Horse behaviour Flashcards
What is the name of the 1st horse called?
The Dawn horse or the Hyracotherium
Give another name for the Hyracotherium
Eophippus
What size were Eohippus’s?
Approx the size of the Fox
(20 - 35 kg)
Where did the Eohippius live + what was their diet?
- Environment = Forests
- Diet = herbivorous (leaves + succulents)
True or False.
The Eohippus had larger premolars, than it’s molars.
False, the molars were larger than the premolars
True or False.
The Eohippus had pads on its toes, instead of hooves.
True!
What length were the Eohippus’s legs + how many digits did they have on their front + hind-legs?
- Length of the legs = short
- Foreleg digits = 4
- Hindleg digits = 3
Evoluntionary, what 5 physiological traits formed in horses?
- Increased body size
- Brain developed + specialised
- Their functioning toes decreased in numbers
- Hooves developed, to replace the toe pads
- Their limbs lengthed + the lower limbs fused
What are the main aims of the survival techniques that horses exhibit?
To avoid predation, based on detecting predators early in order to escape them
Are horses prey or predatory species?
Prey
What is the horses main form of escaping predation - fight, flight or freeze?
Flight
What phrase is used to define the type of prey species that horses are?
A Flight response animal
Why is flight the best predatory response for horses?
Because they are large animals, often found grazing in open environments.
+
Therefore, hiding is very unsuccessful - requiring flight response to survive
What 2 things do horses have to effecitvely perform, in order to avoid predation, during flight?
- React immediately
- Depart quickly
Name the main 4 anatomical + physiological adaptations that has aided the horse with its successful ability to flee predators
- Large space for lung expansion
- Large space for heart contraction
- Horses legs have adapted to reduce to single-toes for greater balance
- Concentrated muscle mass at the top of the limbs, for the horse to cover ground at high speed + quickly
True or False.
Being highly observant + highly reactive is not apart of the evolved predatory response, but due hormonal activity.
Obviously false, as it is a well adapted behavioural response to flee from danger
Just had couldn’t think of anything quick enough to compare lol sorry
Why do horses run first + think later?
Because they are highly evolved to escape predation, with their well-developed senses, always alert + anticipating danger in their surroundings, so their 1st response is to run 1st, think later!
True or False.
Horses live in herds, in the wild.
True, they are safer in numbers
What are the 3 reasons that horses are sensitive to their surroundings?
- Fear of the unkown, due to prey species + not having control of the situation
- Fear of pain, due to prey species + pain is associated with vulnerability to predators
- Constantly looking out for predators, to remain safe
Why is dominance important to maintain with the herd?
To establish roles + maintain them within the herd, with a hierarchy
What behaviour establishes herd hierarchy?
Aggressoin
What method of communication is used within the herd?
Body language
What is the type of group that is used to describe the herd that horses live in?
Harem
