Tridacna elongatissimais a species of giant clam that was first described from the Western Indian Ocean all the way back in 1856. Somewhere along the way the characteristics of this species were thought to be synonymous withTridacna maximabut at long last this unique species is getting the recognition it deserves.
我们曾经almost早在2015年,我们注意到some large clams from Mozambique绝对不是最大蛤lam,而是做出了错误的假设Tridacna squamosina(=T. costata). Then we did it again just last fall some when肯尼亚类似蛤的图像turned up on some dive photos, but with new information we are more confident now that these are both the long lostTridacna elongatissima.
In both sets of images you can tell from the surrounding marine life that these are not small clams – not the scale ofT. gigas, but still much larger than what we expect from any T.maxima we’ve ever seen or heard of. Furthermore the vertical folds of the shells are some of the deepest and most extreme we’ve ever seen and unlike almost all other clams known, but reminiscent of the poorly knownT. rosewateri.
Tridacna elongatissima最初是从莫桑比克描述的,但新的分类学名称来自最近深入的遗传研究,从西印度洋的所有蛤s中看,并得出了一些有趣的结论。在这一广泛范围内进行了14多年的研究人员和数年的遗传组织,进行遗传分析,然后进行统计分析,以更清晰地了解印度洋和哪里的蛤la。
The results concluded that collected samples only showedTridacna squamosina发生在红海和Tridacna elongatissimaoccurring in the southwestern Indian Ocean. Furthermore, an obscure description of a new species from 2017,Tridacna lorenziappeared to be the same asT. rosewateri前面提到过。作为巨型蛤lam的忠实拥护者,这是我们阅读的最好的论文之一,以了解更多,更好地了解这个迷人的群体,并更多地了解来自西印度洋的晦涩和被遗忘的物种。[[Journal of Biogeography]
