Dysderidae, also known as woodlouse hunters, sowbug-eating spiders, and cell spiders, is a family of araneomorph spiders first described by Carl Ludwig Koch in 1837. [ 1 ] [ page needed ] They are found primarily in Eurasia , extending into North Africa with very few species occurring in South America.
Ligia oceanica, Fort-la-Latte, Plévenon, Bretagne, France. The mitochondrial genome of L. oceanica was sequenced in 2006. It is a circular, double-stranded DNA molecule, with a size of 15,289 base pairs.
Coastal Ligia species exhibit a mixture of terrestrial and marine characteristics, drying out easily, needing moist air and proximity to water to retain water. [1] While they have gills and can exchange gas under water, they only do so when escaping terrestrial predators or being dislodged by wave action .
Most of the more than 400,000 whitetail hunters who will be afield this weekend on the Minnesota firearms deer opener hope to shoot a big buck. Few will. Everyone, however, can hunt successfully.
Ligia exotica can grow to 4 centimetres (1.6 inches) in length, with the males being rather bigger than the females. The general colour is dark grey, sometimes with brown flecks, and the appendages are pale brown.
Dysdera are one of the few known arthropods to hunt and prey on woodlice, one of their main food sources. These spiders have wide jaws and large fangs to help to overcome the solid armor-like shells of woodlice. It makes them powerful predators for their size, allowing them to dominate or kill competitors, such as centipedes or other spiders.
The world’s oldest known wild bird has sparked “special joy” among scientists after she laid an egg – her first in four years – at the age of 74.
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. [4] This makes them quite unique among the crustaceans, being one of the few lineages to have transitioned into a fully terrestrial environment.
