I'm confused. Difference between favia and acan?

How do you tell these two apart?? ;D

 

fava beans are best eaten with a glass of chianti.

 

...i'm not sure if your thinking what i'm thinking but they look very different to me.....? Well favia are more of a unit as in they are a WHOLE , acans have seperate heads/polyps similar to a zoa i guess.

sorry for the crappy description but i'm confused, maybe ur thinking of a blasto? and an acan? they are more similar to me then a favia and an acan? maybe someone can chime in.


bump.

 

I was thinking the same thing. about the acans having separate heads

 

Haha bogie... I agree. Although, I prefer a glass of port

 

Hm. I keep looking at pics of these things, and while some of them follow the template you describe, even more don't seem to.

Let's try this: is this an Acan, or a favia? (And, uh, don't say ZOA, you smart alecks!)

 

ACK no ! "silence of the Lambs" .... good job Bogie ! lol

Acan's have more soft tissue to them. Actual identification is doen through Skeletal formation.

 

That looks like a favia speciosa to me although it's hard to tell without seeing it in real life. Acans are definitely more fleshy and each head is more separated (for the lordhowensis species anyway, echinata and hillae are more single units without separate heads).

It looks a little like montastrea too just to add to the confusion.

I've been using the liveaquaria.com's divers den lately to help with ID's because they attempt to put a genus and a species with each piece.
