How do comb jellies reproduce?
Spawning occurs at night when water temperatures warm to 66-73 degrees. Comb jellies have both male and female reproductive organs and can fertilize themselves. Each comb jelly releases about 8,000 eggs per spawn. ... Young are able to reproduce 13 days after hatching.
Do comb jellies reproduce sexually?
Comb Jellies
Most are hermaphrodites, with individuals carrying both male and female sexual organs. After they grow to a certain size, they release eggs and sperm daily, which drift in the water for minutes to hours until they are able to fertilize and grow into new comb jellies.
Can you touch a comb jelly?
Unlike jellyfish, comb jellies don't sting. Instead, they use unique sticky cells—colloblasts—to catch their prey. Since they don't possess stinging cells, they can be safely touched. In fact, you can also swim around with them!
What is a warty comb jelly?
Mnemiopsis leidyi, the warty comb jelly or sea walnut, is a species of tentaculate ctenophore (comb jelly). It is native to western Atlantic coastal waters, but has become established as an invasive species in European and western Asian regions.
Can comb jellies sting?
Many comb jellies have a single pair of tentacles (often each tentacle is branched, giving the illusion of many tentacles) that they use like fishing lines to catch prey. They are armed with sticky cells (colloblasts) and unlike jellyfish, the tentacles of comb jellies don't sting.
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.
Can jellyfish reproduce sexually?

How is a jellyfish immortal?
Jellyfish, also known as medusae, then bud off these polyps and continue their life in a free-swimming form, eventually becoming sexually mature. ... Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal, although in practice individuals can still die.
What does a comb jelly mimic?
D. The comb jelly is a marine invertebrate that swims by beating rows of cilia that resemble combs. ... Jellyfish are cnidarians, while comb jellies belong to the phylum ctenophora.
How do jellyfish mate?
In this species, a male will use his tentacles to grab a female's tentacles; he will then drag her around for a while before pulling her in close to him. Next, he will produce and release a spermatophore (sperm packet), and use his tentacles to pass it to one of the female's tentacles.
Where does the Bloodybelly comb jelly live?
Lampocteis is a monotypic genus of comb jellies, the only genus in family Lampoctenidae. The sole species in this new genus is Lampocteis cruentiventer, the bloodybelly comb jelly. This ctenophore was first collected in the Pacific Ocean off the coast of San Diego, California, in 1979.
How do Bloodybelly 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 are the predators of a comb jelly?
Natural predators of comb jellies include sea turtles, fishes, marine mammals, and even other comb jellies. Comb jellies use different feeding strategies based on the species and its habitat, but most are known as passive feeders.
How do comb jellies poop?
Because comb jellies are translucent, the prey can be seen as it circulates through a network of canals lacing the jellies' bodies. Fast-forward, and 2 to 3 hours later, indigestible particles exit through the pores on the rear end.
