Amazing Purple Jelly Sighting in the Deep Sea

The Helm Lab Blog

I live for moments like this. Things like this make the long nights editing grant proposals, the paper rejections, the failed experiments all worth it. To me, the best part of science is stuff like this: seeing something that completely takes my breath away. Even after studying animals like this for the last five years, this video has me in awe. The animal captured in this footage, simply put, is stunning:

This video was collected as part of the Nautilus Live expedition, a broadcast ocean exploration that anyone with internet access can be part of. The expedition is being headed by Dr. Robert Ballard, who famously discovered the wreck of the Titanic. But to me, the video above captures something much more rare and mysterious than any sunken ship.

This strange animal is a siphonophore, a relative of jellyfish. The most famous (infamous?) siphonophore is the portuguese man-of-war, but there are many species that live in the deep and are only seen on rare…

Outta-sight Jelly Babies Discovered Under Black Light

The Helm Lab Blog

So, the flower hat jellyfish pretty much looks like someone painted it while tripping on acid. It doesn’t just have tentacles on the edges, no way man, its got a tentacle party going all up over its body. It doesn’t just have pink and purple colors, it’s got blue and orange and green all over too (did I mention it glows?) And it doesn’t just look trippy with its little highlighter fro, it acts weird too. Unlike most jellies, flower hats spend most of their day just chillin’ on plants or pebbles or whatever really, only interested in swimming around for munchies once the sun goes down. They’re found only around southern Japan, and aquarists pay a premium for a chance to put them on display. That’s because the weirdest part of the flower hat jelly is this: no one had ever seen a baby flower hat before, until now.

Tip: Knowing How Much to Feed your Jellyfish

Hungry Jellyfish with Empty Stomachs

It’s hard to regulate just how much food to feed your fish sometimes.  You don’t want to over feed them or under feed them.  But, how do you know if your jellyfish are getting enough to eat each day????? If only you could see just how full they were.  Hard to do with fish, BUT….you have jellyfish!!! They’re transparent!

You can see right through them & see their stomachs!  This is the best way to know if you’re feeding enough each day to keep them healthy and growing.

One of the most common problems when keeping jellyfish as pets is keeping them nutritionally fulfilled. Most folks are not sure just how much to feed to keep their jellyfish healthy.  Jellies are passive feeders and need more food than you think. They quickly become lethargic and thin if they aren’t getting enough good food to eat. So, if you start out not feeding enough nutritional food, your jellyfish will start to wither and shrink.

The picture below represents moon jellyfish that are waiting for a meal. Empty stomachs!

The picture below demonstrates what your jellyfish should look like about 45 minutes after feeding them.

Full Stomachs! Happy Jellyfish!

Their stomachs should be nice and full like this at least once a day, with nutritionally sound food for jellyfish.


A word about vacations, weekends & days off from feeding….

If your jellyfish are healthy and being fed normally and on a regular basis with nutritional jellyfish food, then you can safely get out of town for the weekend.  They will be fine given they have full stomachs 5 days out of 7
