00:11they're spineless brainless and absolutely mesmerizing to watch I am of course talking
00:20about the jellyfish a marine marvel that captivates thousands of visitors every year
00:25here at the Audubon Aquarium in New Orleans but what does it take to look after over 300 jellyfish
00:31what do they eat and with such a simple body plan with such few organs how do they eat to
00:38answer a
00:38few of these questions I think we're gonna need a little bit of help this is Beth Fershaw director
00:43of husbandry and a bit of a jellyfish nerd let's see if she can shed some light on our jelly
00:49questions
00:51so Beth how many actual species of jellyfish do you have here at the aquarium we have the moon
00:56jelly which is one of my favorites the egg yolk jelly which is perfect for mornings yes and we
01:01have the Pacific stinging nettle which is right behind us these ones right here beautiful now
01:06with so many different species I'm guessing that they eat a bunch of different diets right so how
01:10do you go about feeding them well the majority of them eat plankton and we actually hatch a type of
01:16plankton baby brine shrimp right here at Audubon from diet tiny tiny tiny little cysts or eggs we
01:22hatch it right here by the thousands actually probably by the millions because they're really
01:27tiny but some of the jellies need a little bit more to their diet and they're actually medusivores they
01:34actually are cannibals they eat other jellies so we have a little extra hanging around how does a
01:44jellyfish actually eat well they've got those really long tentacles and on those tentacles are
01:50special singing cells that when food comes floating by and it triggers those stinging cells a little
01:57needle goes through jabs that food item like a baby brine shrimp and pulls it ever so slowly into the
02:04mouth and the mouth is located on the bottom of the bell or medusa right in the center now you
02:10were
02:11telling me something earlier and kids I think you're going to enjoy this one something about
02:15jellyfish poo can you explain that a little bit more in depth well their mouth is also where they
02:20poo so in order to eat more they have to poo out what they've already digested wow she wasn't kidding
02:30well I guess it makes it easier to see which jellyfish have eaten and which jellyfish are still hungry I
02:36had no idea how complex these seemingly simple aquatic animals are between their mesmerizing locomotion and
02:45their should we say unique eating and excreting technique it's no wonder that Beth has devoted her
02:51life to studying these incredible creatures
