Home’s Hinge-back Tortoise

1 Overview

The Home’s hinge-back tortoise is one of the more difficult tortoises to keep—not because it gets sick easily, but because it is very shy, and unexplained sudden death is common. Keepers who are not mentally prepared should not attempt it lightly.

Chinese name: Home’s Hinge-back Tortoise

Also known as: Lotus-leaf hinge-back tortoise

Scientific name: Kinixys homeana

English name: Home’s Hinge-back Tortoise

Kingdom: Animalia

Phylum: Chordata

Class: Reptilia

Order: Testudines

Family: Testudinidae

Species: Home’s Hinge-back Tortoise (Kinixys homeana)

Diet: Omnivorous.

Appearance: Maximum carapace length 21 cm; a single caudal shield. Unlike other turtles, a hinge joint sits between the 7th and 8th marginal scutes, and the carapace slopes down sharply from the front edge of the 5th vertebral scute.

Habits: Mostly inhabits grassland and humid savanna, disliking overly damp areas.

Geographic distribution: Guinea, Liberia, Chad, Cameroon, Central African Republic.

Reproduction: Oviparous. Females usually lay 2–4 eggs per clutch, 2–3 clutches per year; eggs hatch after 110–130 days at 30°C.

Habits: Although distributed in Africa, they dislike strong light and need a large shaded area in captivity.

2 Physical Characteristics

The Home’s hinge-back tortoise, also called the lotus-leaf hinge-back, is a fairly common member of the hinge-back genus; species look very similar and are hard to tell apart. Below is an introduction to the genus classification and the species’ appearance.

1. Appearance

Adults have a carapace of 15–20 cm. The Home’s hinge-back closely resembles the African hinge-back and is easily confused with it; the key difference is that the rear of the carapace drops at a 90-degree right angle in the Home’s hinge-back, whereas the African hinge-back has a gentle arc—easy to distinguish with a little attention. Sex is told by the tail: thick tails are males, slender tails females. Females of the same age are slightly larger; males reach only 12–15 cm while females grow to about 20 cm.

2. Hinge-back Genus Classification

The hinge-back genus has six species; the most common are the Home’s hinge-back and the bell’s hinge-back. The others are the African hinge-back, and the rarer leaf-fold, barred, and Natal hinge-backs. All live in Africa and share the unique trait of a hinged rear carapace—distinctive among all turtles. The bell’s hinge-back has the widest range and largest numbers and is the representative species of the genus.

3 Care & Husbandry

The Home’s hinge-back tortoise has high care requirements; it is a species that tests both environment and feeding. It usually does not get sick, but sudden death often occurs for unexplained reasons, so owners can only do their best to protect it.

1. Care Points

The Home’s hinge-back is timid and easily stressed into refusing food, especially newly imported individuals. Basically all hinge-backs are unsuitable for beginners and are high-difficulty. Although African, they dislike strong light and need a large shaded area. Most are wild-caught and prone to internal and external parasites, so deworming is essential. Once adapted to a new environment, breeding and hatching them is not difficult.

2. Calcium Supplementation

The Home’s hinge-back can develop shell deformities or calcium-absorption problems. Besides using artificial lighting to establish a stable, regular physiological cycle, on warm, suitably humid days allow the tortoise some natural sunlight. Basking provides heat for normal digestion and physiology, and stimulates conversion of vitamin D precursors so the tortoise can fully absorb and use calcium.

4 Natural Habitat

The Home’s hinge-back has special temperature and humidity needs. Wild individuals mostly live in deserts, yet this is a desert-dwelling tortoise that dislikes desert climate; many owners try to recreate the native environment but often achieve the opposite effect.

1. Suitable Temperature

Although from hot Africa, it dislikes the dry, scorching typical desert. Many keepers thus create hot, dry conditions with heaters and lamps, which backfires. Within the hinge-back family, except the pancake tortoise which likes high heat, the rest prefer warm and humid conditions. For the Home’s hinge-back, keep daytime above 26°C, a basking spot at 32–34°C, and nights at 20–22°C.

2. Suitable Humidity

Most hinge-backs like humid environments; during hot days they often soak in pools to regulate body temperature. Keep good air circulation and relative humidity around 75%, and provide a shallow water dish or small pool for soaking.

5 Care Guidelines

The Home’s hinge-back has unusual environmental and dietary needs; it is not content with plants alone. In the wild it leans omnivorous, and in captivity many food types are suitable.

1. Diet

Although a tortoise, its environment and diet differ greatly from other African tortoises; closer to red-footed tortoise habits, it is a standard omnivorous tortoise. In captivity it can eat snails, insects, even organ meat as high-protein food, while plants can be moist soft fruit or leafy greens. Variety is key—monotonous food causes disease and nutritional excess or deficiency.

2. Feeding Recommendations

In the wild the lotus-leaf hinge-back eats widely, accepting almost any plant or animal food and needing relatively high protein—vegetables, fruit, weeds, snails, beetles. Fruit should be the staple. It also needs very high humidity, at least 80–90%; mist morning and evening, and a water dish is essential. Timid and easily stressed into refusing food, especially new imports, it is unsuitable for beginners and is a high-difficulty species.
