When a tullimonstrum hits with a bite attack, it automatically grapples its foe, dealing automatic bite damage each round. The tullimonstrum loses its Dexterity bonus to AC and has an AC of 12, but it holds on with great tenacity. While attached, a tullimonstrum has a +8 racial bonus to maintain its grapple on a foe. An attached tullimonstrum can be struck with a weapon or grappled itself—if its prey manages to succeed at a grapple check or Escape Artist check against it, the tullimonstrum is dislodged.

Environment any oceans
Organization solitary, pair, group (3–5), or school (6–20)
