TABLE 10. Acanthotetilla walteri Peixinho, Fernandez, Oliveira, Caires & Hajdu, 2007: comparative data on morphology, spicules and known distribution. Spicule measurements in micrometers (µm) are presented as minimum–average–maximum (or minimum–maximum) of length x thickness. Only length is presented for sigmaspires.
