3-24-14 Sixbar Wrasse From Ron’s Tropical Marine Series

Filed under: CORAL REEF, TROPICAL MARINE — Leave a comment
March 24, 2014

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Labridae (Wrasses)

Genus/species: Thalassoma hardwicke

Sixbar Wrasse8410603333_678203e399_b

GENERAL CHARACTERISTICS: Adult is pastel blue to pale green with six dark, vertical bars on their body, the last two saddling the tail. The head has a distinct ‘daisy’ print around the eyes made of a few different pastel colors (e.g., pink bands radiating from the eye) in larger adults.  Max length: 20 cm (7.9 in).

DISTRIBUTION/HABITAT: Found in the tropical Indo-Pacific in shallow lagoons and seaward reefs. Depth to 15 m (50 ft.).

DIET IN THE WILD: Carnivore on benthic and planktonic crustaceans, invertebrates and small fishes.

Sixbar Wrasse8393609669_e1f3601c7c_b

REPRODUCTION: Protogynous hermaphrodite; Hermaphroditism occurs when a given individual in a species possesses both male and female reproductive organs, or can alternate between possessing first one, and then the other. The most common pattern is for a female to change into a male (protogyny). This often happens when a large dominant male is removed by a predator. Within a few days, the largest female in the harem becomes a dominant male and takes over the missing male’s function. This pattern is common in coral reef fishes, such as parrotfishes, wrasses, and groupers.
T.hardwicke is a pelagic spawner meaning water currents widely disperse the young. The eggs, embryos and larvae of pelagic spawners contain oil globules or have a high water content. As a result, they are buoyant and are widely dispersed by currents. The downside is that mortality is high, because they can be eaten so easily by pelagic predators. Pelagic spawners who live in or around coral reefs can spawn a small number of eggs almost daily over a period of months.

CONSERVATION: IUCN; least concern

REMARKS. Occur in small, loose groups.

TAXONOMY
Kingdom:Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes) 
Family: Labridae (Wrasses)

Genus/species: Cirrhilabrus solorensis

Cirrhilabrus solorensis3380013623_6c8c3e586c_b

GENERAL CHARACTERISTICS: Highly variable. The eye is bright red. Males usually have a dark band along the end of the gill covering. Change color and sex with growth. Females are able to change sex into an often brilliantly colored terminal male phase. Max. size: 11 cm (4.3 inches).

DISTRIBUTION/HABITAT: Found in the Western Central Pacific and Indonesia. in coastal to outer reef lagoons on rubble and coral habitats.

DIET IN THE WILD: Zooplankton.

Cirrhilabrus solorensis3813060378_a4f75890b9_b

REMARKS: The cornea of the eye of fairy wrasses is divided into two segments, essentially forming a double pupil. It is thought that the center pupil is a close-up lens that lets the fish have a magnified view of their small prey.

3-6-14 Reef Butterflyfish from Ron’s tropical Marine Series*

Filed under: TEMPERATE MARINE, TROPICAL MARINE — Leave a comment
March 6, 2014

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch likes)
Family: Chaetodontidae (Butterflyfishes) The name “Chaetodontidae” means “bristle-tooth”.

Genus/species: Chaetodon sedentarius.

Reef butterflyfish Chaetodon sedentarius ChaetodontidaeIMG_5652

GENERAL CHARACTERISTICS: Silver body, yellow and black dorsal fin, and yellow tail; two vertical black bars, one on the head through the eye and a black bar across the caudal peduncle. Max length: 6 inches (15 cm). 

DISTRIBUTION/HABITAT: a tropical western Atlantic species, found in the waters of the Carolinas to northern South America, including the Gulf of Mexico and the Caribbean Lives in the shallows and as deep as the light restricts coral growth. ( 48-130 feet deep).

DIET IN THE WILD: Coral polyps, polychaete worms, shrimps, amphipods and hydroids. Can be quite acrobatic in its feeding, often swimming upside down to get into crevices where prey might be hiding.

REPRODUCTION: Found in pairs, suggesting monogamy. The larvae of butterflyfishes are unique from all other species of fish. The head is encased in bony armor and large bony plates extend backwards from the head. These larvae, called “tholichthys,” grow to about 20mm, after which they settle on the bottom during the night.

PREDATORS: Preyed upon by larger fish, such as moray eels, snappers, and groupers. If it can’t find cover, will defend itself by facing its predator with dorsal spines erected, suggesting a sharply distasteful meal.

CONSERVATION: IUCN:  Least concern (LC)

REMARKS: Gets its name from its flitting movements about the reef and its beautiful color pattern that resembles the movements and appearance of the insect. 

Caribbean reef,  Currently not on exhibit

2-24-14 Regal Angelfish from Ron’s Tropical Marine Series

Filed under: ANGELFISHES, CORAL REEF, TROPICAL MARINE — Leave a comment
February 24, 2014

TAXONOMY
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch-likes)
Family: Pomacanthidae (Angelfishes)

Genus/species: Pygoplites diacanthus

GENERAL CHARACTERISTICS: Identified by 7 or 8 dark edged bluish-white bars that run horizontally down its body. Its body is yellow with blue coloration on the rear of the dorsal fin and it has a small dark patch over its eye. It has a strong preopercular spine. The anal fin has yellow and blue stripes. Juveniles are similarly colored to adults except for a large false eye-spot at the base of the dorsal fin. This fades as the fish matures and it’s gone by the time the fish reaches a length of 6-7 cm. The maximum adult size is reported to be between 20 and 30 cm (8 and 12 inches).

Regal Angelfish Pygoplites diacanthus

DISTRIBUTION/HABITAT: P. diacanthus is found throughout the Northern and Western Indian Ocean, the Red Sea, and the Indo- Pacific Ocean. They are commonly observed as solitary individuals and in pairs and never stray far from a reef crevice. The maximum adult size is reported to be between 20 and 30 cm (8 and 12 inches).
They are always on the move swimming from crevice to crevice in search of food. Found at depths from 1-20 meters (3-66 ft.)

DIET IN THE WILD: Sponges and tunicates.

CONSERVATION: IUCN Least concerned.

Location: Water planet coral exhibit WP33

2-21-14 Raccoon Butterflyfish from Ron’s Tropical Marine Series

Filed under: TROPICAL MARINE — Leave a comment
February 21, 2014

TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii (ray-finned fishes)
Order: Perciformes (Perch likes)
Family: Chaetodontidae (Butterflyfishes)

Genus/species: Chaetodon lunula

3120146362_b277962165_o

GENERAL CHARACTERISTICS: Yellow-orange with darker upper half of the body. It has a black patch around its eyes (similar to a Raccoon masked face) with a broad white stripe posterior to it. Two black stripes bordered in yellow reach from the white stripe to the dorsal fin. Black markings around its eyes suggestive of a Racoon. Maximum length to 8 inches.

DISTRIBUTION/HABITAT: From East Africa throughout the Indo-Pacific, south to Australia, east to Hawaii. Found in shallow reef flats of lagoon and seaward reefs, to depth of 30 m (98 ft).

DIET IN THE WILD: Nocturnal omnivore feeding on coral polyps, worms, crustaceans, plankton, algae

REPRODUCTION: Oviparous forming pairs during breeding.

CONSERVATION: IUCN Least Concern (LC)

REMARKS: Chaetodon means “bristletooth,” and has a dental array well-suited to its diet. Has a great fondness for coral polyps, which makes our Steinhart denizen a better fit for the Reef Lagoon which contains no corals. There it feeds on other invertebrates.
