Did you know that there are five species of rhino? There are two African rhino species (white and black rhinos), and the remaining are Asian rhino species (Indian, Sumatran, and Javan).
White Rhinoceros (Ceratotherium simum): White rhinos are the largest rhino species, with two horns, the front one usually longer. They live in southern Africa, mainly South Africa, Namibia, Zimbabwe, and Kenya.
Black Rhinoceros (Diceros bicornis): Black rhinos have pointed upper lips and two horns. They are more solitary and aggressive behavior compared to the white rhino. Historically, black rhino populations ranged across much of sub-Saharan Africa. Still, due to poaching and habitat loss, their numbers have drastically declined, and they are now mainly found in eastern and southern Africa.
Indian Rhinoceros (Rhinoceros unicornis): The Indian rhinos, or greater one-horned rhinos, are the second-largest rhino species and have a single horn. They live in grasslands and swamps in Nepal and northeastern India.
Sumatran Rhinoceros (Dicerorhinus sumatrensis): The Sumatran rhino is the smallest and most critically endangered rhino species. They have thick, reddish-brown hair and two horns. Their populations scatter across fragmented forests in Indonesia (Sumatra and Borneo) and Malaysia.
Javan Rhinoceros (Rhinoceros sondaicus): The Javan rhino is the world's most critically endangered mammal and has a single horn, typically shorter than the Indian rhino's horn. Javan rhinos are found only on the island of Java in Indonesia (specifically in Ujung Kulon National Park), with a tiny population also existing in Vietnam's Cat Tien National Park.
Rhinos rank second as the largest and heaviest terrestrial animal. The white rhino tips the scales at 5,000 pounds. The smallest rhino species is still significantly large and weighs around 1,870 pounds.
Though confusing, the names of white and black rhinos don't reflect their actual color. The 'White Rhino' name resulted from a quirky misunderstanding by early English settlers in South Africa. They misheard the Afrikaans' wyd' (meaning 'wide') as 'white' when referring to the animal. However, 'wyd' actually referred to the rhino's wide, flat mouth.
Meanwhile, the 'Black Rhino' received its name as a simple contrast to the 'White Rhino,' not because of color differences. Some speculate that this may be due to their tendency to roll in mineral-rich mud, making their skin appear darker.
You read that right. The Indian Rhino is semi-aquatic and a gifted swimmer. They thrive in habitats near water sources, such as marshlands, grasslands, and alluvial floodplain forests. The Indian Rhino uses water as a defense mechanism to escape potential threats. Swimming also allows them to move between different areas and access abundant vegetation, including aquatic plants, reeds, and grasses growing near the water.
Did you know that rhinos use their poop to communicate important information1? The distinctive scent in their feces contains chemical signals that convey their sex, age, reproductive status, and territorial boundaries. When one rhino encounters these scent markings, it can learn crucial details about the other rhino, helping it to assess potential mates or rivals and avoid unnecessary conflicts.
In addition, rhinos also use vocalizations, body language, and physical interactions to communicate with each other. Grunts, snorts, and trumpeting vocalizations serve various social purposes, including mating displays, warning signals, and expressions of distress. Physical interactions, such as headbutting and body leaning, also help rhinos establish dominance, hierarchies, and social bonds within their community.
Rhinos have one of the longest gestation periods in mammals. They give birth to their calf after 15 to 16 months. The reason? This extended period is likely because they carry a much larger baby that requires more time and energy to develop. A newborn rhino calf can weigh between 88 to 140 pounds. Typically, rhino babies stay with their mothers for up to three years.
Their tenacity allows them to see decades, living an average of 40 to 50 years. This is even true in harsh conditions where these sturdy creatures face intense heat, droughts, and fluctuating food supply. Evolution has gifted them with adaptable digestive systems, letting them make do with dry grass and shrubs during lean times.
Then there are our captive rhinos. Here, they find themselves tucked away from danger, living under the vigilant eyes of caretakers. In zoos and sanctuaries, rhinos live even longer, reaching up to 60 years. Regular meals, clean water, and timely medical intervention are pivotal in extending their lifespan. Yet, while their days may be longer, it's crucial to remember that the safety of captivity can never substitute the vibrancy and diversity of life in the wild.
Did you know that African rhinos have a unique relationship with oxpeckers? These birds, sometimes called "tick birds" or "cleaner birds," are helpful companions to rhinos by providing grooming services. They eat ticks, parasites, and insects that infest rhino skin.
Additionally, oxpeckers serve as guards for rhinos, warning them of danger with their sounds since rhinos have poor eyesight. In exchange for their services, rhinos offer oxpeckers a reliable food source and a safe place to perch4.
Although the dry season extends from May through October, the driest period is in the cool mid-winter months. Temperatures are at their most pleasant, with warm days, low humidity, and virtually no rainfall. Mid-day temperatures average a very pleasant 79°F (26°C) in mid-winter, with deep-blue cloudless skies. However, nighttime temperatures fall dramatically. Early morning temperatures just before sunrise average about 50°F (10°C), and are often much colder.
