Blowhole A hole found on the top of the heads of some aquatic animals that they breathe through

Breathing tube A tube used by some aquatic animals to take in air

Camouflage An organism’s ability to blend its body colour, shape or texture to match its surroundings

Climbers Plants that climb onto supports using their clasping roots

Creepers Plants that have long and thin stems which grow on the surface of the ground

Hibernate To enter an inactive state in which most body functions are slowed down to conserve energy so as to survive a period of time when food is scarce, especially during winter

Migrate To move from one location to another periodically or seasonally

Streamlined A body shape which many aquatic animals and birds have that allows them to overcome water resistance or air resistance respectively so that they can move with greater speed and ease

Structural A physical feature of an organism which helps it to survive in itsadaptation habitat

Tendrils Modifiedleaveswhichcertainplantshavethathelpthemhookonto a support so that they can climb vertically to get more sunlight
