生活在珊瑚礁上的热带虾多种多样,且大多能为礁鱼提供清洁服务。常见的带有红色条纹的清洁虾(学名Lysmata amboinensis)我们都非常熟悉,但在尾瘦虾属(Urocaridella)中还有一些较小的清洁虾我们不甚了解。

 

除了我们曾介绍过的Arrow清洁虾之外,尾瘦虾属至今只新添了一个新物种Urocaridella degravei。这个物种以前被称为Urocaridella sp.C,广泛分布在印度尼西亚,包括巴厘岛和巴布亚新几内亚,非常普遍。

 

 

根据其颜色和图案,人们很容易将新发现的Degrave清洁虾与相似的虾区分开来。几乎所有尾瘦虾属物种都有着清晰的红色和白色斑点,但Degravei清洁虾身上的斑点是红色和黄色的。此外,Degrave清洁虾的腹部有一条黄色条纹,延伸至尾巴上成为Y形。

 

 

 

 

 

虽然尾瘦虾属物种也是清洁虾,但它们往往远离珊瑚礁,就像某些Periclemenes虾物种一样。Arrow清洁虾并不罕见,但由于难以处理和运输,因此它们很少见于水族箱。这是一个遗憾,因为它们有些可以为微缸增加美丽的点缀。

There’s an incredible diversity of tropical shrimps that live on coral reefs and a whole suite of them perform cleaning services for reef fish. We’re all very familiar with the common red line cleaner shrimp, Lysmata amboinensis but there’s a group of smaller cleaner shrimp in the genus Urocaridella. 

 

We’ve introduced the Arrow Cleaner Shrimp in a previous article but today the genus just got a little bit bigger with the description of a new species, Urocaridella degravei. Previously known as Urocaridella sp C this widespread shrimp is quite widespread in its distribution throughout Indonesia including Bali and Papua New Guinea. 

 

The freshly minted Degrave’s cleaner shrimp is easy to distinguish from similar shrimp based on coloration and pattern. Nearly all other Urocaridella are clear with red and white spots but U. degravei has red and yellow spots on its body. Furthermore a yellow line runs along the abdomen of Degrave’s cleaner shrimp and it splits into a Y shape on the tail. 

 

While they are cleaner shrimp, the species of Urocaridella tend to hover away from the reef much like some species of Periclemenes shrimp. The Arrow Cleaner Shrimp are not rare by any means but they are hard challenging to handle and transport, which is why they are rarely seen in aquariums. This is a pity because a small group of them can make for a beautiful addition to nano reef tanks as you can see in the video below.
