Yes, breadcrumb sponges, belonging to the family Halichondriidae, do have spicules. These spicules are typically made of silica and serve as a structural element, providing support and protection to the sponge. However, unlike some other sponges, breadcrumb sponges may have a relatively low density of spicules, contributing to their softer, more pliable texture.
