Range of the brownbanded bamboo shark

The brownbanded bamboo shark (Chiloscyllium punctatum), is a bamboo shark in the

public aquaria, and is arguably one of the sharks most suited to captivity due to its docile disposition, sedentary nature, and relatively small size. In public aquariums, these fish can live up to 25 years.[1]

Features

Juvenile

These sharks can be distinguished by their concave posterior margined dorsal fin. No color patterns are present for the adults, however, the juveniles have dark transverse bands with some dark spots.[2] It can grow up to 1.04 metres (41 in).

It is a nocturnal animal and can survive out of the water for up to 12 hrs. They have

wobbegongs, epaulette sharks and whale sharks, belonging to the family Orectolobiformes
.

Habitat

These sharks live around coral reefs and tide pools. It resides at depths down to 85 metres (279 ft).

Sharks as pets

The minimum size of the tank that can carry an adult cat shark is about 180 gallons. Because these sharks are

puffers; they will nip at the shark's fins, nor should they be placed with aggressive feeders.[4]

Reproduction

It reproduces

oviparously
.

Feeding

These sharks are carnivores that should be fed 2-3 times a week; some of their diet includes fresh

goiter disease, they should take iodine supplements. Two things to be aware of when feeding the shark: one is to make sure that the meals are bite sized or else it will throw it back up and the second is sometimes juveniles are difficult to get to eat so adding a flavor enhances their interest .[5]

DNA

In 2018, a group led by Shigehiro Kuraku published a draft assembly of the

Nature Ecology & Evolution.[6] In this study, the brown-banded bamboo shark genome was sequenced and assembled using DNA samples provided by a Japanese aquarium, Osaka Aquarium Kaiyukan. It was sequenced using Illumina sequencing
technology and assembled using a short read genome assembler. According to their analysis, the genome size is estimated to be 4.7 giga base-pairs.

The slow molecular evolutionary rate of

elasmobranchs (sharks, rays and skates) has been reported repeatedly.[7] Despite such slow evolutionary nature, it was once reported that elasmobranchs probably lost HoxC cluster, one of the four Hox gene clusters.[8]
However, the genome sequence of the brown-banded bamboo shark revealed the existence of several Hoxc genes.

Threats

Its minimum population doubling is in the 4.5–14 years range.[9] The major threats to these sharks are the loss of their habitat, pollution, and capture (both for aquarium trade as well as food).[10]

In popular culture

The main protagonist of the 2012 Malaysian animated feature film SeeFood is a talking, sentient young brownbanded bamboo shark named Pup, whose ability to breathe on land plays a major role in the plot.[11]
