What does a bloody-belly comb jelly eat?
Many of the deep-sea animals the bloody-belly comb jelly preys upon can bioluminesce, or create their own light. The translucent predator needs to conceal its stomach—or risk its most recent meal lighting it up from the inside out and alerting potential predators to its whereabouts.
What is unique about comb jellies?
Comb jellies are named for their unique feature: plates of giant fused cilia, known as combs, which run in eight rows up and down their bodies. The combs act like tiny oars, propelling the comb jelly through the water.
How long do comb jellies live?
Small parts of these animals break off and grow into adults. Little is known about most species, but the lifespan of those that have been studied ranges from less than a month to three years.
Do comb jellies eat each other?
Comb jellies are cannibals Comb jellies will eat other comb jellies that are larger than themselves. They do this by biting off chunks of them with special cilia structures in their mouths. However, they first prefer to eat plankton, zooplankton, crustaceans and small fish.
How many comb jellies are left?
There are currently 200 known, or described, comb jelly species. With the COI gene sequences hinting that some of these may be more than one genetically distinct species, that count is likely to grow three- or even fourfold.
Do comb jelly have eyes?
They have other proteins called opsins that detect light, even though comb jellies lack eyes, the team reports today in BMC Biology.
Do comb jellies have brains?
Comb Jellies (belonging to the phylum Ctenophora) are fascinating; they can regenerate not only body parts, but also their brains. These organisms show that there is more than one way of making a nervous system.

How do jellyfish give birth?
There are two main ways that jellyfish reproduce and if the conditions are favourable they can do this daily. There are a few jellyfish species that receive sperm through their mouths to fertilise eggs inside the body cavity, but most jellyfish just release sperm or eggs directly into the water.
Do comb jellies eat their babies?
The study concludes that the comb jellies in the wild eat their larvae when their own prey run out, making the population explosion in August a way of “building up resources for the winter,” Larson tells Science News’ Erin Garcia de Jesus.
Does jellyfish have gender?
Jellyfish are usually either male or female (with occasional hermaphrodites). In most cases, adults release sperm and eggs into the surrounding water, where the unprotected eggs are fertilized and develop into larvae.
Why does the bloody-belly comb jelly have a red stomach?
The blood-red stomach disguises the glowing prey inside. Many of the deep-sea animals the bloody-belly comb jelly preys upon can bioluminesce, or create their own light. The translucent predator needs to conceal its stomach—or risk its most recent meal lighting it up from the inside out and alerting potential predators to its whereabouts.
How does the bloody belly comb jelly protect itself from predators?
Many of the deep-sea animals the bloody-belly comb jelly preys upon can bioluminesce, or create their own light. The translucent predator needs to conceal its stomach—or risk its most recent meal lighting it up from the inside out and alerting potential predators to its whereabouts.
Who discovered the bloody-belly comb jelly?
George Matsumoto, the marine biologist at the Monterey Bay Aquarium Research Institute (MBARI) who discovered the bloody-belly comb jelly in 2003, told the Mercury News that he didn’t think it could ever be displayed as it would melt when collected. “I never had an intact specimen. I never saw it under a microscope,” he said.
Why is it called red red comb jelly?
Red is nearly invisible in the deep sea, so the vibrant crimson that gives this comb jelly its name is actually helping it hide from its predators. Bloody-belly comb jellies are ctenophores, not true jellies.
