Responding to changes in internal and external environment
A Dolphin must be able to respond to changes in its internal and external environment such as changes in light, water temperature, climate change and pollution.
When there's changes in light dolphins can adjust to this because of their pupils. They recognise some colours and their pupils adjust to light and dark. When the environment gets too dark they have a well developed sense of hearing to help them navigate their environment.
Dolphins usually live in cooler climates and use their blubber to keep them warm. If the water is too warm they just move to another area with cooler temperatures.
Climate change is a big threat towards the life's of dolphins. Melting of ice is causing both sea temperatures and water levels to rise. This affects the numbers and types of prey available to dolphins and effects their swimming pattern. Eventually the ability for dolphins to breed successfully may be affected due to these changes.
Marine rubbish can sometimes be the cause of death or injury. It may pollute the water, concentrate in the dolphin's blubber and be transferred to its young through the mother's milk. Solid litter can be swallowed, can cause the dolphin to choke on it or may entangle a dolphin causing it to drown and die.
