Sabse Bada Variety-Bhara Kingdom 🐾
Animalia mein sabse zyada variety hai - chhoti si sponge se lekar blue whale tak! Saare animals eukaryotic, multicellular, heterotroph (khaana doosron se) hote hain, aur inke cells mein cell wall NAHI hoti. Inhe body design ke hisaab se groups (phyla) mein baanta gaya hai.
📌 Do bade group: Invertebrates (jinme reedh ki haddi / backbone NAHI hoti) aur Vertebrates (jinme backbone hoti hai). Chaliye simple se complex tak dekhte hain.
🐚 Invertebrates (Bina Backbone Wale)
| Phylum | Khaas baat | Example |
|---|---|---|
| Porifera | Sponges - body mein pores (chhed), simplest animals | Sycon, Spongilla |
| Coelenterata | Hollow body + tentacles, paani mein | Hydra, Jellyfish, Coral |
| Platyhelminthes | Flatworms - chapte body | Planaria, Tapeworm (parasite) |
| Nematoda | Roundworms - gol, lambe | Ascaris, Filaria worm |
| Annelida | Segmented (tukdon wale) body | Earthworm (kenchua), Leech (jonk) |
| Arthropoda | Jointed legs, sabse bada phylum | Insects, Spider, Crab, Prawn |
| Mollusca | Soft body, aksar shell | Snail (ghongha), Octopus, Mussel |
| Echinodermata | Spiny (kaantedaar) skin, samundari | Starfish, Sea urchin |
Duniya ke 80% se zyada animals Arthropoda phylum ke hain! Har cheenti, makkhi, machhar, titli, makdi, jhinga - sab isi mein. Agar aap kabhi keeda dekho, toh 8 mein se 7 baar wo arthropod hi hoga.
🦴 Chordata (Backbone Wale - Vertebrates)
Chordata phylum ke advanced members mein reedh ki haddi (backbone/vertebral column) hoti hai - inhe Vertebrates kehte hain. Inke 5 classes hain:
| Class | Khaas baat | Example |
|---|---|---|
| Pisces (Fish) | Paani mein, gills se saans, scales, fins | Rohu, Shark |
| Amphibia | Paani + zameen dono par, chikni skin | Frog (mendhak), Toad |
| Reptilia | Rengne wale, sookhi scaly skin, ande | Snake, Lizard, Turtle |
| Aves (Birds) | Par (feathers), chonch, ande, ud sakte | Crow, Pigeon, Peacock |
| Mammalia | Baal, bachche ko doodh (mammary glands), warm-blooded | Insaan, Dog, Whale, Bat |
Whale paani mein rehti hai par ye mammal hai, machhli nahi - kyunki wo apne bachchon ko doodh pilaati hai aur phephdon (lungs) se saans leti hai (isliye baar-baar paani ke upar aati hai). Isi tarah chamgadad (bat) ud-ti hai par bird nahi, mammal hai!
