So how do they do it?Although they have no central brain, the jellyfish do have a nervous system(神经系统). It's made of four main parts that look like hanging strings(绳子).Each part has about 1,000 neurons(神经元) and six“simple” eyes. This lets them see and avoid things and...
How do fish help coral reefs? How do ecosystem services benefit humans? How can bacteria be helpful? How do pesticides affect humans? Explain. How does ecology help improve the environment? Why are reptiles and amphibians important to the environment?
How did the arthropod exoskeleton help them dominate the ocean? What kinds of jellyfish are there? How is an amoeba adapted to live in freshwater? How do animals in the abyssal zone survive? What is the taxonomy of a jellyfish? How do frogs adapt to their habitat?
Jellyfish are carnivores -- they eat other animals. Smaller jellyfish eat algae and other tiny plankton called zooplankton. Larger jellyfish eat crustaceans and other bigger aquatic animals. They don't seek out people to attack -- their nervous system is too simple to do that. Their sting is...
Their bodies evaporate into the air and essentially disappear within a few hours after washing up onshore. So how long can an animal like this stay alive? Let’s dive into the jellyfish lifespan. How Long Do Jellyfish Live? Some jellyfish are immortal. ...
Already stressed by habitat destruction, decades of poaching, and climate change, sea turtles are at particular risk from plastic bags, as they oftenmistake them for jellyfish– a popular food for many sea turtle species. In fact, researchers from the University of Queensland recently determined ...
Grit, a senior postdoc studying jellyfish and freshwater snails, talked about expeditions as a possibility to “see how things are,” namely to see the landscapes the samples originate from. Expeditions were also understood as an important opportunity to create a relationship with the place under...
Also, those two species are only a small sampling of mimic octopuses' masks. Experts also think they've witnessed up to 13 different species imitations, including jellyfish, anemone and mantis shrimp, but they have yet to confirm them all [source: Hanlon, Conroy and Forsythe]. Even more ...
Dolphins are known to eat a variety of foods, including crabs, fish, grass and even jellyfish. But what’s even more interesting is how they have evolved to eat their food. Some dolphins in groups have been known to form a sort of feeding network, where they work together to catch and...
How do jellyfish survive in their habitat? How has the phylum Sphenophyta adapted to survive on land? How do fish survive in the abyssal zone? How are nekton adapted to life in the sea? What are some characteristics for organisms living in the mesopelagic zone?
