- ecological features
- cilia, provides coral nutrition
- the physical structure of the reef also provides many places for animals to live
- the seawater must have low turbidity-turbid water reduces light penetration so photosynthesis would be reduced
- temp must remain constant between 25 to 29 degrees
- importance of tropical reefs
- provide valuable resources and help to resist damaging environmental changes
- support many species that are exploited for food
- provides medicines-species of sea squirt treat the cancer soft tissue sarcoma
- threats
- physical damage-litter can damage reefs
- pollution-large oil spills can cover coral reefs
- sedimentation-turbid water carried by rivers or sediments disturbed by coastal developments can cover and kill corals
- Conservation efforts
- Control of fishing-imposing a maximum catchable size to protect large individuals that are likely to produce many young
- control of tourism-activities may be restricted eg spear fishing may be banned
- reef creation-artificial reefs have been create from concrete structures
- ecological features
