Mancae are born with 6 segments and gain an additional one after their first molt. Whole woodlouse. While the broader phylogeny of the Oniscideans has not been settled, eleven infraorders / sections are agreed on with 3,937 species validated in scientific literature in 2004 [ 5 ] and 3,710 species in 2014 out of an estimated total of 5,000 ...
Louse (pl.: lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. [1] [2] [3]
Argulus foliaceus, also known as the common fish louse, is a species of fish lice in the family Argulidae. [1] It is "the most common and widespread native argulid in the Palaearctic " [ 2 ] and "one of the most widespread crustacean ectoparasites of freshwater fish in the world", considering its distribution and range of hosts.

Due to the quantum mechanical wave nature of particles, diffraction effects have also been observed with atoms—effects which are similar to those in the case of light. . Chapman et al. carried out an experiment in which a collimated beam of sodium atoms was passed through two diffraction gratings (the second used as a mask) to observe the Talbot effect and measure the Talbot length
Head louse egg (nit) attached to hair shaft of host. Like most insects, head lice are oviparous. Females lay about three or four eggs per day. Louse eggs (also known as nits), are attached near the base of a host hair shaft. [11] [12] Eggs are usually laid on the base of the hair, 3–5 mm off the scalp surface.
On July 25, 1978, the world's first "test tube baby" was born. Louise Brown was the first person conceived through in vitro fertilization (IVF) and her birth eventually led to one of her doctors ...
The lobster louse was first reported in 1826 by Audoin & Milne-Edwards. [2] N. astaci has been found on lobsters inhabiting locations including Scotland, [3] Lundy Island in the Bristol Channel [4] and as far south as France and Portugal. [5] The louse possesses a narrow suctorial mouthpart to feed on host haemolymph.
One phase is above the interface, and the other phase is below. Polymerization occurs where the two phases meet, at the interface. Interfacial polymerization is a type of step-growth polymerization in which polymerization occurs at the interface between two immiscible phases (generally two liquids), resulting in a polymer that is constrained to ...
