Abstract

Encrusting cheilostome bryozoans structurally resemble aggregates of small boxes, with both frontal and vertical walls capable of resisting forces generated by water-borne debris or predators. Both the skeletal strength and design of the walls are important in determining the relative ability of the colony to resist damage. Two mechanical tests, puncture and compression, performed on nine species of tropical bryozoans reveal significant differences in skeletal strength both between species and between the outer and inner regions of colonies. Puncture stresses required to break through the frontal walls of zooids range from 0.8 to 291.0 MNm
