Ligia Cinerascens
''Ligia cinerascens'' is a woodlouse in the family Ligiidae. Description ''L. cinerascens'' is very similar to '' L. occidentalis'' with more antenna segments, but shorter overall antennal length. It can be distinguished from '' L. exotica'' by its shorter antennae and uropods, as well as its uniformly gray color and granular texture. The species name ''cinerascens'' comes from the Latin for "ashy," referring to the gray color of this species. Life cycle In the wild, ''L. cinerascens'' usually lives about a year (overwintering once), but occasionally lives up to 2.5 years (overwintering twice). Females breed in their first year for five months, then die before the second winter, typically producing one brood or two at the most. Reared in the lab, ''L. cinerascens'' has a longer lifespan and may produce three or more broods in a lifetime. ''L. cinerascens'' is parasitized by '' Thinoseius setifer'', a mite attaching to the woodlouse's pleopods. Distribution ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gustav Henrik Andreas Budde-Lund
Gustav Henrik Andreas Budde-Lund (11 January 1846 – 19 September 1911) was a Danish invertebrate zoologist. In 1868, he co-founded the ''Entomologisk Forening'', alongside Rasmus William Traugott Schlick, Carl August Møller, Andreas Haas (zoologist), Andreas Haas and Ivar Frederik Christian Ammitzbøll. He was a student of entomologist J. C. Schiødte, and became a leading authority on terrestrial isopods (Woodlouse, woodlice, pill bugs and relatives), describing over 70 genera and around 500 species. He married in 1875 and in 1885 produced his seminal work ''Crustacea Isopoda terrestria''. The woodlouse genus ''Buddelundiella'' was named in his honour by Filippo Silvestri in 1897.

Woodlouse
Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects. Woodlice evolved from marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. This makes them quite unique among the crustaceans, being one of the few lineages to have transitioned into a fully terrestrial environment. Woodlice have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments like those of the genus ''Ligia''. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape (:wiktionary:conglobate, conglobate) as a defensive mechanism or to conserve moisture; others have partial rolling ability, but most cannot ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Ligiidae
Ligiidae is a family of woodlice, the only family in the infraorder Diplocheta.

Ligia Occidentalis
''Ligia occidentalis'', the western sea slater, is a species of sea slater of the family Ligiidae, in the genus Ligia. ''L. occidentalis'' is a habitat generalist of rocky shores. It is found on the Pacific coast of North America from Mexico to British Columbia British Columbia is the westernmost Provinces and territories of Canada, province of Canada. Situated in the Pacific Northwest between the Pacific Ocean and the Rocky Mountains, the province has a diverse geography, with rugged landscapes that .... The western sea slater is separated from '' L. pallasii'' by its much longer uropods and its larger eyes which are set closer together, along with its sleeker body. This species has a tendency to bolt when disturbed. These sea slaters hide in rocky crevices above the high tide line during the day. It may emerge at night or in cooler weather to scavenge for algae and detritus along beaches or rocky cliffs. Western sea slaters must keep their gills moist in order to breathe b ...

Antenna (biology)
An antenna (plural: antennae) is one of a pair of appendages used for Sensory system, sensing in arthropods. Antennae are sometimes referred to as ''feelers''. Antennae are connected to the first one or two Segmentation (biology), segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing tactition, touch, air motion, heat, vibration (sound), and especially insect olfaction, smell or gustation, taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate (biology), substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pleopod
The anatomy of a decapod consists of 20 body segments grouped into two main body parts: the cephalothorax and the pleon (abdomen). Each segment – often called a somite – may possess one pair of appendages, although in various groups these may be reduced or missing. Cephalothorax Head # antennules # antennae # mandibles # first maxillae # second maxillae The head also bears the (usually stalked) compound eyes. The distal portion of a mandible or maxilla which has a sensory function is known as a palp. Thorax / pereon #first maxillipeds #second maxillipeds #third maxillipeds #first pereiopods #second pereiopods #third pereiopods #fourth pereiopods #fifth pereiopods Maxillipeds are appendages modified to function as mouthparts. Particularly in the less advanced decapods, these can be very similar to the pereiopods. Pereiopods are primarily walking legs and are also used for gathering food. They are also the ten legs from which decapods take their name. Those pereiopods which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuril Islands
The Kuril Islands or Kurile Islands are a volcanic archipelago administered as part of Sakhalin Oblast in the Russian Far East. The islands stretch approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia, separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor islets. The Kuril Islands consist of the Greater Kuril Chain and, at the southwest end, the parallel Lesser Kuril Chain. The group termed the 'South Kurils' consists of those of the Lesser Kuril Chain together with Kunashir and Iturup in the Greater Kuril Chain. The Vries Strait between Iturup and Urup forms the Miyabe Line dividing the North and South Kurils. The Kuril Islands cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their Invasion of the Kuril Islands, 1945 invasion by the Soviet Union near the end of World War II. Japan claims the four southernmost islands, including two of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
