Crustaceans

To exterminate a parktown prawn, you can use insecticides specifically designed for cockroaches or other suitable pests. Alternatively, you can place traps or bait stations in areas where they are commonly found. If you prefer a natural method, you can use diatomaceous earth, which can be sprinkled in their habitats to dehydrate and kill them. Always ensure to follow safety guidelines and consider consulting a pest control professional if the infestation is severe.

In crayfish, the walking legs and gills are attached because they share a common function of facilitating oxygen exchange. The movement of the walking legs helps to create a flow of water over the gills, allowing for oxygen to be absorbed and carbon dioxide to be released. This adaptation helps crayfish efficiently obtain oxygen from their aquatic environment.

A fossil that looks like a spiral or a ram's horn is called an ammonite. Ammonites were marine creatures that lived millions of years ago, and their distinctive spiral shape makes them easily recognizable in the fossil record.

In the animal kingdom, the African lungfish (Protopterus annectens) is known to be capable of staying dormant for up to three years during droughts by burrowing into mud.

Animals that eat snow crabs include certain species of fish, seabirds, and marine mammals. Predators such as cod, halibut, seals, and sea otters are known to feed on snow crabs in their natural habitats.

a distinct right and left side, allowing for better coordination and quicker responses to stimuli. This symmetry also helps with efficient movement and navigation in their environment.

Giant coconut crabs are omnivores, meaning they eat both plant and animal matter. They primarily feed on fruits, nuts, and vegetation but will also scavenge on carcasses or hunt small animals if the opportunity arises.

No, crayfish are primarily carnivores and typically feed on small insects, plants, algae, and decaying organic matter. Marsh marigolds are flowering plants that grow in wetland areas and are not a common food source for crayfish.

Krill swarms are easy 2 million strong. so imagine of a whale runs into a few swarms. The gorge themselves oin it, whales can eat 3 tons of krill a day! But also whales store alot of fat. A mother whale will taker her calves to safe water for the calf to grow strong and can so 5 months with out eating. If you are really interested you should watch planet earth shallow seas show.

The reason they can provide enough food is because whales eat so many of them (10-15 tons).

Almost all animals except sponges have either radial or bilateral symmetry. Sponges belong to the phylum Porifera, characterized by their lack of symmetry.

None. In crayfish, females become fertilized externally by mating with males. The male transfers sperm to the female, who then stores it until she is ready to fertilize her eggs.

A crayfish typically has two pairs of uropods. Uropods are appendages located at the end of the abdomen that help with swimming and stability in water.

The larval stage of mollusks is called a trochophore, which is a free-swimming, ciliated larva that eventually develops into the adult form. For annelids, the larval stage is called a trochophore or a nectochaete, which also metamorphoses into the adult form after a period of growth and development.

Chitinous teeth in crayfish help them grasp and manipulate food as they feed. These teeth are used to crush and grind food items, making it easier for crayfish to consume their prey. Additionally, chitinous teeth aid in the breakdown of food particles during digestion.

A uropod is used for swimming. Telson does the same thing.

Some lobsters have one claw larger than the other due to a phenomenon called bilateral gynandromorphy, where individuals have both male and female characteristics. This can result in one side having a larger claw typical of a male lobster, while the other side has a smaller claw like a female lobster. It is a rare occurrence in crustaceans.

Try some regular fish food. I used to have crayfish and I used to feed them fish food. When I fed the crayfish fish food I took them out of their tank and put them in a container with some water and fed them the fish food in the container. I did this so the the fish food won't make a mess in the tank. If the fish food floats on the top of the water stir it around and the food will fall to the bottom.

No, a millipede is not a crustacean. Millipedes are arthropods belonging to the class Diplopoda, while crustaceans belong to a different class called Malacostraca. Millipedes are characterized by having many legs and a cylindrical body, while crustaceans have segmented bodies and many possess a hard exoskeleton.

The ammonite fossil has a spiral shape similar to a ram's horn. Ammonites were marine creatures that lived millions of years ago and had coiled shells. These fossils are often found in sedimentary rocks and are prized by collectors for their intricate shapes.

Multi because they are living and breathing. Something like a rock would be single celled.

Brine shrimp are adapted to living in highly saline environments, so they require salt in their water to maintain proper bodily functions. Without the salt, their cells would not be able to regulate water balance correctly, leading to dehydration and eventual death.

A sea urchin has radial symmetry, meaning it is symmetrical around a central axis, like a wheel. This symmetry allows them to have multiple planes of symmetry passing through the central axis, giving them equal parts around the center.

Prawns are opportunistic feeders that typically consume a variety of plant and animal matter, making them omnivores. They scavenge for detritus on the ocean floor but also feed on smaller organisms like plankton and small fish.
