Xanthichthys sp。“dorsopunctatus” is an unusual triggerfish species which we have been researching for the better part of a year and half since we first encountered a specimen at a House of Fins in Greenwich CT. Last week优质海洋发表that they had a specimen of this fish which so far is only being collected from Christmas Island. Although QM states that this is the first one they’ve seen in 5 years, their specimen is actually the 5fth that we have documented over the last 15 months.
去年理查德·皮尔（Richard Pyle）写了一篇文章about some deep diving he and Brian Greene did around Christmas Island, precisely where this new triggerfish is being collected. During their Xmas Island diving they captured a specimen of triggerfish (pictured at right) like the one in question and they called it a new species. Like some other aquarist, we first believed this fish to be a hybrid cross involving at leastXanthichthys lineOptunctatus或女性，但是如果Pyle和Greene说这是一个新物种，那么我们将以鱼类学家的话来为此。此外，如果这条鱼是一种混合动力，我们希望看到它的外观有更多的变化以及更多的颜色和图案中间体。到目前为止，我们看到的5个标本的外观非常一致，这使我们同意Pyle和Greene的同意，这条鱼确实是一种新物种。我们赋予了给这条鱼的临时名称的自由X. sp。“背函数”，因为身体顶部的斑点模式是该物种最著名的特征，并且很可能这是用于描述该物种的拉丁名称。非常感谢Rob Mougey详细讨论了这条鱼，其中包括居住在他的收藏中的标本。遵循休息时间进行新的视频Xanthichthys来自圣诞节岛的Trigger鱼。
