A crayfish capable of cloning itself is taking over European countries — and the EU has banned its transport, production, and release, reports NYT.
It’s later revealed that the Tethered are genetic clones created by the government and abandoned. Human cloning is, as yet, still beyond our reach. But nature has the process lock.
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.
Procambarus is a genus of crayfish in the family Cambaridae, all native to North and Central America. It includes a number of troglobitic species, and the marbled crayfish (marmorkrebs), which is parthenogenetic. Originally described as a subgenus for four species, it now contains around 161 species.
Spinycheek crayfish (Orconectes limosus) can reproduce both sexually and by parthenogenesis. [20] The Louisiana red swamp crayfish (Procambarus clarkii), which normally reproduces sexually, has also been suggested to reproduce by parthenogenesis, [21] although no individuals of this species have been reared this way in the lab.
The fish Channa maculata is an invasive species in parts of Madagascar, and it is known to feed on young crayfish. [1] Astacoides is also harvested by local people, often before the crayfish are able to reach reproductive age. [1] The greater threat to Astacoides crayfish, however, is from habitat loss.
Procambarus fallax (also known as deceitful crayfish [1] or slough crayfish [2] [4]) is a species of crayfish in the genus Procambarus. It lives in tributaries of the Satilla River in Georgia and Florida. [1] [2] It is the closest relative to the parthenogenetic marbled crayfish, Procambarus virginalis. [5] [6]
Cloning animals requires procedures that can cause pain and distress, and there can be high failure and mortality rates.” Being able to produce genetically identical monkeys could be useful ...
