Jellyfish blooms: are populations increasing globally in response to changing ocean conditions?phenomenon is demonstrated by jellyfish whose populations regularly fluctuate, apparently with climate, causing periodic blooms.

Flow and prey capture by the scyphomedusa , von Lendenfeld, 1884es. .’s body morphology is highly modified to channel flows into these capture surfaces and feeding is dependent upon this pattern. Swimming activity, and hence the creation of flows used for prey capture, is continuous, as is feeding, and plays a central role in this medusa’s foraging behaviour.作者: intuition 時間: 2025-4-1 12:51 作者: larder 時間: 2025-4-1 18:21
