What are iridescent sharks (Pangasianodon)?

Despite their shark-like appearance and massive size, Iridescent Sharks ( Pangasianodon hypophthalmus) are actually a species of scaleless freshwater catfish in the Pangasiidae family. So why are these timid and somewhat skittish fish only recommended for advanced or experienced aquarists?

Where do Iridescent sharks live?

Jump to navigation Jump to search. The iridescent shark (Pangasianodon hypophthalmus) is a species of shark catfish (family Pangasiidae) native to the rivers of Southeast Asia.

Do albino sharks have photophores?

While the albino shark Finucci described still had photophores, she speculates that the lack of pigmentation may have made it difficult for other individuals to recognize the female as one of their own, therefore impacting its ability to mate.

Are there any albinism Sharks?

In a paper published in March in the Journal of Fish Biology, she described the first record of albinism in lantern sharks, a group of deep-sea sharks, in a Lucifer’s shark collected about 30 years ago. “I saw this little lantern shark sitting there and was like, ‘What the hell is that?” she said. “It had no pigmentation whatsoever.”

Can Iridescent sharks be bred in captivity?

Due to their large size and strange breeding behavior, Iridescent Sharks have not been successful bred in captivity. Iridescent Sharks are native to the Mekong basin, Chao Phraya River, and Maeklong basin. Although they are actually catfish, it is their shark-like appearance that has made them popular among fishkeepers.

Where can you find Iridescent sharks?

You can find iridescent sharks scattered throughout Southeast Asia. They’re a tropical freshwater fish that tend to stick to deep and wide rivers where they have enough room to roam freely. They are condensed in two of the largest rivers in Southeast Asia, the Mekong, and Chao Phraya.

What are photophores in sharks?

Fin spines and rays, lateral line scales, and gill rakers are commonly analyzed characteristics, but photophores in many deep water species, or teeth in shark species, may also be observed, for example.

Are there albinos in deep-water sharks?

While little is known about these albinos — only a handful of individuals from a handful of species have ever been observed by researchers — occasional specimens are making marine biologists wonder how a lack of pigment may affect deep-water sharks, as well as their relatives rays and chimaeras (sometimes called ghost sharks).

Are there any sharks that are albino?

In the class Chondrichthyes, several species of naturally occurring albino rays and sharks have been recorded. Furthermore, an albino individual spotted ratfish ( Hydrolagus colliei) from the order Chimaeriformes has been reported. Albinistic individuals of the following shark species have been reported:

How common is albinism in fish?

The incidence of albinism can be artificially increased in fish by exposing the eggs to heavy metals (e.g. arsenic, cadmium, copper, mercury, selenium, zinc). In the wild, albinism is reasonably common in the teleosts, especially the Pleuronectiformes (flatfish), however, it is rarely reported in the elasmobranchs.

What are some examples of albino fish?

Several types of aquarium fish have “albino” in their names, e.g. albino driftwood catfish, albino festivum, albino red tailed shark, and albino tiger shark, however, photographs of these four fish indicate that the latter three have dark eyes and/or pigmented fins.

Are there albinos in the world?

Forget the white whale — some of the most rarely seen albinos on the planet are deep-water sharks that spend most of their lives in a world without light. “It’s not common, that I’m aware of, in any particular shark or ray group,” said David Ebert, director of the Pacific Shark Research Center of the Moss Landing Marine Laboratories in California.

What is the function of the photophores in fish?

Every species has a unique arrangement and distribution of photophores on their body, which help the fish to recognize species of same type and thus help in schooling behaviour. The luminous organs are also helpful in recognizing the mates for courtship, as the light organs may be different both in male and female.

What animals have photophores?

Photophores are found on some cephalopods, including firefly squid, the sparkling enope or firefly squid, which can create impressive light displays, as well as numerous other deep sea organisms such as the pocket shark Mollisquama mississippiensis and the strawberry squid.

What is the function of the lens in a shark?

Lantern sharks possess thousands of relatively simple tiny photophores where light is produced in small clusters of photocytes (photogenic cells). Light is transmitted to the outside through lens cells separated from the photocytes by a pigmented iris-like structure used for a mechanistic light regulation.

What is the function of the photophores in lanternfish?

Lanternfish (Symbolophorus barnardi) The photophores are located on the fish’s head, underside, and tail. It is believed that these light organs are used to attract other small fish on which the lanternfish feeds. They may also be used to signal other lanternfish during mating.

Can albino fish survive without pigmentation?

Even less is known about the rare albino specimens that pop up, and how their lack of pigmentation may affect their survival, fitness, or ability to mate. “The deep sea is horribly underexplored,” he said.

Is there such a thing as an albino dogfish?

The albino lucifer’s dogfish found by Dr. Brit Finucci is the first record of albinism in the lanternshark family, Etmopteridae. [Photo: Brit Finucci, NIWA]

Are there albino Sharks in the world?

“After looking through some literature, I couldn’t find anything that reported albinism in the lanternshark family, Etmopteridae, so it was a new record. We can’t say for certain how many sharks are albino because the deepsea is so understudied, but it is a rare occurrence,” says Dr. Finucci.

What animals are affected by albinism?

Albinism is known to affect mammals, birds, fish, reptiles, and amphibians. In marine mammals, anomalously white individuals have been reported for 21 cetacean species (Fertl et al., 1999; Fertl et al., 2004) and 7 pinniped species (e.g., Rodriguez and Bastida, 1993; Bried and Haubreux, 2000) ( Fig. 2 ).

How does albinism occur?

In mammals, albinism occurs when an individual inherits one or more mutated genes from both parents that interfere with the body’s production of melanin, the main pigment that determines the color of skin, fur, and eyes.

What is albinism in horses?

Albinism is a congenital absence of normal pigmentation due to an autosomal recessive enzymatic defect preventing normal production of melanin from melanocytes. Affected horses lack pigment in hair and skin and may have pink irides.

What is the relationship between albinism and family history?

An individual with albinism is more likely to have a family history of albinism than someone with the pigmented allele, so examination of albinism families that are very large and have maintained good records on family history can offer clues.
