I like damselfish. I like Chromis更。但是如果有一个Chromis我爱,是Chromisleucura。Chromisleucurais a diminutive species that is often found in small groups along deep reef walls and ledges ranging from 20-120m (65-400ft). This species gets its name for its white tail, which is often tipped with extremely long and wispy filamentous extensions.
C. Leucura可变,并具有漆黑灰色至深海的地面颜色。前背刺是黄色的,骨盆鳍完全是夏纹花黄色的。其胸鳍底座上有一个大黑点,并且该斑点与其他鳍片相同的黄色阴影。背鳍和肛门鳍的末端均接近垂直且极为直截了当,这使该物种具有相当独特的外观。
它的尾鳍是白色的,两个裂片都在最外面的点上,有两到三个可变长而稀的细丝。这种特征与几种物种共享,所有物种的尺寸不超过2.5英寸。上面的摄影拼贴还具有另外两个Chromis在日本显然密切相关和同胞的物种。这些是Chromis DeltaandC。艾伦。
C. Leucurahas a patchy and scattered distribution in both Oceans. In the Pacific, it can be found quite regularly in Hawaii, Marquesas and Japan. In the Indian Ocean, this species has been reported in Mauritius and the Réunion Islands. Because of its fondness for deep waters, its very likely that this species has an undocumented larger and more extensive geographical distribution. Case in point, Australia.
This single specimen collected from the Coral Sea by Cairns Marine on the east coast of Australia presents a new range extension for this species. The disjunct distribution between Japan and Australia is likely anomalous, and its presence within the connecting Indonesian and Philippine regions should be looked out for.
丝状尾延伸和直鳍的末端C. Leucura在法属波利尼西亚的一个未描述的物种中被召回。与更广泛的分布不同C. Leucura,该物种严格是深水,在超过300英尺的深度时并不少见。尚不清楚两者是否与系统发育相关,但并非每天都会遇到一些小少女,散发着漂亮的鳍,而不是好边的性格。
