This monstrous, fish-like creature is of a primitive, nightmarish design with large, scissor-like cutting jaws filled with serrated, razor-sharp bone in place of teeth. Its jointed neck attaches the great head to a scaleless body, and tnstead of scales, along its sides are hinged shields of thick bone forming an exoskeleton. Two large fins grow from each side of the body and many feathery fins grow down its eel-like tail.

Combat:
The dinichthys is nigh king of the seas, snatching up and swallowing smaller creatures, or even attacking and picking fights with larger creatures. It is said that it has even made meals out of dire sharks, the dinichthys' dense natural armoring foiling even the shark's powerful bites.

Improved Grab (Ex): To use this ability, a dinichthys must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can try to swallow the foe in the following round.

Swallow Whole (Ex): A dinichthys can try to swallow a grabbed opponent of up to one size smaller by making a successful grapple check. Once inside, the opponent takes 2d6+6 points of bludgeoning damage plus 1d8+4 points of acid damage per round from the dinichthys digestive juices. A swallowed creature can cut its way out using a light slashing or piercing weapon by dealing 30 points of damage to the dinichthys digestive tract and its outter exoskeleton (AC 14). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out.

Skills: A dinichthys has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line

Tanystropheus



The waves crash nearby, and seagulls lift off suddenly with a squawk. A reptilian head pokes itself out of the water and juts out onto the shore. It appears as a stiff-bodied snake until a long body comes along. Turning, it hisses and suddenly the head snaps up twelve feet high. It scurries towards you, jaws gaping far overhead...

A tanystropheus is an extraordinarily proportioned, sprawling reptile with a stiff 8-12 foot tall neck. Its lowly held, long body nearly, or in fact does, drag along the ground in places, supported by two stubby front legs, and two longer, bent back legs. Each foot ends in five toes with curved claws. The tail is very long, and used as a counter balance for the neck.

Combat:
Tanystropheus prefers smaller creatures to feed upon, mostly large fish and birds, though it can be highly territorial, attacking in earnest any creatures that trespasses.

It strikes with blindingly quick downward snaps of its neck, grabbing and tearing with its teeth. If the foe comes too close it'll rear up onto its back legs and slash with its front claws.

If an opponent proves too much, it will flee into any nearby water.

Skills:
A tanefee gets a +3 bonus on all spot, listen, and swim checks.

They both look good, but I'd say the reach was 5ft (20ft with bite). That way, those "stubby front legs" don't seem to have the power of superelongation.

Demiurge out.

I'm going with Demiurge. I always loved Tanystropheus, the lizard with a 16-foot neck.

What would the average hp be for a creature like this? I figured around 73 hit points, but to me, that seems far too weak. What do you suggest?

well, considering it has +115 hit points before you even roll it up, I think its a bit touger than you think

Well, f@ck my hat! I didn't see that! So, that would mean it has... what... [Does quick arithmetic on his fingers] 188 hitpoints? Sound about right?

I got around 179, but close enough either way
