CATDOLL : CATDOLL: Are shrimps fish or insects?

1. Is shrimp a fish or an insect?

Shrimp is not a fish or insect because it belongs to the subphylum Crustacea of ​​the phylum Arthropoda invertebrates, which is different from the classification of fish and insects. The body structure of shrimp is very different from that of fish and insects. For example, shrimp has a shell and a pair of large claws, while fish and insects do not have these characteristics. Shrimp is a very popular seafood with high nutritional value. It contains a lot of protein and various vitamins and minerals, which are beneficial to human health. Shrimp is also an important aquaculture industry. The global shrimp production is increasing and is widely used in food and pharmaceutical fields.

2. Are crabs fish or insects?

Fish are vertebrates, crabs are invertebrates, Animalia, Arthropoda, Crustacea, Decapoda, Reptilia. Crabs are crustaceans, and their bodies are protected by hard shells. Crabs breathe through gills. In biological taxonomy, crabs are the same kind of animals as shrimps, lobsters, and hermit crabs. Most species of crabs live in the sea or near the sea, of course, there are also some crabs that live in fresh water or on land. They rely on female crabs to give birth to baby crabs, and each time the female crab will lay a lot of eggs, the number can reach millions or more. Crabs rely on the geomagnetic field to determine the direction.

3. Is a lobster an insect or a fish?

Shrimp is neither fish nor insects, but a kind of arthropod that lives in water and belongs to the class of arthropod crustaceans.

Shrimp is an arthropod that lives in water. It belongs to the arthropod crustacean class and there are many species, including Antarctic red shrimp, green shrimp, river shrimp, grass shrimp, prawn, prawn, lobster, etc. Shrimp has high nutritional value for diet and can be steamed, fried, etc., and can be used as a Chinese medicinal material.

Fish are the oldest vertebrates. Some hybrids with different numbers of chromosomes are still fertile. They live in almost all aquatic environments on Earth, from freshwater lakes and rivers to saltwater seas and oceans. Fish are cold-blooded vertebrates that live in water all year round, breathe with gills, and use fins to assist body balance and movement. According to statistics from the late Canadian scholars, there are 24,618 species of living fish in the world, accounting for more than half of the named vertebrates, and new species of fish are constantly being discovered, with an average of about 150 species per year. In more than ten years, more than 1,500 species should have been added. At present, there are about 32,100 named fish species in the world. It is the most primitive and common group in the subphylum of vertebrates.

Insects: Insects are a general term for invertebrates such as the class Insecta and the class Arachnida. In a narrow sense, insects refer to animals of the class Insecta of the phylum Arthropoda in the animal kingdom. The general class Hexapoda (including the four classes Prototail, Collembola, Diplodocus, and Insecta) are all referred to as insects. The largest group of all organisms in terms of species and number, it is the most prosperous animal in the world, with more than 1 million species discovered. Its basic characteristics are that the body has three sections: head, thorax, and abdomen, two pairs of wings and three pairs of legs; a pair of antennae grows on the head, and the skeleton is wrapped outside the body; the morphology changes throughout life, and it is a prosperous family all over the world. However, not all Arthropoda are insects in the narrow sense. For example, woodlice belong to the suborder Woodlice of the class Crustacea of ​​the phylum Arthropoda, but woodlice do not belong to insects, because in terms of the narrow definition of insects alone, insects refer to invertebrates of the class Insecta and Arachnida, so "insects" like this that do not belong to the class Insecta and Arachnida are insects in the broad sense rather than in the narrow sense.

In a broad sense, "worm" can be used to refer to certain organisms in general, not limited to the phylum Arthropoda. For example, flagellates, sarcoptes, and ciliates in the phylum Protozoa; turbellaria, tapeworms, and flukes in the phylum Platyhelminthes. There are also planula larvae in the juvenile stage of coelenterates, but they are not insects.

4. Are snails animals or insects?

Snails refer to all terrestrial species of gastropods, which include animals of many different families and genera. Snails are not insects. Insects specifically refer to animals with two antennae, six legs and two pairs of wings.

5. Is shrimp a type of fish?

Shrimp is not a fish. Shrimp is an arthropod that lives in water. It belongs to the arthropod crustacean. Shrimp is a swimming animal of the subphylum Crustacea, the order Decapoda, and there are nearly 2,000 species, most of which live in rivers and lakes. There are many species, including Antarctic red shrimp, green shrimp, river shrimp, grass shrimp, prawn, prawn, lobster, etc. Shrimp is not a fish. However, shrimp and fish have an inseparable relationship. There is a saying: big fish eat small fish, small fish eat shrimp

6. Is a butterfly an animal or an insect?

Butterflies are insects. Known as flying flowers, butterflies are very beautiful insects. Most butterflies are medium to large in size, with a wingspan of 15-260 mm and two pairs of membranous wings. The body is long and cylindrical, divided into three parts: head, thorax, and abdomen. The body and wing membranes are covered with scales and hairs, forming various color patterns.

The different living habits of adult butterflies and the changes in the structure of their external genitalia ensure that different species do not hybridize with each other. Before mating, most butterflies go through a period of courtship flight, and some species need a large space for their nuptial flight.

7. Is the cuckoo a bird or an insect?

Belongs to poultry.

Cuckoo is the general name for birds of the family Cuckoo. Common ones include the Great Cuckoo, the Three-note Cuckoo and the Four-note Cuckoo. The Great Cuckoo's call sounds like "cuckoo, cuckoo", so it is also called the cuckoo bird; the Three-note Cuckoo's call sounds like "Mi Guiyang", so some places call it Mi Guiyang; the Four-note Cuckoo is also called the Cuckoo Bird, and its call sounds like "Quickly harvest wheat" or "Harvest wheat and harvest grain". Cuckoo feeds on insects and is a famous forest bird. For example, pine caterpillars and poisonous moths are not eaten by other birds, but they are delicious delicacies for cuckoos.

Most live in tropical and temperate forests. About two-thirds of cuckoos, including all North American species, build nests and raise their own young; only about one-third of cuckoos raise their young parasitically.

8. Are snakes insects or mammals?

Snakes are neither insects nor beasts.

Snake is the general name for the suborder Serpentes of the order Squamata of the class Reptiles

Snakes are reptiles. They have long and slender bodies, and their limbs have long since degenerated. They belong to the order Serpentes, class Reptilia. Long ago, snakes had legs, but as time went by, their legs degenerated. They rely on the scales on their abdomens to glide, and they are faster and more flexible than their legs. Snakes have poor eyesight and hearing, but their tongues are very sensitive.

Neither birds, beasts, or fish are insects. Beasts refer to mammals. The concept of insects is very broad. In zoology, insects are invertebrates, while snakes are vertebrates. Therefore, in zoology, snakes are not insects either.

9. Are snakes considered insects?

Snakes are not insects. They are a type of animal belonging to the phylum Chordata and class Reptilia. They have an elongated body consisting of the head, trunk, and tail. They have no limbs or claw-like remains of hind limbs on both sides of the transverse cloaca of lower snakes. They are covered with scales and have heads of various shapes. Their nostrils are located on the sides of their snouts, but those of sea snakes that live in the sea for their entire lives are located on the back of their snouts.

Cave life:

Most of the snakes that live in caves are relatively primitive and low-level small and medium-sized snakes. As a result of adapting to cave life, their anatomical characteristics are: small head, strong skull connection; small mouth, slightly protruding in front of the mouth, underdeveloped eyes; short tail; undifferentiated or underdeveloped abdominal scales. Such as blind snakes and flaming snakes. Cave-dwelling snakes mostly come to the ground at night or in dark weather, and are all non-venomous snakes.

10. Is Dactylopidae a protozoan or a worm?

Dactylorhiza is a parasite belonging to the genus Dactylorhiza. It is a small monogenean trematode. The adult worm is flat, usually oblong, less than 2 mm long, and milky white. When it moves, it moves like an inchworm, and its expansion and contraction can be seen with the naked eye.

It is mainly spread by eggs and larvae. It is prevalent in late spring and early summer, and the suitable temperature is 20-25℃. When it is parasitic in large numbers, the diseased fish will have increased mucus in the gill filaments, and the gill filaments will be swollen, pale, and anemic. The gill covers of the diseased fish will open, breathing will be difficult, swimming slowly and dying. It mainly harms silver carp, bighead carp and grass carp, and is often seen when checking grass carp in the market.
