Acanthostega are some of the most primitive tetrapods you'll find in the murky swamps, eight-toed on each wristless limb, lunged yet not carrying a ribcage that could support it for much time on land, as well as gilled like a fish. Acanthostega are indeed rarely seen, other than the times the pop up to the surface of the weedy murk to take a gulp of air or snatch a bug. With two sharp rows of teeth, picking up an acanthostega from his weed-filled home in the oxygen-poor shallow swamps is generally not recommended. Compounding this is another, more unusual defense. Like some salamanders, acanthostega can secrete a foul and quite sticky slime. This is used by some of the swamp-dwellers as makeshift glue.

* Sticky Secretion (Ex): As a move action, twice per day, an acanthostega grappled by an opponent may release a sticky secretion. If the target is holding the acanthostega with his hands, he has a -6 penalty to Dexterity as his fingers are glued together. The glue either wears off in 2d6 hours or can be broken with a Strength check (DC 16). A creature that has bitten onto the acanthostega and received the secretion cannot bite, and the same wearing off and breaking rules apply. A biter, however, has a 35% of having some of the glue dislodge into its throat after breaking it, dealing 1d4 points of damage as it rasps into the throat.
