Cherry Shrimp (Neocaridina davidi) Dimensions & Drawings

What do crustaceans eat?

The diet of a crustacean depends on its size as well as species. Small terrestrial species typically eat matter from decaying organic matter. Parasitic crustaceans eat blood and skin materials from their host animal. Small aquatic crustaceans eat microscopic organisms, algae, and plankton while larger crustaceans eat snails, plants, and eggs of other marine life.

How do crustaceans breath?

Crustaceans breath oxygen and use the same respiratory system as fish by breathing oxygen through their gills. Gills are very similar to lungs, but the difference is that gills pull the oxygen from water and not air as lungs do.

Where do most crustaceans live?

Some crustacean species live in freshwater, while most prefer salt water and live in the ocean. Most crustacean species tend to live close to the shore. Specifically, woodlice and crabs live on land while prawns and shrimp in open water.

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.

How are freshwater animals adapted to their environment?

Freshwater animals adapt to their environment through gills that obtain oxygen and allow them to live in rivers and streams in which the water is cooler and has a higher oxygen level. Freshwater animals also need to swim fast to catch food and utilize their environment to create their home.

Why are freshwater animals going extinct?

Freshwater animals are going extinct due to the creation of man-made elements that block migration routes for fish and disrupt habitats. The water withdrawal for human use also shrinks and degrades habitats as well as the draining of wetlands for development depletes habitats. Other reasons include overexploitation, pollution, and global warming.

How can we protect freshwater fish?

We can protect freshwater fish by establishing multiple solutions. These solutions include restricting the construction of dams and establishing protected wetlands. Other solutions to protect freshwater fish are regulating water withdrawal for human use and incentive for farming businesses to reduce the use of pesticides.

What is the largest group of arthropods?

The largest group of arthropods are insects, and they can be distinguished from other arthropods through specific characteristics. These characteristics include them having 3 body regions, 3 pairs of legs, as well as a pair of antennae. Most insects also have the ability to fly, which other arthropods lack.

How do arthropods grow?

The arthropods grow through the process of forming new segments near their tail. The growth of an arthropod is very similar to the growth of annelids. Arthropods like mollusks have a tough exoskeleton, but this exoskeleton does not grow along with the rest of the animal and they have to shed their exoskeleton periodically.
