Yammosk

Atmosphere Generation: The lung capacity of a yammosk allows it to hold enough air to support thousands of oxygen-breathing creatures for several hours. A yammosk can produce a large, transparent bubble of oxygen, but can only do so once every 24 hours. Crew Skill Bonus: A yammosk can assist the crews of all of its assigned Yuuzhan Vong capital ships within 10,000 kilometers. This results in a +2D bonus to all rolls by these crews that involve Astrogation, Gunnery, Piloting, and Sensors skills. This bonus does not affect non-capital-scale Yuuzhan Vong ships, nor do multiple yammosks provide additional bonuses. If the link between the yammosk and its fleet is somehow severed, this bonus is lost. Note that this bonus has already been factored into the Crew Skills of all converted Yuuzhan Vong ships that it would normally apply to. Gravitic Telepathy: Yammosks can both receive and broadcast thoughts, allowing it to treat all of its assigned forces (the crew and troops of any ships, including non-capital-scale coralskippers) as being within sight and voice range. This effect extends to a range of 10,000 kilometers. Shared Knowledge: Yammosks share their collected memories with their offspring. While a newly-born yammosk will possess these memories, however, it takes time before this knowledge can be applied to the creature's skills. Starfighter Scale: Due to their size, yammosk are considered starfighter-scale. Subsensory Awareness: The yammosk has the ability to judge a target's basic state of mind, and is a form of empathy. By making a successful Perception check (difficulty of the target's Control or Knowledge: Willpower), a yammosk can gain a +1D bonus on all Con, Intimidation, Persuasion, and Willpower rolls made against that target. This effect lasts one minute per use. Natural Weapons: Bite: The bite of a yammosk inflicts its Strength +1D+2 damage (6D+2 starfighter-scale). Tentacles: Although the yammosk has six tentacles listed as natural weapons, the damage rating is given as "special," and no other notation is made in the entry's text. As such, assume that the tentacles can be used to grapple and crush opponents using the yammosk's Strength rating as the attack's damage.

Size: Heads can be up to 19 meters in diameter, with tendrils that can span more than 100 kilometers.
