There's a bunch of information on the temple including how to get a perfect temple with every possible attack and ability. I can't say exactly what happened in your case however, since I cannot see what it looked like before sacrificing everything.
Unique Abilities, and Sacrifices Needed to Get Them. (Taken from link)
To build the most powerful temple, sacrifice the following nine maxed
towers:
To get longer freeze time, sacrifice Ice Tower - Viral Frost. (4 - x)
To get larger freeze radius, sacrifice Ice Tower - Absolute Zero. (x - 4)
To get more corrosive glue splatter, sacrifice Glue Gunner - Bloon Liquefier. (4 - x)
To get larger glue splatter, sacrifice Glue Gunner - Glue Striker. (x - 4)
To get stronger tornadoes, sacrifice Monkey Apprentice - Tempest Tornado. (4 - x)
To get larger tornadoes, sacrifice Monkey Apprentice - Summon Phoenix. (x - 4)
To get greater missile damage against ceramic bloons, sacrifice Bomb Tower - MOAB Assassin. (x - 4)
To get six missiles per 1.5 seconds, sacrifice Mortar Tower - Big One (4 - x) or Artillery Battery (x - 4).
To get stronger sun rays, sacrifice Super Monkey - Technological Terror. (x - 4)
Note that sacrificing other tower types duplicate the 16 blade volleys per second benefit provided by sacrificing the Super Monkey - Technological Terror.
The same source says ten stacks to bring down a single MOAB. I wouldn't be surprised if they were saying that fourteen towers would bring down a ZOMG and all spawns. Unfortunately, the number isn't justified by anything there, so it's hard to say if there's any basis to it.
A ZOMG has 4000 health, compared to 700 for a BFB and 200 for a MOAB. That's 10,000 health for the MOAB-class bloons in a ZOMG (4000 + 4 * 700 + 4 * 4 * 200). It's not practical to think that four stacks of spikes would be enough to handle even the 3800 difference between a ZOMG and a regular MOAB, much less the 9800 to get a ZOMG down to ceramics.
A base spike factory creates five spike stacks. The Bigger Spikes upgrade increases that to ten spikes per stack. The MOAB-SHREDR upgrade does quadruple damage to MOAB-class bloons. That means that a 1/3 or better Spike Factory does 40 damage per stack to MOABs.
A base Bomb Tower does one damage to up to forty bloons in the blast radius. The Frag Bombs upgrade does up to eight more damage (total of nine if they all hit the same bloon). The Bigger Bombs upgrade increases the number of bloons that can be hit to fifty. MOAB maulers increase the base damage to ten and eighteen with Frag Bombs. A Monkey Fort (Monkey Village upgrade) doubles the pierce of the fragments. The maximum damage that a Bomb Tower under a Monkey Fort can do is
526 = (50 + 1) * 10 + 8 * (1 + 1)
That assumes that there are at least fifty-one MOABs in the blast radius and the blast only hits MOABs.
Note: it's possible that the missile tower upgrade changes some of these numbers. For example, the the 50 could increase. Unfortunately, I haven't been able to find any numbers on how much the missile tower upgrade changes things.

The specialty buildings are permanent.
Keep in mind they all have a disadvantage too, they improve something and give a negative bonus to something else, so buy only those who fit your strategy!
As an extra limit, you can only have one of them active at any time, so if you buy a rifle range and a super monkey lair you can only have one active, and not both. You can change wich one in the menu. Changing specialty building mid-game is not possible.
