Study Notes
Yeast (Candida)
- Candida is a genus of yeasts and is the most common cause of fungal infections worldwide.
- Candida can cause infections (candidiasis or thrush) in humans and other animals when the host's immune system is compromised.
- Candida albicans is the most commonly isolated species.
Vertebrates
- Vertebrates include reptiles, birds, and mammals.
Reptiles
- Live on land and some in water.
- Breathe through lungs.
- Skin is covered in scales and some have a shell.
Birds
- Live on land and in air.
- Breathe through lungs.
- Have feathers and wings.
Mammals
- Live on land and some in water.
- Breathe through lungs.
- Body is covered in skin and fur.
- Babies feed on their mother's milk.
Invertebrates
- Are animals that do not have a spinal column or a skeleton made of bones.
- Found in a vast range of habitats, from forests and deserts, to caves and seabed mud.
- Nearly 2 million species of invertebrates have been identified.
- These 2 million species make up about 98% of the total animals identified in the entire animal kingdom.
Similarities between Vertebrates and Invertebrates
- The feature uniting all chordates (all vertebrates and some invertebrates) is that at some stage in their lives, all have a flexible supporting rod, a notochord that runs through the length of their bodies.
Learn about Candida yeast, a common cause of fungal infections, and get introduced to vertebrates, including reptiles, birds, and mammals.
