Jellyfish

Description:

This particular is rather small, the bell is between 1-2 cm in size and the tentacles were flowing up to 0.5 meters. Again, nice to see, but painful if stung by the tentacles. Jellyfish or jellies are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey. Jellyfish are found in every ocean, from the surface to the deep sea. Scyphozoans are exclusively marine, but some hydrozoans live in freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal.

Notes:

Almost all Jellyfishes stings, some more deadly than others. Generally, the stings causes itchiness and pain and will heal within a few days although some will takes longer than a month! During this dive trip to Moal-Boal, there were a lot of this specie of Jellyfish, practically thousands and it was impossible to avoid them, even with wearing hood. They mostly stay at the top 10 meters from the surface, probably requiring sunlight.
