met her dream crab‚ a ten-legged green caped crab. They fell in love and had a beautiful crab wedding. The Generation one crustacean body’s phenotype was a plastic cup while the genotype was BB. The legs’ phenotypes were pearly white pipe cleaners and the genotype was ff. The crustacean had deep blue pom poms for eyes and the genotype was Ii. For antennae‚ the crustacean had soft qtips and the genotypes were Kk. One of Joy’s structural adaptations were vibrant purple stripes to help the crab camouflage

freshwater crustacean from the branchiopod class that is common to most ponds‚ lakes‚ pools‚ streams and springs around the world. The water flea‚ as it is sometimes referred to‚ is very small in size growing to a length of less than ¼ inch‚ it has a flat back‚ a rounded belly‚ black round eyes and a pair of antennae (Kindersley‚ 2006). The Daphnia have leaf-like appendages used in respiration‚ filter feeding and locomotion (Miller‚ 2010). Unfortunately‚ due to the size of these crustaceans they are

The goal of this project is to test whether alcohol and caffeine has an effect on heart rate‚ using the freshwater crustacean‚ Daphnia magna‚ as the experimental subject. For humans‚ alcohol works as a depressant‚ slowing down the heart rate of the consumer; caffeine works as a stimulant‚ increasing the heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart

Introduction: Crayfish also known as Procambarus clariia are classified as a decapod crustaceans related to lobsters‚ crabs‚ and shrimp. They breathe through the gills as they are aquatic animals but they can survive for short time outside the water. They have a hard‚ calcified exoskeleton that must be shed as they grow. In front of the first abdominal segment locates crayfish heart in the dorsal portion of cephalothorax. Crayfish are poikilothermic as their internal temperature is proportional

The Demospongiae sponge‚ Chondrocladia nicolae has a peculiar feeding process of being carnivorous they have proven to eat small crustaceans and having the distinctive orange color that is considered different from the other species under the Family Cladorhizidae.It has an anchorate isochelae with 3 teeth and spicules used to hook prey.The ‘skeleton of this species consists of axes and

These whales have also developed a special kind of hearing called echolocation‚ which helps it to find blowholes under the sheet of ice in the Arctic. Most beluga whales live on a diet of fish‚ crustaceans‚ squid‚ octopus‚ crabs‚ sand worms‚ and other small prey. They consume on average‚

control of movement; they also are the centres for the initiation of complex behaviour. The deutocerebrum contains the association centres for the first antennae. The posterior tritocerebrum contains association neuropils for the second antennae (of crustaceans) and gives rise to nerves that innervate the mouthparts and the anterior digestive canal. The latter constitute the stomatogastric system‚ which regulates the intake of food and the movement of the gut necessary for digestion. This system bears

Crayfish – also called crawfish‚ crawdads‚ freshwater lobsters‚ or mudbugs – are freshwater crustaceans resembling small lobsters‚ to which they are related; taxonomically‚ they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills and are found in bodies of water that do not freeze to the bottom. They are mostly found in brooks and streams where there is fresh water running‚ and which have shelter against predators. Most crayfish cannot tolerate polluted
