If you've ever read any stories about Sherlock Holmes, you may remember that he once solved a mystery in which a man died due to injuries sustained from a lion's mane jellyfish. Apparently, the victim encountered this free-floating jellyfish in a pool of water, was stung, and died suddenly. From this information, you can deduce that the victim encountered the jellyfish in what form?

Question

Quizplus · Accepted Answer

The fact that the victim encountered the jellyfish in a pool of water suggests that it was a free-swimming form, which is the medusa stage of a jellyfish's life cycle. Polyps are typically attached to surfaces, anemones are stationary, trocophores are a type of larva, and placozoans are not known to have a swimming form.
