Crustaceans

The zygote of a crayfish with a diploid number of 112 chromosomes would contain 56 chromosomes. This is because the zygote receives one copy of each chromosome from each parent, resulting in half the number of chromosomes of the diploid number.

To pick up a crawdad without getting pinched, approach it from behind and grasp it firmly but gently around the body between the claws. Avoid grabbing the claws or the tail to prevent being pinched. Holding them securely and steadily will usually prevent them from pinching you.

You may be referring to a millipede, which is a long, slender, worm-like animal with many pairs of legs. Millipedes can have anywhere from 30 to 400 pairs of legs, and they are known for their distinctive cylindrical body shape and segmented exoskeleton. These creatures are not insects, but belong to the class Diplopoda.

A cheliped is a specialized claw-bearing appendage found in crustaceans such as crabs and lobsters. It is used for capturing and handling food, defense, and grooming. The term "cheliped" comes from the Greek words "chela," meaning claw, and "pous," meaning foot.

There is no difference between an antennule and antennae. An antennule is just a small antennae. Antennules are basically the same, but just in size that they vary. They both have the same purposes, the antennae is the plural form of saying the bigger antenna.

A sunflower is a good example of an object that illustrates radial symmetry. The seeds of the sunflower radiate outwards from the center, creating a symmetrical pattern that is repeated throughout the entire flower.

Members of the Phylum Ciliophora move using cilia, which are short, hair-like structures covering their surface. These cilia beat in coordinated patterns to create movement by either propelling the organism through the water or generating feeding currents to capture food particles.

Crustaceans have two pairs of antenne, which can be found on the first two segments of the head. These antenna are often used as sensory units, but can also be used for things such as swimming.

This is kind of tricky. Krill are actually small shrimp, but capable of purposeful swimming. Plankton, by definition, are all the little things in the water, some plants, some animals, that are not capable of purposeful swimming. That is, even if they swim a little, it is not enough to move them significantly from place to place relative to ocean currents. Larval krill would be part of the planktonic community, as would the larvae of many marine creatures. But adult krill are not plankton.

Size comparison: Krill can grow to over 20cm in length and feed primarily on the mostly microscopic plankton.

Crustaceans grow by molting, which is the process of shedding their exoskeleton in order to grow larger. When they molt, they emerge with a soft exoskeleton that eventually hardens. This process allows them to accommodate their increasing size as they continue to grow.

Prawns and shirmps belong to the phylum arthropoda and organism with backbones belong to the phylum chordata. Therefore prawns, shrimps (crustaceans) and insects do not have a backbone.

Krill are omnivores, as they feed on both plants and animals. Their diet primarily consists of phytoplankton, zooplankton, and small fish.

Bilateral symmetry allows for the animal to have directed movement, which can help when searching for food or escaping predators. Also, it allows for quicker and precise response to stimulation, since the nervous system is cephalized and much more complex than in organisms without bilateral symmetry.

Crawdads in the Pacific Northwest are usually active in the evenings starting in late June all the way till about October. The water might be dangerous this time of year, but give it a couple weeks and it will be just right.

No, prawns are not herbivores. They are omnivores, meaning they eat both plant matter and other animals. In the wild, prawns typically feed on small organisms such as plankton, algae, and small invertebrates.

A crayfish has a pair of mandibles and several pairs of maxillipeds in its mouth that help it to crush food. The mandibles are like small pincers, while the maxillipeds are used to handle and manipulate food before it is eaten.

Crustaceans such as Lobsters and Crabs have exoskeletons. Check out the "Yeti Crab" sometime when you have time: It was only discovered in March of 2005 and it does look strange.
armadillo, lobsters, crayfish, scorpion
Insects, spiders and crustaceans have exoskeletons.

No, krill are not asexual reproducers. They reproduce sexually, with females laying eggs that are fertilized by males.

Insects have bilateral symmetry because if they had radial symmetry, they would have to be perfectly round. Bilateral symmetry is just when you cut something with a line of symmetry down the middle and both sides are symmetrical.

The fresh-water prawn will eat just about anything. In nature it will eat pieces of worms, snails, clams, fish, pieces of rice, wheat, beans, nuts,etc

Prawns are omnivores and they typically eat algae, plankton, small fish, and decaying matter. They are scavengers and will also feed on various detritus and organic debris found in their environment. In captivity, they can be fed commercial shrimp pellets or flakes as well.

The word ''Arthropoda' means ''joint-legged'' and both creatures are that. Also they have exoskeletons and open circulatory systems along with a few other common characteristics. Take a course in Invertebrate zoology.

Prawns support biodiversity by serving as a food source for many predators and contributing to ecosystem balance and nutrient cycling. They can also increase biodiversity by creating habitat structure within their environment. Additionally, prawns themselves exhibit diversity within their own species in terms of physical characteristics, behavior, and habitat preferences.

Antennae are sensory appendages that detect chemicals and vibrations, chelipeds are specialized for grasping and defense, walking legs are for mobility on land, and swimmerets are used for swimming and reproduction. Together, they all play important roles in the overall functioning and survival of the crustacean.
