Image of Isodictya palmata (Ellis & Solander 1786)
Sponge was attached to rope off the side of the MBL dock, clustered near many invasive sponges (such as Botrylloides diegensis). It was identified by looking at its spicules beneath a microscope. We found a mixture of spicules that were point on both ends and ones that had one round end and one pointed. The fact that there was a mixture of spicules but they were still predominantly pointed on both ends helped with the identification of this specimen.
