Joker Coral
Euphyllia glabrescens
Joker coral inhabits sheltered tropical reefs in the Indo-Pacific, anchoring its hard skeleton among rock and reef rubble. Its fleshy tentacles extend mainly at night to catch zooplankton and small suspended food particles, while symbiotic algae provide much of its energy in daylight. Long, stinging sweeper tentacles can be used to defend space from neighboring corals. Its brightly colored tentacle tips are often fluorescent under blue reef light.
