Jellyfish and squids are both marine animals, but they belong to different phyla. Jellyfish are part of the phylum Cnidaria, while squids are part of the phylum Mollusca.
One of the main differences between the two is their body structure. Jellyfish have a gelatinous umbrella-shaped body with tentacles hanging down, while squids have a more elongated body with a distinct head, mantle, and tentacles.
Another difference is their mode of movement. Jellyfish move by pulsating their bell-shaped body, allowing them to drift with ocean currents, while squids are fast swimmers and use jet propulsion to move through the water.
Additionally, jellyfish have stinging cells called nematocysts on their tentacles that they use to capture prey and defend themselves, while squids use their tentacles to catch and grasp their prey.
These are just a few of the many differences between jellyfish and squids!
