Klud
The Klud is an aquatic beast in the Marvel Comics portion of the Generation One continuity family.

'Tis a monster most foul, the Klud! Native to the churning oceans of Pequod, and long thought extinct, the mighty beast is a terror of the high seas!
'Tis not Moby Dick, no indeed, so dash that thought from yer land-lubbin' brain, mate.
Marvel Comics
On the moon of VsQs, a scientist -- presumably wounded by the Matrix Spawn -- escaped in a life pod. The pod crashed in the ocean of Pequod, and was swallowed along with its dead passenger by a dying Klud, possibly the last of its breed. The Matrix energy permeating the dead scientist infused the Klud with new life.
The revitalized Klud became a terror around the city of Gottlieb, destroying several boats and attracting unwanted attention that threatened the city's vacation tourism trade. A bounty posted by city officials for the creature attracted all manner of thrill- and profit-seekers... as well as three Autobots searching for the lost Creation Matrix.
Investigating the wreckage of two boats, the Autobots encountered the Klud itself -- which promptly bit off Longtooth's leg below the knee. The enounter left the Autobot in a state of madness, driven to revenge. Longtooth stole a craft and hunted the creature for six days, finally running it down. Oddly enough, the Klud was saved by a Decepticon attack, as Thunderwing sought clues to the Matrix's whereabouts. Despite the battle, Longtooth yet again managed to draw a bead on the worn-down Klud, until Pincher managed to talk him down by reminding him of his Autobot code of honor.
Longtooth stayed his hand, and the Klud, though wounded, swam away alive.
