Black Sea Nettle Jellyfish (Chrysaora achlyos) Dimensions & Drawings

What is a group of jellyfish called?

A group of jellyfish is called a smack. A smack is also the term used to describe a slap or blow that is given by the hand either usually as a reaction. The term smack is used for a group of jellyfish as it describes what it feels like when someone is among jellyfish.

What do jellyfish eat?

Jellyfish usually eat whatever food they find as they swim through water and can fit in their mouth which includes shrimp, krill, and small fish. As a result of this process, jellyfish are considered ‘passive’ feeders since they are not actively hunting or looking for food.

How do jellyfish reproduce?

Jellyfish reproduce in 2 different ways depending on their current body form since they embody 2 different body forms throughout their lifespan, the medusa and polyps. Polyps can reproduce through asexual budding and the medusa body form reproduces through spawn eggs and sperm to reproduce sexually.

What do cnidarians use for defense?

Cnidarians are aquatic animals with two body forms (the ectoderm and endoderm separated by a mesoglea). To capture prey or even defend themselves, cnidarians have unique and well-developed specialized cells in their mouths and tentacles for stinging attackers. These cells, called cnidocytes, have toxins that are released when their body is touched.

How do cnidarians reproduce?

Sexual and asexual reproduction are the forms of reproduction seen among cnidarians. Besides, some are hermaphrodites — capable of producing both eggs and sperms at the same time. However, asexual reproduction is the most common in this species. Sexual reproduction may occur only in one phase of a cnidarian’s life cycle.

Do cnidarians have brains?

What cnidarians have are diffuse nets of nerves that coordinate messages around their bodies. Research shows that these nets of nerves are just as complex as that of human beings. In addition, some like jellyfish, have no heart or eyes. Most cnidarians also have a transparent body covered in a chitinous exoskeleton.

How do invertebrates protect their soft bodies?

Invertebrates can effectively protect their soft bodies through an outer hard casing that is referred to as the exoskeleton. Invertebrates like spiders, crustaceans, and insects have their exoskeletons made through sections of jointed legs. Others like mollusks like snails and clams have a hard shell in which they can hide when danger is present.

What is the difference between an invertebrate and a vertebrate?

The difference between an invertebrate and a vertebrate is that invertebrates have no backbones while vertebrates have a developed internal skeleton with cartilage and bones as well as a developed brain that is protected by a skull. Vertebrates also cannot make their food, while invertebrates make their food.

Why are invertebrates important?

Invertebrates are important because like bees they help with pollination, as well as help clear and clean up the environment. Invertebrates are also important because they are soil aerators and creators as they help grow food crops. They also provide eco-system balance and serve as food for other species within the food chain.

What do marine animals need to survive?

Factors that marine animals need to survive include bioluminescence which is when animals make their own light and helps them communicate and scare predators. Constant light, pressure, temperature, and food are factors needed to remain stable and help marine animals evolve to survive. Marine animals that live within the deep sea can withstand the cold.

Why do we need to protect marine life?

Humans need to protect marine life because our actions and lifestyles have a direct impact on the ocean. We need to protect marine life and provide a safe and healthy environment that is not impacted by overfishing, climate change, pollution, habitat destruction, invasive species, and other forms of human exploitation.
