Where is the Gaster on an ant?
The gaster is the bulbous posterior portion of the metasoma found in hymenopterans of the suborder Apocrita (bees, wasps and ants). This begins with abdominal segment III on most ants, but some make a constricted postpetiole out of segment III, in which case the gaster begins with abdominal segment IV.
What is the metasoma on a scorpion?
Scorpions have a segmented appendage on their back end called a metasoma, used to sting, hunt prey, mate, dig and defecate. Its anus is also on the metasoma, as are its intestines and ventral nerve cord.
How many segments are found in the abdomen of a scorpion?

What is the difference between the Metasoma and the Mesosoma?
The metasoma is the posterior part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the mesosoma. … In scorpions, the metasoma is the tail. In other chelicerates, such as spiders, the mesosoma is fused with the metasoma to form the opisthosoma.
What are the Tagmata sections of an insect?
Insects first evolved 300 million years ago. Their body is divided into three tagmata: head, thorax, abdomen.
Do ants have blood?
The short answer is ants have something similar to blood, but scientists call it “haemolymph”. … Your blood is red because it contains lots of tiny, tiny packages called “red blood cells”, which carry oxygen around your body.

Do ants have spinal cords?
The nervous system of ants consists of a long nerve cord that also runs from head to rear with branches leading to the parts of the body, kind of like a human spinal cord. An ant has a petiole connecting the thorax to the abdomen.

The scorpion’s four pairs of legs are attached to the prosoma as well.
How do scorpions reproduce?

What is an interesting fact about scorpions?
Scorpions are arthropods, they have eight legs, two pedipalps, and a tail with a venom-injecting barb. Scorpions have two venom glands that produce venom used in hunting and self defense. Scorpions do not have bones instead they have an exoskeleton made of chitin, which is similar to the shell of a shrimp.
Do crustaceans have Pedipalps?
Pedipalps are traditionally thought to be homologous with mandibles in crustaceans and insects, although more recent studies (e.g. using Hox genes) suggest they are probably homologous with the crustacean second antennae.
Do spiders antennae?
Spiders, and other species in the Arachnida group, have eight legs with only two body parts as well as eight eyes. A spider’s head and thorax are fused while their abdomen is not segmented. Spiders also do not have distinct wings or antennae like insects.
What is the function of tagmata?
Like most insects, adult lepidopterans have three distinct body segments, or tagmata—the head, the thorax, and the abdomen—each with special functions. The head bears the main sensory organs and those of feeding and ingestion. The thorax is chiefly concerned with locomotion.
Do all arthropods have tagmata?
Each group of arthropods has a characteristic set of tagmata; for example, insects have three main tagmata, while spiders have only two.

Are ants brains or hearts?
While they lack a proper heart, they do have a pumping organ called a dorsal aorta that pumps blood towards the head, achieving a small current. Unlike blood, hemolymph does not carry oxygen; so, ants – and all other insects – lack lungs entirely. Instead, ants breathe through a set of tubes called tracheae.
Do ants eat butter?

Do insects have hearts?

Do ants sleep?
YES, THEY DO – but not in the sense we understand sleep. Research conducted by James and Cottell into sleep patterns of insects (1983) showed that ants have a cyclical pattern of resting periods which each nest as a group observes, lasting around eight minutes in any 12-hour period.
