Barb

Barb

Barb are a small sized group of fish that are naturally found in the freshwater rivers and lakes across the southern hemisphere. There are over 2,000 known species of barb in the world inhabiting the frehswater regions of Asia, Africa and South America.

The barb fish is often referred to as a freshwater shark, due to the fact that barb are one of the few species of freshwater fish to have rows of teeth in their mouths. Despite their small size, barbs are known to be ferocious hunters and are dominant predators in the world of small fish in their natural environment. Barb do only prey upon the fish that are smaller than them, but also on medium sized fish that can sometimes be double the size of the barb.

Due to their small size and bright colours barb are commonly kept in household aquariums worldwide. The most common barb kept in aquariums are the cherry barb (pink/red in colour) and the tiger barb (silver body with thick, black stripes and red fin on it's belly) .

Barb are known to be relatively hardy fish and can easily adapt to changes in the water including changes in pH levels and temperate. It is known that barbs can successfully inhabit unheated tanks, and although this has proved to be successful in many cases, it is not recommended as barb are naturally found in warmer tropical waters.

Due to their aggressive and dominant nature, it is not ideal to keep barbs in artificial tanks with smaller species of tropical fish. At the same time, barb will also hunt medium sized fish if there is a lack of food, and so are best kept on their own (just barbs) or with much larger species of fish.

Barbs are known to lay numerous eggs in order for a few to hatch successfully. The baby barb are called fry and generally hatch within a few days of being laid. Like their hardy barb parents, the barb fry are able to adapt well to changes in their surroundings.

Barbs are opportunists and will therefore eat almost anything that they can find. Although barbs prefer a predominantly meat based diet that includes smaller fish, insects and bloodworm, barb are also known to eat aquatic plants particularly those that are softer and therefore easier to ingest. The exact diet of the barb however, depends on the species and the region in which it inhabits.

Angelfish

 Angelfish

There are around 100 different species of angelfish that inhabit the waters of the southern hemisphere. There are two main types of angelfish, those that live in the freshwater rivers in South America (freshwater angelfish) and those angelfish that inhabit the salty ocean waters (marine angelfish).

The freshwater angelfish has a more triangular shape and will generally only grow to a few inches in length. The marine angelfish can grow up to 12 inches (the same length as a big ruler) and generally have very brightly coloured markings but the exact colours depend on the angelfish species.

Both the freshwater angelfish and the marine angelfish are known to be relatively difficult fish to keep in household aquariums, as both types of angelfish require very specific water conditions. Angelfish are very susceptible to changes in the water such as salt levels and pH levels, and will often die if changes are too drastic.

Despite the fact that their names are the same, freshwater angelfish and marine angelfish are not thought to be closely related. The freshwater angelfish is a tropical species of cichlid, distantly related to the cichlids found in specific lakes in Africa. The marine angelfish are believed to be most closely related to the butterfly fish.

Freshwater angelfish are native to the Amazon basin and are also found in the rivers running off it. Freshwater angelfish inhabit the cleaner waters and prefer to be in temperatures between 25 and 30 degrees centigrade.

Freshwater angelfish lay between 100 and 1,000 eggs which hatch in just a couple of days. Freshwater angelfish tend to lay their eggs on a flat leaf or an underwater log. The baby angelfish (known as fry) remain attached to the eggs for another week and feed off the remaining yolk in the egg sack. When they are bigger at a week old, the angelfish fry detach from their eggs and become free swimming. It is at this stage that the baby angelfish begin feeding from nutrients in the water and on plants.

The triangular shape of the freshwater angelfish, means that the angelfish is able to hide more easily amongst the aquatic plants in the water. Wild freshwater angelfish have very distinctive dark stripes that run vertically down their bodies, giving the freshwater angelfish the ability to blend in to it\'s surroundings. Freshwater angelfish usually breed for life and it is often found that if one of the angelfish parents dies, then the remaining angelfish parent has no interest in breeding.

Freshwater angelfish feed on smaller fish and invertebrates in their natural environment as well as eating particles of food found in the water. The freshwater angelfish is preyed upon by larger species of fish, birds and marine mammals.

Marine angelfish are generally found in shallow reefs in depths of up to 50 meters. Marine angelfish are reported to be almost fearless and are noted to be inquisitive and curious towards divers. Some species of marine angelfish are solitary by nature where other species of angelfish form territorial mating pairs or even groups. The groups of marine angelfish usually have one male and a number of females.

Unlike the freshwater angelfish, marine angelfish lay their tiny eggs straight into the water. The angelfish eggs float in the sea, becoming mixed in with the plankton, until they hatch. Unfortunately a vast number of marine angelfish eggs are inadvertently eaten by those many animals that feed on the plankton in the water.

Marine angelfish are most well known for the bright colours and patterns on their bodies. Marine angelfish vary in colour and size depending on the species of marine angelfish, although it is known that the patterns and colours of marine angelfish change drastically as they get older. It is believed that these colour changes indicate the position of the marine angelfish, within the marine angelfish social hierarchy.

Marine angelfish graze on algae on coral reefs and rocks are well as eating smaller fish and crustaceans such as shrimp and small species of prawn. Adult marine angelfish are preyed upon by sharks, marine mammals and humans, but the young and smaller marine angelfish are eaten by many different species of animal both in the water and those based on land (such as birds).

The Lion

THE LION

The lion (Panthera leo) is one of the five big cats in the genus Panthera and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies found in Africa. With some males exceeding 250 kg (550 lb) in weight,[4] it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in Asia (where an endangered remnant population resides in Gir Forest National Park in India) while other types of lions have disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru.The lion is a vulnerable species, having seen a major population decline in its African range of 30–50% per two decades during the second half of the 20th century.[2] Lion populations are untenable outside designated reserves and national parks. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are currently the greatest causes of concern. Within Africa, the West African lion population is particularly endangered.

In the wild, males seldom live longer than 10 to 14 years, as injuries sustained from continual fighting with rival males greatly reduce their longevity.[6] In captivity they can live more than 20 years. They typically inhabit savanna and grassland, although they may take to bush and forest. Lions are unusually social compared to other cats. A pride of lions consists of related females and offspring and a small number of adult males. Groups of female lions typically hunt together, preying mostly on large ungulates. Lions are apex and keystone predators, although they are also expert scavengers obtaining over 50 percent of their food by scavenging as opportunity allows. While lions do not typically hunt humans, some have. Sleeping mainly during the day, lions are active primarily at night (nocturnal), although sometimes at twilight (crepuscular).

Highly distinctive, the male lion is easily recognised by its mane, and its face is one of the most widely recognised animal symbols in human culture. Depictions have existed from the Upper Paleolithic period, with carvings and paintings from the Lascaux and Chauvet Caves, through virtually all ancient and medieval cultures where they once occurred. It has been extensively depicted in sculptures, in paintings, on national flags, and in contemporary films and literature. Lions have been kept in menageries since the time of the Roman Empire, and have been a key species sought for exhibition in zoos over the world since the late eighteenth century. Zoos are cooperating worldwide 

in breeding programs for the endangered Asiatic subspecies.
