Biology Quiz: Amphibians and Fishes

Fishes are specifically structured to thrive in an aquatic environment.

Organs that allow fish to breathe underwater; they can't survive out of water.

Fish have a heart with only two chambers, for circulating blood.

Fishes do not regulate their body temperature internally; it's influenced by the environment.

Cartilaginous fishes have a cartilage skeleton (e.g. sharks), while bony fishes have a skeleton made of bones.

A type of animal that lives both in water and on land during different life stages.

The early life stage of amphibians, where they live in water and breathe through gills.

Amphibians have skin that is wet and helps them in respiration and hydration.

An amphibian heart that has three chambers: two atria and one ventricle.

Amphibians are ectothermic, meaning their body temperature varies with the environment.

Warm-blooded vertebrates with hair and milk glands for their young.

Specialized glands in mammals that produce milk to nourish their young.

Mammals give live birth and do not lay eggs, with few exceptions.

Mammals have hair, warm blood, lungs, a diaphragm, and a four-chambered heart.

Mammals like the platypus and spiny anteater that lay eggs instead of giving live birth.

Reptiles have rough skin and breathe through lungs since birth.

Crocodiles hunt in water but are adapted for life on land.

Reptile eggs are leathery and laid outside water on riverbanks.

Reptiles use lungs to breathe from the moment they are born.

Reptiles have external scales for protection and moisture retention.

Birds are warm-blooded, have feathers, and lungs for breathing.

Birds have a four-chambered heart with two atria and two ventricles.

Birds' forelimbs are modified into wings; their legs are slender and scaly.

Mammals like cats and dogs have hair or fur and typically give live birth.

Warm-blooded animals maintain a constant body temperature despite the environment.

Marine animals that belong to the echinoderm group, like starfish and sea urchins.

Body plan where parts are arranged around a central axis, allowing equal division.

A flexible rod-like structure that supports the body of vertebrate animals during development.

Animals that have a notochord and a backbone, categorized as chordates.

Small, flexible structures that allow echinoderms like starfish and sea cucumbers to move.

A phylum of soft-bodied animals with hard covers, like snails.

Characteristic of Mollusca, lacking segments and with a fleshy structure.

A distinct feature of Mollusca aiding in movement, such as walking.

A phylum of spiny-skinned animals including starfish and sea cucumbers.

Includes starfish, brittle stars, sea urchins, and sea cucumbers.

Cylindrical, elongated, unsegmented worms often found as parasites.

Segmented, cylindrical worms with a well-developed digestive system, including earthworms and leeches.

Unsegmented body filled with fluid, enabling movement and support.

Both have a bifid digestive system, meaning separate mouth and anus.

Includes earthworms and leeches that have segmented bodies with a developed digestive system.

A large group of organisms with segmented bodies, jointed limbs, and a chitin covering.

Limbs that are connected by joints, allowing flexibility and movement in various organisms.

A thick, outer layer found in many arthropods that is shed periodically during molting.

Earthworms have a long, cylindrical body with 80-100 rings.

The clitellum is a reproductive band located between segments 14-16.

Earthworms do not have jaws or teeth, they contribute to soil fertility.

Earthworms belong to the phylum Annelida.

Vermiculture involves using earthworms to increase soil fertility.
