I know the green skull means non-aggressive and the triangle symbol means the mob is aggressive. But I came across a mob in the East Shroud that is called Swollen Djigga and it has a different symbol - almost looks like the nuclear symbol. Anyone know what it means? It's the only mob I've seen with it thus far.
Not sure what that means in nuclear symbol but monsters will have a symbol relating to a quest if you have said quest that relates to those monsters and a symbol for if those monsters that are in your hunter log.

If it is a yellow coin looking thing, they relate to a quest. That includes the hunters log (kill 3 of each of the following species, complete a level to get the next level unlocked). And it also includes quests for guilds, like when I swapped my class they had me go kill 3 of a few different species then return. The arrows above them disappear when you kill the target amount. So check your journal.
