In this article, we will be talking and learning about one of the most fascinating creatures that inhabit our oceans, the bumphead parrotfish. The bumphead name comes from the fact that they use their large foreheads to ram into coral to help them to feed on algae and live coral. They have quite a few other names such as bumpheads, humphead parrotfish, giant parrotfish, buffalo parrotfish, and also double-headed parrotfish. You can always come across this keystone species while you scuba dive. It maintains the marine ecosystem by keeping a check on algae growth on coral reefs since algae is a big part of the bumphead's diet. Found in small aggregations, these fish are often victims of overfishing which has caused their population to dwindle.
Read on to the very end of this article to learn about the wonders of the bumphead parrotfish fish. If you enjoy reading this article, make sure you check out American shad and white tuna.
Bumphead parrotfish (Bolbometopon muricatum) is the largest species of parrotfish.
Bumpheads, with the scientific name Bolbometopon muricatum, belong to the class Actinopterygii. Furthermore, bumpheads belong to the family Scaridae and genus Bolbometopon.
Bumpheads (Bolbometopon muricatum) are listed as Vulnerable in the IUCN (International Union of Conservation of Nature Red List of threatened species. The exact number is not known, but the trends suggest that their population is decreasing.
The bumphead parrotfish (Bolbometopon muricatum) inhabit oceans. More specifically, bumphead parrotfish live close to coral reefs. They cover regions in both the Indian Ocean and Pacific Ocean. To the south, they are commonly spotted along the Great Barrier Reef of Australia, and they are also found in the Red Sea.
While adult humphead parrotfish can be found in deeper waters, juveniles are found in shallower waters with seagrass beds. Humphead parrotfish may linger around in dark sea caves or wreckage of sunk ships.
Humphead parrotfish live in small schools, but at times this group may exceed 75 individual fish in ideal habitat regions of clear lagoon reefs.
A bumphead's life span is up to 40 years. Bumpheads grow slowly and take about three years to mature and grow slowly.
There is courting behavior observed in the bumphead parrotfish during the early mornings of the lunar cycle. Green humphead parrotfish mate in a large, tightly packed group of about 100 fish. Males release sperm, and females release the eggs in open water. The fertilized eggs lead to the development of larvae which is at the mercy of the currents. It takes about three years of feeding in shallow lagoons for juveniles to join the adults in deeper waters.
Interestingly, most humphead parrotfish are born as a female. Males, too, have hermaphroditic features. When the dominant male that leads the group dies or leaves, one of these hermaphroditic females will go through physiological changes to become a male and take over as the dominant fish.
The humphead parrotfish is listed as Vulnerable on the IUCN (International Union of Conservation of Nature) Red List. The primary reason for their decreasing rate is over-fishing. Scuba-assisted spearfishing, as well as commercial fishing, almost brought the species to extinction in Fiji. The fact that these fish take a while to mature and reproduce also makes it difficult to revive their population with ease. Many island nations and island communities are enforcing laws to make sure that these fish continue to thrive in our oceans. Unfortunately, It hasn't yet been possible to go to the length of outright banning their hunting.
These fish are large in both size and mass. As the name suggests, the most distinguishing feature of this fish is its bulbous foreheads. Their teeth are exposed and look like a beak. Their scales are colored dull gray and green. A male and female are indistinguishable from each other.
Whether you would call them cute is really up to you. One may find their bulbous heads intimidating, others may find exactly that feature endearing. Yet, their exposed teeth plates do not give them the most pleasant appearance.
It is not yet known the extent to which these fish interact with each other. Scientists are observing their behavior in many coral reefs to understand how they communicate.
The green humphead parrotfish is the biggest species of parrotfish, both with respect to mass and length. Bumpheads may be as long as 4.2 ft (1.28 m) in length and may weigh about 100 lb (45.3 kg). Blue whales are 25 times bigger than this species.
The green humphead parrotfish uses its pectoral fins to swim. There is no reliable observation of how fast they can swim.
The green humphead parrotfish is the heaviest species of parrotfish, weighing in at about 100 lb (45.2 kg)
There are no unique names given to the male and female humphead parrotfish. Notably, almost all fish of this species start off as female and change their sex if the dominant 'supermale' dies or leaves.
There is no separate name for baby bumpheads. Although you can refer to them as larvae right after bumpheads hatch and as they develop into adults, you may call them juvenile humphead parrotfish.
Green humphead parrotfish feed on algae that grows on the coral. Bumpheads use their pharyngeal teeth to grind their food, that is, algae and coral, into a paste. This fish digests the algae, and the rest of the coral is converted into tons of sand-like sediment, passed out as poop. It is this sediment that makes up part of the white sand on the beaches you so love to walk on and feel on your feet.
This fish is not particularly dangerous, although they do ram their head really hard into coral reefs. They also have exposed teeth that may look threatening. Despite that, they do not pose any serious threat to humans or any other fish in general too. In fact, parrotfish can be eaten and is a delicacy in Jamaica.
The green humphead parrotfish is a creature that roams freely in the oceans feeding on reefs. It is hard and perhaps cruel to keep them as pets. You may be able to spot bumpheads in the wild if you get a chance to visit the Great Barrier Reef in Australia, Yaeyama Island, or in an aquatic life zoo.
The sediment that comes from the poop (excreta, to be more scientifically appropriate) of the parrotfish makes up a significant percentage of the white sand that is found on any white sand beach around the world. This is because of the fact that the parrotfish, like the bumpheads, feed on a few tons of coral reef carbonate every year which they are unable to digest.
Bumpheads and the parrotfish, in general, play a crucial role in the marine ecosystem. Their diet consists of large volumes of algae and live coral, so they eat the reefs which have algae on them. This dietary choice helps coral reefs stay healthy and clean. By feeding on the algae that competes with the coral, they are able to help the reefs thrive. It must be noted that coral which has algae growth on is eaten by parrotfish. This is not too much a threat to the coral health because had the algae growth been left unchecked, it would've been bad for the coral reef and consequently sea and marine life at large.
Many species of parrotfish cover themselves in a mucus cocoon to hide from their predators as they are sleeping in coral caves. This cocoon helps them hide from predators both visually and by masking their scent. These predators may not be as big and scary as sharks but they are parasites that suck the blood of parrotfish. You could say these fish species make their own blankets of sorts while sleeping.
