Cotton Top Tamarins are recognisable by their mottled gray-brown shoulders, back and rump. The hair on the back of their thighs and the base of their tail is red-brown and they have a fan of long, white hair on their heads. Their nails are claw like.
Cotton Top Tamarins have fragmented populations in Northwest Colombia
They are an omnivore; eating large amounts of insects, fruit and plant matter, tree sap, gum, nectar, small reptiles and nuts
Cotton Top Tamarins practice monogamous breeding systems where mating only occurs between the dominant male and female. Breeding is seasonal occurring from January to June. Fathers assist with births and carry the young when not being nursed by the mother. Sub-adults will assist in carrying and caring for young
They are a social animal, living in small family groups of up to 15, usually consisting of a dominant breeding pair. Unique cooperative structure allowing sub-adults to gain breeding experience by assisting the dominant pair raise young, before breeding themselves
Habitat loss due to deforestation for agriculture and pasture. Illegal pet trade
Critically Endangered” due to habitat loss and the pet trade
Silvery Gibbons inhabit the isolated pockets of primary rainforests on the western side of Java, live in monogamous family groups consisting of the parents and up to 4 immature offspring. Silvery Gibbons are strictly arboreal and rarely descend to the forest floor.
Adaptations in their wrists and shoulders support them when brachiating through the forest canopy.
The female’s loud call and song early in the morning acts to defend their territory.

Body hair is grey all over with a dark hairless face with light grey eyebrows. Arms and fingers are long with reduced thumbs.
Fragmented populations in the western half of Java
Mainly frugivorous, they also eat leaves, flowers, nuts and insects.
A single offspring is born after a gestation period of 210 days. Birth interval is 2-3 years. Sexual maturity is reached between 5-7years. Average lifespan in the wild is 35 years. Gibbons in captivity can live up to 50 years.
Social, living in family units of up to 6 individuals. Groups consist of a dominant male and female breeding pair and their immature offspring.
The biggest threat to the survival of Silvery Gibbons is habitat loss and human encroachment. Less than 4% of their original habitat exists and is still on the decline. The illegal pet trade and poaching is another ongoing threat.
Silvery Gibbons are a seriously endangered species , Mogo Zoo is proud to be one of a handful of institutions who, under the watchful eye of a globally run Breeding Program has managed to produce offspring. We support the ‘Silvery Gibbon Project’ based at Perth Zoo in an effort to rescue and rehabilitate Silvery Gibbons on the island of Java.
The smallest of the Surviving Tiger subspecies, the Sumatran Tiger’s Coat is orange and black striped with a whitish underside and white beard. They have whiskers, long ears, and are small with dark ‘predator spots’.
Sumatran tigers are territorial; living in home ranges in which they maintain several dens. They hunt at night as they are nocturnal animals.
Number of offspring: 2 – 4 cubs every 3 – 4 years
Gestation: 90 – 110 days
Maturity: 3 – 4 years
Lifespan: 10 – 20 years
Predators: No true natural predators
Tigers Carnivorous; eating fish, crocodile, pig, deer, fowl
Females come into estrus every 3-9 weeks and mating can occur year round with no specific breeding season.
Cubs are helpless at birth and eyes do not open for 1-2 weeks. Females nurse and care for dependent young until they can hunt for themselves at 18-36 months.
Tiger Social structures
Solitary; males control a territory with a number of females. Females can often be seen with their most recent offspring for up to 3 years.
If you’d like to get up close to a Tiger, Mogo Wildlife Park has a Tiger encounter available.
Tasmanian Devils are the largest living carnivorous marsupial, standing at 80-90cm in height and weighing anywhere from 6-14kgs. They have thick black fur, with fleshy pink ears and snout, and a white strip of fur running across their collar bone from shoulder to shoulder. They have shorter hind legs than front legs, and a strong, powerful jaw with large canines top and bottom.
Tasmanian Devils are carnivorous opportunistic scavengers, feeding on the carcasses of medium-large vertebrates such as mammals and birds, as well as large invertebrates. They will gorge themselves on meat, consuming up to 40% of their own body weight in one feed. There may be a small group of individuals feeding on the one carcass at once.
Tasmanian Devils are primarily solitary animals, living in territories that may intersect other individual’s territories. Each territory will have 3-4 dens, which can be utilised for years, especially by females with young. In the weeks leading up to oestrus, females will develop a fat roll on the back of their neck, and will slowly decrease their food intake. Mating rituals involve males fighting over a female, with the victor then attempting to “woo” the female. The male and female will exchange vocalisations and re-enact the male-male fighting, without causing actual harm. Once a male has convinced a female that he is strong enough and genetically fit, he will bite the fat roll on her neck and drag her to the den for mating. Copulation can last anywhere from 12 hours to 5 days, with the male resting to watch the opening to the den in case of other males. A female can mate with several males in one breeding cycle, and males will mate with as many females as possible to ensure their genetics continue. After a gestation period of around 21 days, a female will give birth to up to 40 joeys. Only a maximum of 4 joeys will survive, as the female only has 4 teats in her pouch. All unsuccessful joeys are eaten by the mother for protein. The joeys will develop in the pouch for approximately 16 weeks, and are then placed in the den where they will dig their own side-dens for protection against other devils and predators. At 36 weeks of age, joeys are independent and will leave the den shortly after.
In the wild, Tasmanian Devils suffer from a terrible and deadly disease called “Devil Facial Tumour Disease” (DFTD). This disease causes large, painful tumours to develop on the Tasmanian Devil’s face and neck, disabling them from eating or drinking. Within 3 months an infected individual will most likely starve to death. The disease is transmitted primarily through saliva when biting.
