Bringing the Ocean Home.

Of all Philip Henry Gosse’s works, the most successful was The Aquarium, in which he described his observations of coastal life and — a year after establishing the first public aquarium at the London Zoo — gave his readers instructions on how to build a miniature ocean of their very own.
A saltwater aquarium, he asserted, was the perfect way to get acquainted with the peculiar creatures of the ocean without having to descend into the depths using complicated diving equipment.
He was amused by a French zoologist, Henri Milne-Edwards, who stalked around at the bottom of the Mediterranean wearing a “water-tight dress, suitable spectacles, and a breathing tube” in order to take a closer look at the submarine world.
All this was so much easier to achieve, Gosse proclaimed, in the safe environment of one’s own four walls. In his many long-winded reports about his coastal excursions, Gosse told his readers that the aquarium was the objective, but that many obstacles still had to be overcome.
One’s relation with nature required a cautious and respectful approach, for its exploration was, in Gosse’s mind, a spiritual exercise.
For Gosse, religion and natural science went hand in hand: “it brings us, in some sense, into the presence of God”, he said, “or rather it gives us cognizance of Him, and reveals to us some of his essential attributes”.

The Green Goliath Grouper.

The German ichthyologist M.H.C. Lichtenstein described the goliath grouper as Serranus itajara in an 1822 publication regarding the natural history of Brazil.
In an 1884 work, “The fishes of the Florida Keys,” David Starr Jordan proposed the inclusion of the goliath grouper in Epinephelus (Bloch 1793) and this combination remains in use today. Of incidental note is the fact that various authors have incorrectly spelled the specific epithet “itajara” as “itaiara.”
The genus name comes from the Greek epinephelos translated as cloudy. Synonyms of E. itajara include Serranus guasa Poey 1860 and Serranus quinquefasciatus Bocourt 1868.
A number of authors treat the name Promicrops itajara as valid taxonomy for the goliath grouper.
The goliath grouper occurs in the western Atlantic Ocean from Florida south to Brazil, including the Gulf of Mexico and the Caribbean Sea.
It is also found in the eastern Atlantic Ocean, from Senegal to Congo although rare in the Canary Islands.
The species is also present in the eastern Pacific Ocean from the Gulf of California to Peru.

Last South African coelacanths threatened by oil exploration.

Coelacanths have remained almost unchanged for 420m years.

Older than dinosaurs and weighing as much as an average-sized man, coelacanths are the most endangered fish in South Africa and among the rarest in the world.
Barely 30 of these critically-endangered fish are known to exist off the east coast of South Africa, raising concern that a new oil exploration venture in the area could jeopardise their future.
Coelacanths, whose shape has remained almost unchanged for 420m years, captured world attention when the first living specimen was caught off the port city of East London in 1938.
This discovery was followed by the subsequent capture of several more off the Comoros islands in the early 1950s, confirming that coelacanths were definitely not extinct.Shelf Life:
”The Sodwana coelacanths are about 40km from the northern boundary of the Eni exploration area and nearly 200km north of the first drilling sites, but Venter said oil spills spread far and swiftly.His concerns have been echoed by the coelacanth expert Prof Mike Bruton, who said the fish are specialist creatures, sensitive to environmental disturbance.

“Anything that interferes with their ability to absorb oxygen, such as oil pollution, would threaten their survival. The risk of oil spills or blowouts during exploration or futur is a source of serious concern.”

Siamese Fighting Fish, Thailand.

Bangkok-based photographer Visarute Angkatavanich (previously) continues to capture some of the most elegant portraits of fish we’ve seen.
His intimate, crystal-clear photos of Siamese fighting fish (betta) make it seem as though they are suspended in air instead of water.
Angkatavanich recently told Popular Photography that he only started photographing the fish after encountering them for the first time three years ago at a fish show and has since become obsessed with the different species which vary greatly in size, shape, and color patterns.

The Fins of the Ribbonfish.

Up to 2m long the ribbonfish is an elegant deep-sea creature.
Named for the elaborate fins that ripple delicately after them as they swim, ribbonfish from the genus Trachipterus are found all over the world.
There are six known species, and Australia’s is the southern ribbonfish, a 2m-long silvery creature with black polka dots on its sides and bright red fins.
Found off the coast of southern Queensland and South Australia, the southern ribbonfish has also set up a population off the coast of South Africa.
This fish is pretty much a taxonomic nightmare, because while it’s certainly a single species, according to the Australian Museum no one can decide whether its correct scientific name is T. jacksonensis or T. arawatae.

The spectacular Achilles Tang.

In other places around the world, coral has been decimated by bleaching and disease, but the southern Line Islands’ reefs retain their resilience.
Scientists believe the key to coral health is intact ecosystems, where all the native species—including planktivores such as the vividly marked Achilles tang seen here—play their part.
The Achilles tang is one of the most spectacular fish available for the aquarium, but it is also one of the most difficult to keep.
This fish swims continuously, and usually at a very high speed, so it requires a large tank with plenty of open space.
It also requires fairly turbulent water movement.
When kept in conditions of less-than-ideal water movement and/or in too small a tank, this fish will be very nervous, usually not feed, and wither and die fairly quickly.
It is usually fairly expensive, so this may help prevent hobbyists with less-than-ideal conditions from keeping this fish.
