(Echinothrix calamaris)
They use these spines to explore their environment, and the secondary spines as defense to protect their body or test.
(Pseudanthias bicolor) These fish occur at depths usually deeper than 30 feet, around corals and deep ledges. They typically like to be in strong currents that bring lots of plankton for them to feed on.
(Holothuria atra) This common Hawaiian cucumber is often found fully exposed on the ocean floor coated in sand. A small, spotted, commensal crab can be found living near its mouth.
(Chromis vanderbilti) These fish form large schools that feed on zooplankton above the reef and will quickly retreat into coral colonies if threatened by a predator.
(Dardanus sanguinocarpus) These hermit crabs get their commonname from the reddish-purple patch of exoskeleton above their pincers.
(Stylophora subseriata}
Corals are covered with polyps. Each polyp has a mouth surrounded by tentacles, just like anemones have.
(Acanthurus triostegus)
This fish gets its name
from its distinctive black stripes, which resemble an old-fashioned prison uniform.
