Invertebarte 1: Jelly fish • Jellyfish go through several stages during their lifecycle and the form that you usually associate with jellyfish, medusas, is only one of them. There is for instance a phase called planula, where the jellyfish is in a type of larval stage. The planulae eventually attach themselves to surfaces where they become polyps which later turn into to medusas.

Invertebrate 2: Octopus • All octopuses have head, called mantle, surrounded with 8 arms, called tentacles. All vital organs are located in their head. Their color and size is determined by their environment. Those that live in colder water will be much larger than those that live in tropical (warm) water. They reproduce sexually.

Vertebrate 1: Lion • Lions consume a wide variety of prey, from wildebeest, impala, zebra, giraffe, buffalo and wild hogs to sometimes rhinos and hippos. The males hunt while the female watches the cubs. They reproduce sexually and are mammals. They are the second biggest species of cats after tigers

Vertebrate 2: Panda • Giant pandas are found mostly in thick bamboo and coniferous forests at 8, 500 to 11, 500 feet in elevation. They are generally solitary animals that spend most of their days feeding. However, they do communicate with each other once in a while through scent markings, calls and occasional meetings. Cubs are born blind and helpless and if there are twins, only one cub survives. The cub's eyes open at six to eight weeks and it starts to move around at three months. Also reproduce sexually. It is a bear

Vertebrate 3: koalas • They are MARSUPIALS, which means that their young are born immature & they develop further in the safety of a pouch. hen the baby is born, it's only about 2 centimeters long, is blind and furless and its ears are not yet developed. On its amazing journey to the pouch, it relies on its well-developed senses of smell and touch, its strong forelimbs and claws, and an inborn sense of direction. In the pouch, it attaches itself to one of the two teats which swells in its mouth, preventing it from being dislodged from its source of food. They also reproduce sexually and are not bears.
