in an ambitious embrace, with only background flames and clouds prompting viewers to differentiate a personification of energy or desire on their left, sinistral
side from one of reason on their right.
Even more startlingly asymmetrical are the flatfish with both eyes on one side of the head, such as sole (dextral in European waters, sinistral
in tropical and semi-tropical waters).
element shows widening but lacks denticles or nodes (Pl.
The Sig's separate slidestop and decocking controls have been married into one unit, and (pause here for a shout of joy from the sinistral
crowd), this dual-function lever is ambidextrous.
