Genus/Species    Naso vlamingii

GENERAL CHARACTERISTICS

Length to 60 cm (23 in). Adults develop a convexly rounded prominent snout and extremely tall dorsal and anal fins. Gray ovate compressed body with bright blue markings. Tips of the tail fin are unusually long. Courting males are able to instantaneously turn iridescent blue.

DISTRIBUTIN/HABITAT


Indo-Pacific in deep lagoon and seaward reefs from 4–50 m (12-150 ft). Diurnally in conspecific groups midwater off steep slopes.

DIET IN THE WILD


Zooplankton.

REPRODUCTION


External fertilization. Egg scatterers, non-guarding. Remarks: Courting males are able to instantaneously turn iridescent blue.

TAXONOMY

KINGDOM Animalia

PHYLUM Cnidaria (possess cnidocytes)

CLASS Anthozoa (Sea Anemones and Corals)

SUBCLASS Hexacorallia (water-based organisms formed of colonial polyps generally with 6-fold symmetry)

ORDER Scleractinia (Stony Corals)

FAMILY Merulinidae

GENUS Hydnophora sp.

GENERAL CHARACTERISTICS
Hexacoral or stonycorals with colonies that may be massive, encrusting, or branched; usually brown, greenish, or yellowish. Conical protuberances over the entire colony’s surface. Tentacles often partially extended during the day.

DISTRIBUTION/HABITAT
Widely distributed in the Indo- Pacific. Common in variety of reef habitats.

DIET IN THE WILD
Nutrition mostly provided by symbiotic zooxanthellae, but also take other food sources, such as plankton.

REPRODUCTION: The small polyp stony (SPS) corals are male and female and can reproduce both sexually and asexually. They reproduce sexually by releasing eggs and sperm at the same time (spawning), resulting in a fertilized egg which then forms into a free-swimming planula larva. Eventually the planula larvae settles onto the substrate, becoming plankters. This then forms a tiny polyp which begins to excrete calcium carbonate and develops into a coral. Planula larvae are extremely vulnerable to predation, and very few survive. Hydnophoras reproduce asexually from breakage due to storms resulting in fragmentation.

REMARKS: Hydnophora are very aggressive and can extend sweeper polyps and sting or basically eat other corals it touches.

Phylum Cnidaria, Class Anthozoa, Order Scleractinia, Family Acroporidae,

Acropora spp.

DISTRIBUTION:  Indo-Pacific, Caribbean.

HABITAT: Habitat: Shallow reef environments with bright light and relatively strong currents. Often dominate shallow parts of the reef, especially the surf zone

APPEARANCE: Growth forms extremely variable: slender branched fingers, broad antlers, table-like plates are common. Among the most colorful of reef-building corals; may be cream, yellow, blue, green, purple, pink, even fluorescent. Polyps small; set along the branches.  Characterized by light-colored polyps at the tips of branches where budding and growth take place, fueled by the energy produced by zooxanthellae in lower parts of the branch that give it color

DIET: Feed on microplankton, mostly at night; significant nutrition provided by photosynthetic zooxanthellae

REPRODUCTION/DEVELOPMENT: These fragile corals usually reproduce without sex (asexually). As pieces break off, they grow on their own as clones (fragmentation). But spring and summer bring an orgy of sex. Warming waters and a full moon can stimulate hundreds of corals to release clouds of eggs and sperm into the water at the same time. Most Acropora species are broadcasters, a few are brooders.

REMARKS: A major contributor to reef structures worldwide.
