Crocodile

Crocodiles can be found near water and marshes in and near the Kharidian Desert:
 * Level 63 crocodiles inhabit the river and both banks of the River Elid south of Pollnivneach, north of Sophanem, and west of Nardah. (Nardah and Sophanem both have banks, although the Sophanem bank is only available for players who have completed the quest Contact!.) These crocodiles hit for a maximum of 60 life points and always drop bones with no other items.
 * Larger level 89 crocodiles infest the area east of Sophanem, along the south coast and in the eastern marshes. These hit a maximum of 120 life points. They drop big bones and may occasionally drop Long bones and Curved bones.

Most crocodiles are found in areas where Desert heat is present and thus require players to have a Water source to avoid taking damage from thirst. An exception are the level 89 crocodiles in the marshes to the far east of Sophanem.

Strategy

 * A stabbing weapon is most effective at puncturing the crocodiles' thick, scaly hides.
 * Waterskins or an Enchanted water tiara are highly recommended when fighting crocodiles in the desert. Waterskins can be refilled in various places, such as in Pollnivneach at the Fountain or at the Well using a Bucket. (Buckets can be bought at the town's General Store.
 * Desert clothing slows the rate at which desert heat affects players. However, wearing it would greatly reduce the defensive capabilities. Some players instead wear good armour. Other players wear desert clothing and use a protection Prayer (Protect from Melee or Deflect Melee) to avoid all damage, recharging prayer at the altars in Nardah or Sophanem.
 * Players wishing to buy food to heal damage in battle should take about 200 coins, to buy Kebabs in Pollnivneach.
 * Players low on both health and money can killing Goats nearby in the desert for their Desert goat horn drops and sell them at a General store. The money then can buy Kebabs in Pollnivneach.
 * Food can sometimes be obtained by searching banana trees along the banks of River Elid, though the trees do not always have Bananas.
 * Crocodiles along the River Elid will often cross the river and at times will all be on the opposite back from the player. Taking a ranged weapon and sufficient ammunition allows the player to attack the crocodiles on the other bank. Be aware that the crocodiles once attacked will cross the river to attack back and can even attack while in the river.
 * If a crocodile is killed while partially or fully in water, its drops will not appear (presumably they sink to the bottom of the water, but this is not shown in the game).
 * Players can hide at the flying carpet man in south Pollnivneach and range crocodiles that come within range. They won't approach the carpet area, so this is a Safe spot. When using this tactic, turn off Auto retaliate, as the crocodiles will often move out of range, drawing the player away from the carpet area if auto retaliate is on.
 * The Enchanted water tiara, which can be made after completing the Dealing with Scabaras quest, can be stocked up with water runes and used as a water source against desert heat. This item makes slaying crocodiles an easier task, as players can wear good armour and stay a long time in the desert. It can also be used with Guthan's set. Simply wear the tiara most of the time and switch to the Guthan's helm when necessary to heal.
 * Players killing the level 89 crocodiles may want to use the marshes to the east of Sophanem, as most of the marshes are not affected by desert heat. If water is used, there is a stream north by the nearby archaeologists where waterskins can be filled.

Trivia

 * Many players do not like being assigned crocodiles as slayer tasks, as the combination of poor drops and desert heat makes the task somewhat difficult and rather unrewarding.
 * The examine text is a quote from the classic song 'Never Smile at a Crocodile'.
 * Crocodiles supposedly swim through water to cross it, but they actually WALK ON the water. When in water, their tails are submerged, but their movement is still walking, not swimming.
 * It is strongly recommended that new players do NOT train non-combat skills near crocodiles, even if the crocodile is on the other side of a river. Crocodiles can quickly kill low-level players.
