Phymastreaa New Genus?
在珊瑚命名的一些大规模变化之后,在国际“巩膜SylerInian Systemation工作组”的一些研究活动之后。该组使用新的形态学和分子遗传学分析,并最终在珊瑚命名中改变了相当的事情。斑点是其中之一。
One of their tasks is separating genus from the Atlantic and Indo-Pacific zones, and as a consequence,Montastrea和Favia仅用于大西洋物种,并被替换Phymastrea和Dipsastraeafor the Indo-pacific species.
其他一些前境内太平洋的属Montastrea, have also been reclassified asAstrea and Paramontastrea。他们有所不同Phymastreaby mainly having smaller polyps.
Phymastrea colemani is a coral more popular than you think:
We see oftenPhymastreawrongly identified asMicromussa,Favia,Acanthastrea… so we thought we could make a post to help everybody properly identify it. AndPhymastrea colemaniis a very popular coral.
Colonies are massives, either flat or dome-shaped. Corallites are conical with their own walls and monocentric. corallites are separated by their own walls. Corallites vary in size due to extra-tentacular budding.
Not to be misidentified with other genus:
Favia(NowDipsastraea对于印度太平洋物种而言是最亲近的。
Differences include: Intra-tentacular budding forPhymastrea, whileDipsastraea (Favia)或者Micromussa在做extra-tentacular budding.
Therra-theracular萌芽通常是珊瑚,看起来更加挤满了珊瑚。该物种的息肉小于大多数Acanthastrea。只有几个迪斯斯特里亚和Micromussahave polyps this small.
WithPhymastrea隔膜尺寸交替,而隔膜尺寸更加规律Dipsastraea。In comparison,Microomussa,或者Favite.have shared wall between corallites, which makes them easy to separate fromPhymastrea。
D. COLEMANI.:息肉的直径为5-8毫米。隔膜由替代的不同大小的两个不同尺寸的循环组成。口腔周围清晰可见耳状。
It is a classic coral found in protected and turbid reefs, but doesn’t really mind a bit of flow. We usually find it encrusting on the side of other corals, or deeper below 10 m (30 feet).
If you are keeping these corals in aquariums the light and flow should be medium. Like all LPS, regular feeding is a good way to increase growth.
其他种类的属:
The genus is composed of 4 different species:
Other species includeP. magnistellata,which very much looks like Favia, with its spaced corallites, except for the extra-tentacular budding.
P. multipunctata and P。valenciennesi那非常相似P. colemani, but without paliform lobes and slightly bigger corallites.
Hope this help to understand a little bit more this beautiful coral.
