When coral reefs are damaged, they sometimes struggle to grow back because there aren't enough coral seedlings around, and the ones that are around are growing together too closely. Enter: the coral...
Within the Department of Invertebrate Zoology, scientists conduct original research on all 30 major invertebrate animal groups (phyla) of the world (except insects), and are stewards for the 35...
The small larvae of elkhorn coral ( Acropora palmata ) settle and grow on the crustose coralline algae species Hydrolithon boergesenii .
I still haven’t gotten beyond the ‘gee whiz’ factor of studying communities of animals in deep-sea coral habitats. Climbing over undersea mountains and along the steep cliffs of submarine canyons...
Dead man’s fingers ( Alcyonium digitatum ) are soft corals named for their appendage-like appearance when thrown ashore by storms. The finger-like clumps of coral polyps come in various shades of...
