Physically, these mobs are pathetically weak, having only around 2k~ HP and they have no TP moves it seems. However, their nukes really pack a punch, a Blizzard IV from one is capable of nearly one shotting my Garuda at full health.
I just got done fooling around with these mobs, both Predator Claws and Wind Blade do very well against them. 2-3 BPs should be enough to bring one down, and I got 240 limit points for each kill.
I imagine nuking classes like BLM and SCH might do better against these mobs, but they seem nice for SMNs to fight as well, solo or duo.
