The kroclion is a xenoc predator animal native to the continent of Amarisk, on the colony world of Lalonde. It is a very large and dangerous creature, feared by humans and other animals; even the sayce runs from it. However, the kroclion is not often encountered by the human colonists of Lalonde as it is an inhabitant of the open savannah, whereas the human settlements are normally found in the deep jungles along the tributaries of the river Juliffe.

The adult kroclion is nearly 4 metres in length and weighs in at half a tonne. Its hide is a sandy yellow colour, helping the kroclion to blend in with the background. It has small eyes and extremely sharp and fearsome teeth. Although the kroclion is a land creature, its head resembles that of a terrestrial shark grafted onto its body.
