Minimum and Maximum Depths of Stony Coral Species in Caribbean and Indo-Pacific Waters

|---|---|---|---|
| Acropora awi | Indo-Pacific | 0 | 5 |

A marine biologist is researching four stony coral species in Caribbean and Indo-Pacific waters, focusing on sightings of these species in the shallow zone (less than 30 meters below the surface) and the mesophotic zone (30 meters or more below the surface). After comparing the recorded minimum and maximum depths of each species, the biologist concludes that the two species whose entire recorded depth ranges stay within 30 meters of the surface are those found in __________
