Hey everyone! Back in 2019 I visited the Japan Salamander Center in Akame 48 Waterfalls (赤目四十八滝 Akameshijuhachitakki) near Nabari (Mie Prefecture). I was able to check out not only the public exhibition, but also the backroom, to which visitors normally don't have access. There I had the great opportunity to see all the kept salamanders from larvae to adult and even handle a few of them, which was really awesome. :D I can really recommend a visit in this small but very cool aquarium and also the valley itself.

General Information on Japanese giant salamanders:
"The Japanese giant salamander (Andrias japonicus) is endemic to Japan, where it is known as Ōsanshōuo (オオサンショウウオ/大山椒魚), literally meaning "giant pepper fish". With a length of up to almost 1.5 m (5 ft), it is the second-largest salamander in the world, only being surpassed by the very similar and closely related Chinese giant salamander (A. davidianus). There are only three known members of the Cryptobranchidae family: the Japanese and Chinese giant salamanders and the Eastern hellbender.
Japanese giant salamanders are widespread across rivers in southwestern Japan. The species frequently hybridizes with Chinese giant salamanders, which were introduced to the area.
Japanese Giant Salamanders can grow to be five feet long (160 cm) and 55 pounds (25 kg). The largest wild specimen on record weighed 26.3 kg and was 136 cm long. It is the second largest amphibian in the world, only next to its close relative, the Chinese Giant Salamander. Their brown and black mottled skin provides camouflage against the bottoms of streams and rivers. They have very small eyes with no eyelids and poor eye sight. Their mouths run across the width of their heads, and can open to the width of their bodies."

![How spiders catch and eat prey (Araneus) || Wie Spinnen Beute fangen und fressen (Kreuzspinnen)
A spider of the genus Araneus catches a big fly. By biting it, the spider paralyses the fly and injects digestive enzymes. Spiders usually wrap their prey up in silk and don’t eat it whole. Instead, they liquefy its entrails. Later the spider can suck up the liquefied matter.
Eine Kreuzspinne (Araneus) fängt eine dicke Fliege. Mit ihrem Biss paralysiert sie die Fliege und injiziert ihr Verdauungsenzyme. Die meisten Spinnen wickeln ihre Beute mit Hilfe ihrer Spinnenseide ein und fressen sie nicht im ganzen. Stattdessen verflüssigen sie die inneren Organe der Beute. Später kann die Spinne diese dann einfach aussaugen.
General Information on the genus Araneus:
Araneus is a genus of common orb-weaving spiders. It includes about 650 species, among which are the European garden spider and the barn spider.
Spiders of this genus present perhaps the most obvious case of sexual dimorphism among all of the orb-weaver family, with males being normally 1⁄3 to 1⁄4 the size of females. In A. diadematus, for example, last molt females can reach the body size of up to 1 in (2.5 cm), while most males seldom grow over 0.3 in (1 cm), both excluding legspan. Males are differentiated from females by a much smaller and more elongated abdomen, longer legs, and the inability to catch or consume prey bigger than themselves.
In females, the epigyne has a long scape (a tongue-like appendage). Male pedipalps have a hook-like terminal apophysis. Abdominal tubercles are present anterolaterally.
Araneus spiders possess various venoms, but will deliver a dry bite on 8 of 10 occasions. Females bite more often than males, who would rather flee or feign death.

Allgemeine Informationen über Kreuzspinnen:
Die Kreuzspinnen (Araneus) sind mit mehreren hundert Arten eine der artenreichsten Gattungen der Familie der Echten Radnetzspinnen. Sie sind weltweit verbreitet. Die Gattung ist mit über zehn nachgewiesenen Arten in Mitteleuropa vertreten. Zu ihr gehört die bekannte Gartenkreuzspinne.
Ihren Namen haben Kreuzspinnen von dem charakteristischen Kreuz auf dem vorderen Hinterleib, welches bei der Gartenkreuzspinne aus fünf Flecken (vier länglichen und einem kreisförmigen in der Mitte) und bei der Vierfleckkreuzspinne aus vier Flecken besteht. Bei den Flecken handelt es sich um Stoffwechselprodukte, die unter dem Chitinpanzer abgelagert werden. Diese Flecken sind jedoch nicht bei allen Arten der Gattung Araneus auch kreuzförmig angeordnet; die meisten Arten haben eine andersartige Zeichnung.[1]
Kreuzspinnen ernähren sich von allen Insekten, die sie in ihren Netzen fangen können, auch von Wespen, Hummeln, Bienen, Fliegen und Schmetterlingen. Die im Netz gefangene Beute wird von der Spinne gebissen und mit einem Sekretband variierender Breite aus den Spinndrüsen umwickelt. Sie dreht die Beute dabei schnell mit ihren Beinen. Beim Biss abgegebene Verdauungsenzyme zersetzen das Innere der Beute. Wenn die Spinne satt ist, spinnt sie ihre Beute erst ein und hängt sie als Vorrat in ihr Netz.[2]
