a saltwater crocodile  

Crocodiles are located near the pools just north of receiving the quest, they are all roamers, they are versy social, and social with other crocs as well. Basiliks are not social.
I have seem them drop, Pearlescent Crocodilian Tooth, Crocodilian Tooth, Crocodilian Hides, Pearlescent Crocodilian Claw, and Sunshard Pepples.
In this zone you can not shoot arrows at mobs underwater unless you are underwater as well.
They flee at 19% health, maximum I have seen that they hit for is 224, standard mob so no rampage, or summons.
Easy to kite if you want to pull them up on the small plateau that has NPC Daemon Darkdawn(missions).

Crocodilian Tooth = 5p, 8g, 2s, 4c
Pearlescent Crocodilian Claw = 37p, 3g, 3s, 4c
Crocodilian Hide = 19p, 4s, 8c
Pearlescent Crocodilian Tooth = 25p, 5g, 2s, 9c
Sunshard Pepples = 1s
