Love the #Hype4Hydrozoa for this lovely jelly!
This red eye jelly (Polyorchis penicillatus) is thought to be an ambush predator. The jelly will spread out its tentacles and slowly sink in the water (“sink fishing”), ensnaring any unsuspecting arthropod below.

If you know me I am always #Hype4Hydrozoa, and lucky me Hydrozoa or “water animals” includes over 3500 species to get excited about, spanning from freshwater to the deep ocean!

Okay “true” and “box” jellies, but stalked jellyfish?
Staurozoa includes ~50 species that have similar structures as a “typical” swimming medusa, but instead these stauromedusae attach to substrate like algae or rocks!

What are medusozoans anyway?
Medusa = jellyfish, or the swimming life stage present in the lineages of Medusozoa, a subphylum in Cnidaria! The jellyfish stage (typically) proceeds after the benthic polyp stage.
📷 Sanderia polyps and young jellies (ephyrae)!

Medusozoan classes includes:
• Scyphozoa (“true” jellies)
• Cubozoa (box jellies)
• Staurozoa (stalked jellies)
• Hydrozoa (water animals)
Jellyfish are found across these groups, but in some cases the jellyfish stage has been highly modified or even lost!

“True jellyfish” you say?
Scyphozoa may be called true jellies since they often grow into larger jellyfish (easier to see!) in marine habitats across the world. There are ~200 described species such as moons, sea nettles, upside-downs, and egg yolk jellies!

And box jellyfish? Seems odd…
In more ways than one! Cubozoans or box jellies have cube-shaped bells and 1 or more tentacles at each of the four “corners”. Some species are known for having complex eyes, fast swimming speeds, or potent venoms!

Several jellies can be longer and larger than humans!
Lion’s Mane Jellyfish (genus Cyanea): 3m bell diameter, 30+ m long tentacles!

These moon jellies are just a few months old, but have grown fast on a steady diet of brine shrimp (Artemia sp.) or “sea monkeys.” You can see this jelly’s last meal still inside!

Okay so jellyfish often live as polyps for a while, but polyps don’t sting right?
Not so! The polyp stage also contains stinging cells, which house the venom-filled structures that give jellies their sting.

Can you spot the strobilating polyp? It’s not hard to find, since the soon-to-be free swimming jelly (or ephyra) is orange-red in color, and will even pulse a bit before detaching!
