Setae on the foreleg of a mayfly. Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of ...
Polychaete annelids (polychaeta literally meaning "many bristles") are named for their chaetae. In Polychaeta, chaetae are found as bundles on the parapodia , paired appendages on the side of the body. [ 1 ]
Scopulae, or scopula pads, are dense tufts of hair at the end of a spiders's legs.They are found mostly on hunting spiders, for example Salticidae and Sparassidae.Scopulae consist of microscopic hairs, known as setae, which are each covered in even smaller hairs called setules or "end feet", resulting in a large contact area.
The interactions between the gecko's feet and the climbing surface are stronger than simple surface area effects. On its feet, the gecko has many microscopic hairs, or setae (singular seta), arranged into lamellae that increase the Van der Waals forces - the distance-dependent attraction between atoms or molecules - between its feet and the surface.
Abdomen or opisthosoma: One of the two main body parts , located towards the posterior end; see also Abdomen § Other animals; Accessory claw: Modified setae at the tip of the tarsus in web-building spiders; used with tarsal claws to grip strands of the web [1]
There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla. For example, Protura, Diplura, and Collembola are often considered to be the three orders in the class Entognatha. This list should by no means be considered complete and authoritative and should be used carefully.
The abdomens of diplurans bear eversible vesicles, which seem to absorb moisture from the environment and help with the animal's water balance. [6] The body segments themselves may display several types of setae, or scales and setae. [7] Diplurans possess a characteristic pair of cerci projecting backwards from the last of the 11 abdominal ...
For example, verus is listed without the variants for Aloe vera or Galium verum. The second part of a binomial is often a person's name in the genitive case, ending -i (masculine) or -ae (feminine), such as Kaempfer's tody-tyrant, Hemitriccus kaempferi. The name may be converted into a Latinised form first, giving -ii and -iae instead.
