What is the collective noun for wobbegongs?

There isn't a widely accepted or established collective noun specifically for wobbegongs.

While we have terms like "school" for fish, "flock" for birds, and "herd" for mammals, the nature of wobbegongs, being mostly solitary and ambush predators, doesn't lend itself to a traditional collective noun.

You could use a more general term like "group" or "aggregation" if you need to describe a gathering of wobbegongs.

Ultimately, if you want to be creative, you could come up with your own unique term like "lair" or "ambush" for a group of wobbegongs!
