ZOOLOGY MISCELLANEOUS (Part-II)

• These animals rely on sources like sunlight, warm surfaces, or water to maintain a suitable body temperature.

common cold-blooded animals:

1. Reptiles

   • Snakes

   • Lizards

   • Turtles and Tortoises

   • Crocodiles and Alligators

   • Geckos

2. Amphibians

   • Frogs

   • Toads

   • Salamanders

   • Newts

3. Fish

   • Salmon

   • Trout

   • Sharks

   • Goldfish

   • Tuna

4. Invertebrates

   • Insects (e.g., ants, butterflies)

   • Arachnids (e.g., spiders, scorpions)

   • Mollusks (e.g., snails, clams)

   • Crustaceans (e.g., crabs, lobsters)

• It's a physiological response to cold weather and lack of food, characterized by lower body temperature, slower breathing, and lower metabolic rate, allowing them to conserve energy.

e examples of animals that hibernate or enter dormancy:

1. Mammals:

   • Bears (deep sleep, not true hibernation)

   • Hedgehogs

   • Bats

   • Ground squirrels

   • Prairie dogs

2. Reptiles:

   • Snakes (e.g., garter snakes) undergo brumation (a form of dormancy).

3. Amphibians:

   • Frogs

   • Toads

4. Insects:

   • Ladybugs

   • Caterpillars

   • Bees

• They are invertebrates belonging to the class of Anthozoa.
• The name Cnidaria (with a silent ‘c’) refers to the cnidae, or nematocysts, that is, the cellular entity of the venom apparatus, which all Cnidarians possess.

The phylum Cnidaria includes

anemones,

1. corals,
2. jellyfish (including box jellyfish),
3. and hydras.

• The term “Photoperiodism” was coined to describe a plant's ability to flower in response to changes in the photoperiod: the relative lengths of day and night.
• Because flowers produce seeds, flowering is crucially important for the plant to complete its life cycle.

• This acid is responsible for the burning and stinging sensation associated with these bites.

• It has been used as a mild general anesthetic, especially in dentistry, due to its analgesic (pain-relieving) and sedative effects.

• It is the best source of energy for beings (human beings).
• It is not an excreted (residual) substance, whereas all other three substitutes are excreted substances.

• When iodine comes into contact with starch, it forms a dark blue-black complex.
• This is a common chemical test for starch.

• They are quickly broken down into glucose, which is then used by cells for fuel, making them ideal for providing instant energy during physical activity.
