Note: Please reference the SRD entry on true dragons for related information, including ages, damage, breath weapon ranges, and special abilities common to all true dragons.
Sea dragons are usually light or pastel green in colour with a bright yellow-green crest. They are comparable in size to green dragons, and some scholars believe them to be distantly related to green dragons.
Sea dragons live deep beneath the sea in lairs found in caves, or if the dragon can find one, a sunken ship. They will head to the surface to hunt and look for treasure. Sea dragons instinctively hate marine leviathans and fyrsnacas and will seek to destroy them if they enter the sea dragon's territory.
Combat
Sea dragons are very aggressive and often will not bother to converse with those it encounters on the open ocean. They often will stealthily trail their quarry until the best moment to leap out of the water at the quarry. If the sea dragon is spotted before it attacks, it can be bribed to converse by tossing some valuables into the water as an offering. This is no guarantee of safe passage, but will at least buy the ship some time to converse with the sea dragon and prepare for an attack.
Breath Weapon (Su): A sea dragon has one type of breath weapon, a line of poisonous spit. This poison causes primary and secondary ability damage to Con and Str (Con only in wyrmlings).
Water Breathing (Ex): A sea dragon can breathe underwater indefinitely and can freely use its breath weapon, spells, and other abilities while submerged.
Glide (Ex): Sea dragons have fin-like wings that enable the sea dragon to glide above the water for up 6 rounds (like a flying fish). The maximum height above the water they can attain is equal to the result of a Jump check for height with the normal result x10ft (if the check would normally allow a 6ft high jump, the sea dragon can reach up to 60ft in the air.)
Spell-Like Abilities: 3/day
fog cloud (adult or older), control water (old or older); 1/day
control winds (ancient or older), command plants (great wyrm).
Skills: Hide, Move Silently and Swim are considered class skills for sea dragons.

This sea dragon is still very young and has not yet developed many of its species' abilities.
Combat
At this stage of life, the sea dragon will carefully assess its foes before attacking. Generally, it will avoid combat with obviously capable adventurers (though it might be eager to converse with them)- sticking to hunting less dangerous creatures for food and treasure.
Breath Weapon (Su): A sea dragon has one type of breath weapon, a line of poisonous spit. This poison causes 1d4 primary and secondary ability damage to Con and Str if a Fortitude save vs DC 16 is failed.
Blindsense (Ex): Sea dragons can pinpoint creatures within a distance of 60 feet. Opponents the dragon can't actually see still have total concealment against the dragon.
Glide (Ex): Sea dragons have fin-like wings that enable the sea dragon to glide above the water for up 6 rounds (like a flying fish). The maximum height above the water they can attain is equal to the result of a Jump check for height with the normal result x10ft (if the check would normally allow a 6ft high jump, the sea dragon can reach up to 60ft in the air.)
Immunity to Acid (Ex): A sea dragon has 100% immunity to all acid damage.
Keen Senses (Ex): A sea dragon sees four times as well a human in shadowy illumination and twice as well in normal light. It also has darkvision out to 120 feet.
Water Breathing (Ex): A sea dragon can breathe underwater indefinitely and can freely use its breath weapon, spells, and other abilities while submerged.
Dragon Traits: Immunity to magic sleep effects and paralysis effects.
Water Subtype: Creatures with the water subtype always have swim speeds and can move in water without making Swim checks.
