PORIFERA

Sponges are animals of the phylum Porifera . Their bodies consist of jelly-like mesohyl sandwiched between two thin layers of cells.

MAMMALS

Mammals are a class of vertebrate animals whose females are characterized by the possession of mammary glands while both males and females are characterized by sweatglands, hair, three middleairbones used in hearing, and a neocortex region in the brain. Mammals are divided into three main infraclass taxas depending how they are born. These taxas are: monotremes, marsupials and placentals.

BIRDS

Birds are winged, bipedal, endothermic, 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. .

ARTHROPODS

Arthropods are animals with segmented bodies and six or more jointed legs. They are the largest animal group on Earth.Arthropods are generally small. Most are less than 1 cm long. Most belong to one of three major groups: insects, crustaceans, or arachnids.

Coconut crab:
The coconut crab is the world’s largest terrestial arthropod in the world and is known for its ability to crack coconuts with its pincers. They can weigh up to 4kg (Some reports claim up to 17kg) and leg span of 1m.

MOLLUSCS

The molluscs rival the arthropods in their diversity of body forms and sizes, as well as their ecological success. The phylum also provides some of the most familiar animals, such as snails , clams, mussels, squids , and octopus .

GIANT SQUID:

The giant squid remains largely a mystery to scientists despite being the biggest invertebrate on Earth. The largest of these elusive giants ever found measured 59 feet (18 meters) in length and weighed nearly a ton (900 kg).
