Despite this difference in web architecture, the breaking strength and extensibility of Latrodectus dragline silk are equal to or higher than those of true orb-weaving spiders [43] [45].
As descendants of orb-web weaving ancestors [ 44], black widows possess all the gland types of true orb-web spiders despite building three-dimensional cobwebs [ 45].
In addition to accounting for over 90% of spider species, the Araneomorphae, also known as the "true spiders", include orb-web spiders, the cursorial wolf spiders, and jumping spiders, as well as the only known herbivorous spider, Bagheera kiplingi.
A somber mood fell over the disappointed Orb camp, but true to their old-school approach, the connections said they would check on the horse first before they could even contemplate his next destination.
A gowned female figure floats on the brick facade in Lisa Yorio's "Walking With Ghosts: True Encounters of the Paranormal," and an orb hovers on the red-carpeted stairs in Corinne May Botz's "Haunted Houses".
In contrast, within the suborder Araneomorphae (so called true spiders), the Araneoidea (a clade of orb web weaving spiders and their kin) possess seven morphologically differentiated silk gland types that each synthesizes a task-specific fiber or glue (Vollrath and Selden 2007; Foelix 2010).
This caused an unworldly sparking and steaming, and — at precisely the moment the World-Father's body crashed to the Shag Carpet of the Celestial Den — a new being emerged from the orb: the most perfect of all, true son and heir of the World-Father.
That the Hancock and Phipps families could be this close and still compete against each other, as they last did when Claiborne's Departing challenged Phipps's Orb in the Preakness three weeks ago, is hard evidence of the true sporting aspects of thoroughbred breeding.
Precise mechanisms of Nephila dispersal are not documented; however, orb weavers generally disperse by wind travel termed 'ballooning' [ 5], which is likely also true for Nephila [ 20].
1 For all simulations, we set the true treatment effects of A versus P and B versus P, expressed as OR to ORA = 1.40 and ORB = 1.20.
