What other animals have endoskeletons?

Mammals, reptiles, birds, fish and amphibians are vertebrates with endoskeletons (skeletons inside their bodies). Their skeletons provide support and protection and help them to move. Insects, spiders and shellfish are some of the invertebrates that have exoskeletons.

Which animal does not have bones and its body is covered with a hard outer skeleton?

Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.

What animal does not have a bony skeleton?

Slugs, worms and jellyfish are examples of animals without a bony skeleton. Pupils learn that all animals with a bony skeleton have a backbone and that these animals are called vertebrates. They also learn that animals without a bony skeleton or a backbone are called invertebrates (a cut, sort and paste activity).

What animals have a hydrostatic skeleton?

Hydrostatic skeletons are very common in invertebrates. A common example is the earthworm. Also, hydrostatic nature is common in marine life such as jelly fish, starfish, and sea anemones. Earthworms have rings of muscles that are filled with fluid, making their entire body hydrostatic.

What type of skeleton does a zebra have?

endoskeleton
These animals have an endoskeleton. Initially, all endoskeletons were made of cartilage, which is a dense rubbery type of tissue.

What are three animals that have an exoskeleton?

Examples of animals with exoskeletons include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters, as well as the shells of certain sponges and the various groups of shelled molluscs, including those of snails, clams, tusk shells, chitons and nautilus.

Are teeth skeleton?

Teeth are considered part of the skeleton system even though they are not bone. Teeth are the strongest substance in your body being made up of enamel and dentin. There are 32 teeth in an adult, and 28 in children. In looking at bone and teeth, there can and is genetic variation between individuals.

What are the five vertebrate groups?

The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds. Show examples of these groups and explain the characteristics that make one different from another.

What kind of animal has a shell on its body?

When we think of animals with shells, our first thought might be the turtle. Their shell is not only part of the turtle’s body, but part of a larger cultural identity and historical mythology. However, there are many types of animals with shells.

What are the different types of fluid in the body?

The fluids of the body may be classified into two main divisions: the fluid within cells ( intracellular fluid) and the fluid outside the cell ( extracellular fluid ). The extracellular fluid can be further divided into interstitial fluid, plasma, lymph, cerebrospinal fluid, and milk (in mammals).

How are animals able to survive on almost no water?

Downsizing their hearts and livers by 20 and 45 percent, respectively, allows them to breathe less. Taking fewer breaths means less water lost to respiratory evaporation. This article was originally published in the March/April 2017 issue of Popular Science, under the title “Moisture Misers.”

Which is an example of an animal’s excretory organ?

In the phylum Mollusca (clams, snails, oysters, mollusks, octopuses, and squids), gills add another more efficient channel for waste disposal. A heart increases the rate of flow in the circulatory system and speeds the transport of wastes to the gills. An excretory, kidneylike organ removes metabolic wastes from…

What can be found in a body fluid sample?

Body fluids can be analyzed in medical laboratory in order to find microbes, inflammation, cancers, etc. Clinical samples are generally defined as non-infectious human or animal materials including blood, saliva, excreta, body tissue and tissue fluids, and also FDA-approved pharmaceuticals that are blood products.

Why do animals with bilateral symmetry live in water?

Animals with bilateral symmetry that live in water tend to have a fusiform shape: this is a tubular shaped body that is tapered at both ends. This shape decreases the drag on the body as it moves through water and allows the animal to swim at high speeds.
