Draygon

The only way Samus Aran would be able to defeat it would be to shoot its large belly with missiles. It'd attack by ramming into the bounty hunter, shooting out an odd type of slime that would slow her down, pick her up and use its tail to attack.

It's presumably a mother, seeing that it has multiple young with it, all of which bury their guardian down in the ground once killed. It can be conclusive that every member of the species became extince once Zebes, the planet they were all on, was destroyed.
