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.
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 ).
In botany, "seta" refers to the stalk supporting the capsule of a moss or liverwort (both closely related in a clade called "Setaphyta"), and supplying it with nutrients. The seta is part of the sporophyte and has a short foot embedded in the gametophyte on which it is parasitic.
Isopoda is an order of crustaceans.Members of this group are called isopods and include both aquatic species and terrestrial species such as woodlice.All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration.
Pauropods can usually be identified because of their distinctive anal plate, which is unique to pauropods. Different species of pauropods can be identified based on the size and shape of their anal plate. The antennae are branching, biramous, and segmented, which is distinctive for the group. [11] Pauropods are usually either white or brown. [2]
One species, Minictena luteola, which only measure 1.5mm in diameter, have five different types of colloblast cells. [ 50 ] [ 51 ] In addition to colloblasts, members of the genus Haeckelia , which feed mainly on jellyfish , incorporate their victims' stinging nematocytes into their own tentacles – some cnidaria-eating nudibranchs similarly ...
Next to humans, leafcutter ants form some of the largest and most complex animal societies on Earth. In a few years, the central mound of their underground nests can grow to more than 30 m (98 ft) across, with smaller radiating mounds extending out to a radius of 80 m (260 ft), taking up 30 to 600 m 2 (320 to 6,460 sq ft) and converted into 3. ...
Aeroplankton is made up mostly of microorganisms, including viruses, about 1,000 different species of bacteria, around 40,000 varieties of fungi, and hundreds of species of protists, algae, mosses, and liverworts that live some part of their life cycle as aeroplankton, often as spores, pollen, and wind-scattered seeds.
