Again, the vast majority of sponges draw in microscopic material through tiny pores, but this sponge has tree-like branches with large glass globes covered in Velcro-like sharp spikes that impale swimming prey! Pressure-adapted microbes have been retrieved from trenches down to 11, m, and have been found in the laboratory to have all these adaptations pressure-resistant biomolecules and piezolytes.
