The Paradox of the Court, also known as the counterdilemma of Euathlus, is a very old problem in logic stemming from ancient Greece. It is said that the famous sophist Protagoras took on a pupil, Euathlus, on the understanding that the student pay Protagoras for his instruction after he wins his first court case. After instruction, Euathlus decided to not enter the profession of law, and Protagoras decided to sue Euathlus for the amount owed.

Protagoras argued that if he won the case he would be paid his money. If Euathlus won the case, Protagoras would still be paid according to the original contract, because Euathlus would have won his first case.

Euathlus is made up of dwarf tarantulas, most not exceeding three inches in leg-span. They are beautifully colored and have great hair-work on both their carapace and abdomen. They all come from Chile and are very easy to keep. For the most part they are also docile, though most species are a bit skittish. The exception is sp. red which actually has the best temperament of any tarantula I have ever kept. If a tarantula can be said to have a sweet disposition then this one definitely has it.

Scientific classification

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Subphylum: Chelicerata
  • Class: Arachnida
  • Order: Araneae
  • Infraorder: Mygalomorphae
  • Family: Theraphosidae
  • Genus: Euathlus

Habitat

Predomina un clima templado frío con lluvias invernales. La temperatura media anual es de 9,6° C. Las temperaturas invernales de junio a agosto apenas superan los 4° C. Las precipitaciones anuales se concentran mayoritariamente en los meses de invierno alcanzando a 1.072,9 mm.

Euathlus sp 1 (parda) construye sus madrigueras bajo grandes rocas en las laderas precordilleranas, donde al igual que en la V región predomina la vegetación de bosque esclerófilo formado por especies como quillay, litre, belloto (Beilschmiedia berteroana), boldo y peumo. En las laderas de solana por su parte predominan las formaciones de espinos (Acasia caven).

Diet

Crickets, meal worms, wax worms, Blaptica dubia or Blatta lateralis roaches. Please do not offer wild caught prey, as it may contain pesticides which can harm your Tarantula.

Water

Make sure to offer a water bowl, the size should be half the size of the species. Do not use any sponges, cotton balls or paper towel or water crystals inside of water bowl, just clean water. Small rocks may be added. Cleaning the water bowl once a week or when you feel it is necessary. Crickets or roaches may end up dead in the water, in which case you should clean it right away. Spiderlings are too small to have a water bowl, misting one side of the enclosure wall 1-2 times a week, should be plenty enough.

Life span

I estimate that this species can live up to 10-20 years if well cared for.
