The phrase "a seta" is not correct in standard written English.
It may be an attempt to use a term from another language or a misspelling, but it does not convey a clear meaning in English.
Example: "I found a seta on the ground." (This would be incorrect unless "seta" is defined in context.)
Alternatives: "a mushroom" or "a fungus."
And a seta will stick to a surface most firmly if it is first pushed into the surface and then pulled along it by a few millionths of a metre.
A cyprid destined to become a female seeks out a host, such as a crab, and attaches where the cuticle is thin, usually on a gill or at the base of a seta.
Setae are, in other words, even stickier than expected giving the gecko a surprisingly large safety margin.In this section Infertility and inheritance Quality counts Climbing the walls Lodestones on the loose ReprintsThe researchers found that the way in which geckos place their feet on a surface may be crucial to a seta's stickiness.
After fertilisation, the immature sporophyte within the archegonium develops three distinct regions: (1) a foot, which both anchors the sporophyte in place and receives nutrients from its "mother" plant, (2) a spherical or ellipsoidal capsule, inside which the spores will be produced for dispersing to new locations, and (3) a seta (stalk) which lies between the other two regions and connects them.
In crayfish the resilin formed a ring around the base of a seta, but in crabs had a more elaborate structure with two arms forming the pivots in a socket on the flagellum, and a broader region extending into the shaft of the seta.
The morphology of these scales falls into two distinct categories: those on the coxae of the prosomal appendages are conical, do not extend far over the underlying limb podomere, and bear a seta located in a notch beneath the apex of the cone (Figs. 6c and 23b, d); those on the opisthosoma bear setal bases that project from beneath the scale where it overlaps the tergite below (Fig. 23e).
Within Chorioptes, the mites detected in moose in Sweden were found to have more or less quadrangular opisthosomal lobes, and outer opisthosomal setae ae (seta 1) distinctly shorter than setae l4, l5 (seta 2) and d5, which arose as a group close to each other.
2nd endopod article: ventral margin with 3 long terminal setae with short spines, dorsal margin with stout a-, b-, c-, and-setaeae, 1 slender seta proximal to a-seta; medial side with 7 "cleaning" setae, and 1 long g-seta distal to base of d-seta; lateral side with no e-seta between b- and c- setae, and 1 long f-seta between c- and d- setae.
The mites from the moose differed from C. mydaus by a shorter seta ae, which was 85 μm on average compared to 100 μm in C. mydaus [ 18].
This allowed the evolution as one of the crustacean novelties, a setae-bearing endite, the proximal endite, which occurred medially just below the limb stem [ 11- 16].
Legs incompletely preserved except for right fore leg about 7.17 mm long, with femur about 1.5 times as long as tibia, tibia thin basal, with a long seta or a few ventral setae at apex, basitarsus slightly shorter than tibia, claws almost straight.
