In Jordan Peele’s incredible 2019 horror film Us, an army of human doppelgängers called The Tethered arise to take the place of the existing human population. It hits at some of our core fears ...
Faxonius limosus, synonym Orconectes limosus, [3] is a species of crayfish in the family Cambaridae. It is native to the east coast of North America, from Quebec [2] to the lower James River, Virginia, but has also been introduced to Europe. [1] It is known commonly as the spinycheek crayfish [1] [5] or Kamberkrebs in German. Size comparison ...
The marbled crayfish or Marmorkrebs (Procambarus virginalis) is a parthenogenetic crayfish that was discovered in the pet trade in Germany in 1995. [4] [5] Marbled crayfish are closely related to the "slough crayfish", Procambarus fallax, [6] which is widely distributed across Florida. [7] No natural populations of marbled crayfish are known.
From this, it can be inferred that the crayfish spends most its time moving very slowly, or not at all, to conserve energy. Since food is scarce in this environment and there are few opportunities to feed, these crayfish are likely very opportunistic foragers. [5] Other than this, little is known about the behaviour of C. zophonastes. To better ...
Females can produce full clones of themselves through a modification of the normal meiosis process used to produce haploid egg cells for sexual reproduction. The female's germ cells undergo a process of premeiotic genome doubling, or endoreduplication, so that two consecutive division cycles in the process of meiosis result in a diploid, rather than haploid, genome.
Red swamp crayfish outcompete other native species for food and habitat — and can cause structural damage to dams and levees. Invasive crayfish crisis: Scientists' quest to protect native ...
Pacifastacus fortis (known as the Shasta crayfish or placid crayfish) is an endangered crayfish species endemic to Shasta County, California, where it is found and first described in 1914, only in isolated spots along the Pit River and Fall River Mills. [4] It is estimated that there are a total of roughly 4000 of the species still alive today. [5]
