In what way are reptiles fish and amphibians similar?

What is the difference between fish and reptile?

Difference Between Fish and Reptiles. A fish is an animal that lives only in the water, whereas a reptile lives in both land and water. A fish is an aquatic vertebrate that is cold blooded or ectothermic.

Do reptiles&fish have scales?

Most reptiles and fish bear scaly outer coverings, although exceptions exist in both categories. Fish have scales that arise from dermal — bony — tissue and have a somewhat similar composition to bone. Turtles and crocodilians also possess dermal scales, but they arise via a different process.

Which of the following best describes the difference between reptiles and amphibians?

Amphibians do not have scales and their skin is permeable so allow the diffusion of gasses. Reptiles are covered with scales and have tough skin so that they can easily adapt to the terrestrial environment. Fish have scales.  Pisces have dermal scales while reptiles have horny epidermal scales. So, the correct answer is option C.

Do fish have scales or scales?

All fish have a slime coat secreted from under the scales. This slime coat keeps the fish moist. It also protects against infection and parasites. Some fish have a toxic slime layer, another defense against predators. Most fish do not shed their scales, unlike reptiles who shed their skin as they grow. Scales are more like human skin.

Which of the following correctly describes one difference between nematodes and arthropods?

Which of the following statements correctly describes one difference between nematodes and arthropods? nematodes have an open circulatory system and arthropods have a closed circulatory system arthropods have an open circulatory system while nematodes do not have a circulatory system

Do fish have scales and reptiles don t?

No, fish scales are dermal (= formed in derma) bones like skull roof bones. Scales in reptiles are formed by epidermis and are made primarily of protein (from keratinocytes), being similar in derivation to hair, feather and nails. Click to see full answer. Similarly one may ask, do fish and reptiles have scales?

What are scales made of in reptiles?

Do fish have scales on their skin?

No, fish scales are dermal (= formed in derma) bones like skull roof bones. Scales in reptiles are formed by epidermis and are made primarily of protein (from keratinocytes), being similar in derivation to hair, feather and nails. Click to see full answer. Keeping this in consideration, do fish and reptiles have scales?

Is a fish scale a bone?

No, fish scales are dermal (= formed in derma) bones like skull roof bones. Scales in reptiles are formed by epidermis and are made primarily of protein (from keratinocytes), being similar in derivation to hair, feather and nails. Click to see full answer.

Why do arthropods and velvet worms develop differently from each other?

– arthropods and velvet worms have a different set of homeotic genes, which causes them to develop differently – arthropods and velvet worms have the same set of homeotic genes and these are expressed similarly in both groups of animals

Why do arthropods have so many body segments?

increase in the number of homeotic genes led to the diversity of segment and appendage types in arthropods (proved false because velvet worms had same set of arthropod homeotic genes – conclusion: body segments did not arise from new homeotic genes ) second hypothesis of why the arthropod body plan is successful

What is the difference between nematodes and arthropods?

arthropods have an open circulatory system while nematodes do not have a circulatory system A land snail, a clam, and an octopus all share distinct cephalization.

What do all arthropods have in common?

list characteristics arthropods have in common. hard skeleton; specialized joint appendages; segmentation insects make up nearly 75% of all animal species; can fly, waterproof coating on cuticle and have complex life cycle; 3 pair of legs; insect life cycle

Why don’t amphibians have scales?

Amphibians don’t have scales because they would block oxygen and water absorption. Frogs, salamanders, and their relatives evolved to survive with permeable skin. Unlike terrestrial tortoises and turtles, all amphibians absolutely must have access to absorb water or moisture through their skin, or they would dehydrate and perish.

What are the scales of reptiles made of?

The scales of reptiles, unlike the separate glossy scales of fishes, are made of protein and are part of the skin itself. The scales are all connected to one another by hinges of skin.

Do cartilaginous fish have scales?

However, cartilaginous fish do not have scales. Fish scales originate from the skin and resemble the structure of their teeth. Reptile skin has horny epidermis which is watertight, thus making it possible for them to survive on land. Reptiles also have scales to protect exposed parts of their skin.

Do fish have scales on top of their skin?

Bony fish, such as whiting, carp, and perch, have overlapping wet scales. Each scale is attached to an inner layer of skin. On top of the scales is a slimy mucous liquid, which is why fish feel slippery. Glands (special holes in the skin) secrete (pump out) this mucous from underneath the scales.

Are sea daisies related to arthropods and velvet worms?

– arthropods and velvet worms have the same set of genes, but these are expressed at different body locations in each group of animals arthropods and velvet worms have the same set of genes, but these are expressed at different body locations in each group of animals Sea daisies are tiny marine animals found in deep water.

What is the difference between amphibians and reptiles Quizlet?

An amphibian is a jawed vertebrate with amniotic eggs. A reptile is a tetrapod. A hagfish is a vertebrate. Lampreys are jawed vertebrates. A reptile is a tetrapod. Tiktaalik is an example of a transitional form linking __________ to ancestral __________. Which of the following statements regarding amphibians is FALSE?

How did the evolution of arthropods occur?

The evolution of arthropods occurred following the loss of body segments, development of specialised legs and a more developed head. The chitinous exoskeleton acts as a form of armor for arthropods.

What caused the divergence between arthropods?

This divergence is believed to have occurred more than 500 million years ago during the Cambrian Explosion, a period on Earth when many of the current groups of animals first evolved. The evolution of arthropods occurred following the loss of body segments, development of specialised legs and a more developed head.

What is an arthropod?

Bob Strauss is a science writer and the author of several books, including “The Big Book of What, How and Why” and “A Field Guide to the Dinosaurs of North America.” Arthropods—invertebrate organisms equipped with exoskeletons, jointed legs, and segmented bodies—are by far the most common animals on earth.

Do all arthropods have segmented bodies?

All Arthropods Have Segmented Bodies. Millipede. Gerald Yuvallos / Flickr / CC by SA 2.0. A bit like modern houses, arthropods have modular body plans, consisting of the head, the thorax, and the abdomen (and even these segments are composed of varying numbers of other segments, depending on the invertebrate family).
