如果您仍在阅读并关注我们的大阪更新,请欢迎来到四部分!在以前的装置中,我们参观了Makoto Matsuoka先生,并看了他的一些稀有蝴蝶鱼系列。必威官网登录随行版这次,我们将介绍另一位日本水族师和他的鱼,但是我们没有展示更多种类的物种,而是强调了一个非常独特的amthiine。Odontanthias katayamaiis a member of the deep bodied genusOdontanthias, which is exclusively deepwater and distributed all over the Pacific and Indian Ocean, with one member residing in the Atlantic Ocean. Of the many species ofOdontanthias,只有五个可用于交易。
Odontanthiasis a fascinating genus of deepwater anthias that are very stout in built with large eyes and mouths. Many species are extremely ornately decorated, with elaborate threaded filaments arising from all unpaired fins and unusual tail morphologies. InO. elizabethae, the tail filaments are long and tapering, while inO. katayamai他们是圆形的。
The fish in subject here today is not new to the world, and certainly not to this blog.Odontanthias katayamaihas been broadcasted to death every time it appears in Japan, but this is the first time that such clear photos have ever been provided for the public. It was really opportune how this fish ended up in Osaka during our visit, and allowed for some nice photos while it posed with all the finesse in the world.
Odontanthias katayamai到目前为止,只有在日本和台湾众所周知,它生活在非常深到700英尺深处的水域中。在凉爽的月份,水温下降的月份,就像许多其他深水鱼一样,它们在越来越接近地面时会发现较浅。过去,该物种与印度太平洋地区广泛混淆Odontanthiaschrysostictus, but adetailed posthighlighting this error has been made, and the two species can be differentiated based on tail characteristics.
As with many deep water fish,O. katayamai实际上是在深度并不少见。李在日本st, this species is a rather common by-catch of commercial fishing entities or by sport fishermen. At 600ft, this fish is commonly hooked on the line. Unsurprisingly, these never make it due to the trauma brought about by the rapid ascent from deepwater to the surface. It’s the same old story that we’ve been preaching in every deepwater fish post. The photos above show some example ofO. katayamai受到钩和线钓鱼带来的DC。游泳膀胱创伤导致浮力问题以及肛门的持久性是不当和快速上升的迹象。
Despite its prevalence in the wild, these are incredibly scarce in the trade and comes with a hefty price tag. Because of their deepwater nature, rebreather diving is just about the only way to go but in Japan that is not exactly a viable option. The few that do enter the trade are mostly from fishing that do miraculously survive, either by sheer luck or by intentional care taken to reel it up slowly. How exactly does this happen, I am unsure.
In this beautiful species, the ground colour is a luscious salmon with a rose wash, which intensifies into a mangosteen purple toward the tail. The coloration of this fish has led to its Japanese name of “Rose-Handai”. Handai means perch, or specifically anthias, with rose referring to the coloration. The head is encased in a yellowish-green helmet which travels up along the dorsal fin, where it is adorned in spots of the body’s coloration. Conversely, the body is stellated with spots of the dorsal fin’s coloration. The tail is trimmed in yellow and the two lobes are slightly pronounced and edged in red. All its fins with the exception of the pectorals and caudal are festooned with trailing filaments.
在日本,深海挑战者似乎是该物种的少数几个提供者之一。这个特殊的人已经坐在货架上多年了,剩下的未售出和不必要。然而,它与他们在一起的长度使鱼能够肥大,并适应了水族馆的寿命。通常害羞,这个特殊的人将前面板带着不懈的照片摆姿势。相比之下,居住在Shimokobe博士家中的另一个标本(我们将在第3部分中展出)痛苦地隐居,几乎不可能拍照。
It was a rather opportune time for us in Osaka. Had we been there even a month earlier we wouldn’t have had the chance to see this fish. ThisO. katayamairesided for a long time in Okinawa, where Deep Sea Challenger is situated. It nearly made its way to Singapore, but it ended up going to an undisclosed buyer instead.
While at Osaka, Koji took me to see a young man named Yuma Yasuda. In a dark shadowy tank at the end of the room was the faint glow of the yellow helmet belonging to this fish. It was immediately recognisable that this anthias was the same one that had been shelved at Deep Sea Challengers for a long time, and how uncanny that it ended up here in Osaka.
We’ve included a HD video of this species above. It’s enthralling to say the least, watching the ribbony fin extensions trail around as the fish makes calculated turns around its aquarium. The tank is sparsely stocked, and the only fish comparable in size is a medium sized Clarion Angelfish. A smallOdontanthias borbonius,Centropyge joculatorandLiopropoma mowbrayialso reside in this tank.
我个人爱上了这个水族馆的水上景观。岩石被密集地布置为形成一个交织的洞穴和隧道网络,并被鱼类清楚地欣赏到它的圆形圆形编织和柔软的棉针一样。在保留深水鱼时,墓穴蜂窝结构始终是额外的好处。添加壁架和悬垂性也是您可以使用的点。尽管大多数试图复制的浅礁系统的快速移动系统中皱着眉头,但在深水设置中鼓励了岩石。但是,平衡密度与孔隙率很重要,以确保岩石迷宫中的足够的水运动。
The dimly lit tank is only very weakly illuminated by blue LEDs, casting shadows and obscurity in many parts of the aquarium. It’s extremely satisfying to see a deepwater tank that is well composed, well executed and cleverly thought out. To house such an elite species would obviously require nothing but the optimal, but that being said, the optimal should always be provided in everything and for everything that’s being done.
It’s not everyday you get to see anOdontanthias katayamai,我们希望我们的照片和视频尽可能地捕捉到它的美丽。话虽如此,到目前为止,有五个物种已经进入了行业,而其他四种则以稀有性的升级顺序Odontanthias borbonius,O. fuscipinnis,O. UnimaCulatusandO. chrysostictus. Apart fromO. UnimaCulatus,我很幸运地亲自见到所有其他四种物种,并为它们拍了一些照片!以下是四个小拼贴。
还有许多其他物种出现,例如O. Rhodopeplus,O. Tapui,O. elizabethaeetc. However these are never alive when caught and are never offered to the trade, so strictly speaking there are currently only five that were at some point obtainable. That’s definitely going to change in the future though, with so much deep diving going on these days in remote areas, it’s only a matter of time before a newOdontanthiasis offered.
Once again, a big and sincere thank you to Koji Wada and Yuma Yasuda for this opportunity. We’ve attached a gallery below for more photos of this stunning species. Stay tuned for Part 3!
