Improved Grab (Ex)
To use this ability, a behir must hit a creature of any size 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 it establishes a hold and can attempt to constrict the opponent or [swallow the opponent] [in the following round].
ってなってるんですけど、in the following roundが実はswallow the opponentのみにかかってるって解釈は無理ありますかねー？
ダイア・シャークとか、つかみ強化と飲み込みを持ってる（そして締めつけは持ってない）モンスターの記述に引きずられてこういう記述になったのかも？
ってのはただの憶測でしょうかね？
