today's invertebrate.............tetraplatia volitans

tetraplatia volitans is a wiggly little jelly with a very unpleasant secret. while they may look very polite and orderly they actually have a nasty gambling addiction and will readily take money from charities and your loved ones to fuel it!!

and guess what? their gambling addiction isn't even the previously mentioned unpleasant secret!!!!

glorpiness rating: you don't want to know.....

narcomedusae jellyfish -; ༉‧₊˚✧

the narcomedusae jellyfish is a really cool jellyfish that is found in the mediterranean sea in large groups in deep waters. this jellyfish is in an order of hydrozoans in the subclass trachylinae, which dont usually have a polyp stage! as you can see, the medusa has a dome shaped bell with very thin sides, and the tentacles are attatched above the lobed margin of the bell with a gastric pouch above each. and!! there are no bulbs on the tentacles and no radial canals!!

narcomedusae use their tentacles to catch big and fast moving fish. they do this by holding their tentacles perpendicular to the direction they are swimming so they can cover a large area, and then if something is caught they bend the tentacle inwards and coil them at the tips of their mouths.

overall i think the narcomedusae is a really cool jellyfish, a solid 8/10!!

Cambrian Explosion Month #06: Phylum Cnidaria – Medusozoa

 The medusozoans are a group of cnidarians that includes modern true jellyfish, box jellyfish, stalked jellyfish, hydrozoans, and the weird fish egg parasite Polypodium.

Due to their soft gelatinous bodies their fossil record is very sparse. While vague fossilized blobs tend get interpreted as jellyfish fairly often, many of them turn out to be trace fossils or inorganic structures, and definite preserved medusae are only found in a few sites of exceptional preservation.

Among those rare examples of fossil jellies there are some amazingly well-preserved specimens known from the mid-Cambrian, discovered in the Marjum Formation in Utah, USA (~505 million years ago).

None of these species have been given their own names, and they're all tiny, only around 1cm in diameter (0.4"). But their anatomy is still preserved in enough detail to tentatively classify them into known lineages, including the box jelly, narcomedusan, and semaeostomean shown here.

Much larger Cambrian jellyfish have been also found in Death Valley, California, and in Wisconscin, representing preserved mass stranding events on ancient shorelines. Some of these jellies were up to about 50cm in diameter (20"), indicating that large soft-bodied animals were much more common in Cambrian seas than previously thought.

Jelly n.6 - 🐶 BERNIANA 🐶

● They love humans, but its poison is really dangerous. If you touch it better not in the tentacles.

● It never stops moving, always looking for ways to have fun. It can be tiring sometimes.

● Very careful with Berniana XL, it loves to “lick” with its tentacle tongue. It is one of the most dangerous poisons.
