文摘

•: B. bigelowii has a haptonema, and can use it for adhesion to external substrates.
•: B. bigelowii has a unique cell surface structure called pentalith-substrate.
•: Pentalith-substrate and organic layers probably play some roles in calcification.
•: Pentalith calcification probably takes place extracellularly
•: Pentaliths contain relatively higher amounts of Mg than typical heterococcoliths.
