Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
Close-up of the underside of a gecko's foot as it walks on vertical glass Common house geckos mating on a vertical glass window and showing lamellae under the feet. The pads on a gecko's feet are small hair-like processes that play a role in the animal's ability to cling to vertical surfaces.
Microfauna (from Ancient Greek mikros 'small' and from Latin fauna 'animal') are microscopic animals and organisms that exhibit animal-like qualities and have body sizes that are usually <0.1mm. [ 1 ] [ 2 ] Microfauna are represented in the animal kingdom (e.g. nematodes , small arthropods ) and the protist kingdom (i.e. protozoans ).
An example would be a vertebrate with an alcohol-preserved skin and viscera, a cleared and stained head, the post-cranial dried skeleton, histological, glass slides of various organs, and frozen tissue samples. This specimen could also be a voucher for a publication, or photographs and audiotape.
Its function is to mix and transport food from the lumen into the hindgut through contraction. Many species of syntrophic bacteria, archaea, and fungi are present in the lumen. These different digestive regions have varying pH to support specific enzymatic activities and microbial populations.

The Nematocera (the name meaning "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae.This group is paraphyletic and contains all flies except for species from suborder Brachycera [4] (the name meaning "short-horns"), which includes more commonly known species such as the housefly or the common fruit fly.
The Zoraptera are currently divided into two families, four subfamilies, nine genera and a total of 51 species, some of which have not been yet described. [12] [13] [14] There are eleven extinct species known as of 2017, many of the fossil species are known from Burmese amber. [15] Family Zorotypidae Silvestri, 1913. Subfamily Zorotypinae ...
