Ang Alibata

Ang Baybayin o Alibata (alam sa Unikodigo bilang Tagalog script o panitik na Tagalog) ay isang katutubong paraan ng pagsulat ng mga Pilipino (mga salitang katutubo sa kapuluan ng Pilipinas) bago pa dumating ang mga mananakop na Kastila. Ito ay hango sa Kavi na paraan ng pagsulat ng mga taga-Java at iba pang bahagi ng Timog Silangang Asya. Ito ay bahagi ng sistema o pamamaraang Brahmic (na nagsimula sa eskrito o sagisag na Sanskrit) at pinaniniwalaang ginagamit noong ika-14 siglo. Ito ay patuloy na ginagamit nang dumating ang mga Kastila hanggang sa huling bahagi ng ika-19 siglo. Ang ibang kahalintulad na mga paraan ng pagsulat ay ang mga Hanunóo, Buhid, at Tagbanwa. Ang salitang baybayin sa kasalukuyang wikang Tagalog ay katunayang nangangahulugan ng pagbigkas/pagsulat ng mga titik ng isang salita, o "to spell" sa wikang Ingles.

The Classification of Animals

The Animals with Backbones

Amphibians

Amphibians (class Amphibia), such as frogs, toads, salamanders, newts, and caecilians, are ectothermic (or cold-blooded) animals that metamorphose from a juvenile water-breathing form, to an adult air-breathing form. Though amphibians typically have four limbs, the Caecilians are notable for being limbless. Unlike other land animals (amniotes), amphibians lay eggs in water. Amphibians are superficially similar to reptiles.

California Newt

Wood Frog

Tree Frog

Marbled Salamander

Leopard Frog


Mammals

Mammals (formally Mammalia) are a class of vertebrate animals whose females are characterized by the possession of mammary glands while both males and females are characterized by sweat glands, hair, three middle ear bones used in hearing, and a neocortex region in the brain.

Elephant
Leopard
Fox
Panda
Lynx
Lion
Zebra
Wild Cat
Tiger


Reptiles

Reptiles, or members of the class Reptilia, are air-breathing, cold-blooded amniotes that have skin covered in scales or scutes as opposed to hair or feathers. They are tetrapods (having or having descended from vertebrates with four limbs) and lay amniote eggs, whose embryos are surrounded by the amnion membrane.
Chameleon
Sand Skink
Nile Crocodile
Green Turtle

Green Iguana
Water Snake
Spectacles Cobra

Birds

Birds (class Aves) are winged, bipedal, endothermic (warm-blooded), vertebrate animals that lay eggs. There are around 10,000 living species, making them the most numerous tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic to the Antarctic. Birds range in size from the 5 cm (2 in) Bee Hummingbird to the 2.7 m (8 ft 10 in) Ostrich.

Fish

A fish is any aquatic vertebrate animal that is typically ectothermic (or cold-blooded), covered with scales, and equipped with two sets of paired fins and several unpaired fins. Fish are abundant in the sea and in fresh water, with species being known from mountain streams (e.g., char and gudgeon) as well as in the deepest depths of the ocean (e.g., gulpers and anglerfish).
