Adaptations of Sea Creatures

1. Typical adaptations of animals living in deep caves are: lack of pigmentation, reduction in the size of eyes, and development of sensory mechanisms that do not depend on light for detecting food or predators.

2. Oxygen is not plentiful in these caves because there is no photosynthesis and very limited water circulation in the caves. The adaptations may be behavioral, morphological, physiological, -swimming slowly. Increased size of sensory body parts and reduce energy used up by unused body parts. Low metabolic rates and accumulation of lipids which contain about twice as much energy per gram as proteins or carbohydrates.

3. Adaptations are random and if they provide an advantage, the organism is more likely to survive and reproduce than other organisms with these same adaptations.
