From the oceans, let's rocket to the sky to understand about the powerful eagle, king predator of the sky. As the video does not mentioned anything much, below is a summary of the adaptations of the eagle. Eagle's Adaptations Eagles and other birds are commonly tested in Primary Science Examinations, especially with regards to their body shape, feet and beaks Primary 6 Science Application Questions: Adaptation QUESTION 1 Two birds, Bird A and Bird B, were kept separately in two cages as shown below. 300g of seeds and 50 ml of nectar were placed in each cage at the start of the experiment. After two days, the amount of seeds and nectar were recorded in the table shown below. Mass of seeds at the start of the experiment (g) Mass of seeds at the end of the experiment (g) Cage with Bird A 300 300 Cage with Bird B 300 100            Volume of nectar at the start of the experiment(ml) Volume of the nectar at the end of the experiment(ml) Cage with

From the land, let's move on to the pitch dark sea. In the dark, many water creatures seek out for the light. However, unbeknown to them, they are courting their own death. Let's take a closer look at this deep sea angler fish. You may find it familiar as you may have seen from the movie, Finding Nemo. Anglerfish Adaptations: Light-emitting structure - Structural adaptation to attract prey so as to catch it Waving light-emitting structure - Behavioural adaptation to attract prey so as to catch it Many sharp jagged-teeth that are angled inwards - Structural adaptation to catch hold of prey easily and preventing them from escaping   ¹   Extended jawline - Structural adaptation to swallow prey easily Expandable Stomach - Structural adaptation to feed on prey bigger than itself and stock up food in the food-scare dark waters  ¹ Special sense organ  - Structural adaptation to look for mate and reproduce Male anglerfish attach himself to female anglerfish: Behavi

The world's is full of surprising living creatures that have their own strategies to survive and adapt in the wild. By having various adaptations, be it structural or behavioural, the animals have enabled the survival and continuity of its own species. For the very first post of this series, we have the Regal Horned Lizard.  As you watch the video, take note of its adaptations and identify if it is structural or behavioural. Adaptations of Regal Horned Lizard Sticky tongue - Structural adaptation to catch its prey Immune to ants' venom - Structural adaptation to protect itself against prey Body of hard scales - Structural adaptation to protect itself against  prey Thin blood capillaries underneath  the lizard eyes that can rupture easily at will - Structural adaptation to escape from predator Squirt blood at predator: Behavioural adaptation to escape from predator Blood with anti-canine repellent property - Structural adaptation to escape from preda
