Integrative and Comparative Biology 45(2): 352–358.In addition, the gemmule’s outer layer is encased and protected by an endospore that is covered by a layer of spicules, which protects the gemmule from all other unfavourable environmental circumstances and also assists gemmules in maturing into adult freshwater sponges
Although most sponges are hermaphrodite but cross-fertilization is the rule because ova and sperms are produced at different times. Clip-on headphones rest on the ear and stay in place thanks to the hook that loops around your ear. Because they’re not completely covered, your ears can breathe freely and won’t overheat.
