How do jellyfish take in nutrients?

A single cavity, the coelenteron, serves as a jellyfish’s stomach and intestine. Food that makes it into the jellyfish’s stomach is broken down by digestive enzymes produced by cells lining the inner body cavity. These cells help absorb and direct nutrients around the jellyfish body.

How do jellyfish take in food?

Some jellyfish have millions of very small stinging cells in their tentacles called nematocysts. These cells are used to capture food by injecting toxin into the prey.

What do jellyfish consume?

It’s a common question – What do Jellyfish eat? Most jellyfish love to be fed on live baby brine shrimp or frozen baby brine shrimp. In the wild, brine shrimp will commonly be a jellyfish’s diet.

How do jellyfish obtain energy?

Some jellyfish sit upside down on the bottom and have symbiotic algae (zooxanthellae) in their tissues, which photosynthesize, and so get much of their energy the way plants do.

How do sea jellies eat?

Jellies use their stinging cells to capture food, which mostly consists of zooplankton and other sea jellies. These stinging cells are primarily located along feeding tentacles and sometimes on the bell itself. The tentacles then pull the food into the gastrovascular cavity where it is digested.

How do jellyfish eat and poop?

It’s a lot like what happens in our own tummies after a meal. Any waste – that’s poop – then comes back through the mouth. That’s because jellyfish only have one opening into their stomach, so waste comes out the same opening as food goes in.

How does jellyfish metabolism work?

The jellyfish in Condon’s experiments released large quantities of carbon-rich organic matter–with 25- to 30-times more carbon than nitrogen. “This rapid metabolism shunted carbon toward respiration rather than production, reducing their potential to assimilate this material by 10 to 15 percent.”
