What Are Turtles?
Turtles are reptiles with four legs and a shell that shields them from predators. They can be sea turtles, land turtles, or turtles that inhabit freshwater environments like rivers, lakes, and ponds. Many turtles can live to a great age, with some exceeding 100 years. They tend to move slowly, but they are quite resilient, allowing them to thrive in challenging habitats.
Main Characteristics of Turtles
1. Shell as Protection
Turtles possess a hard shell on their back and belly. This shell is made up of bony plates fused with the spine and ribs. On top of these bony plates is a layer of tough horn scales, which is the same material that makes up our fingernails and hair. Since these creatures cannot effectively defend themselves against attackers, they rely on their defense mechanism. Most can retract their legs and head, leaving only the shell visible! However, not all turtles have a hard protective shell. Softshell turtles and leatherback turtles have only thin bony plates covered by a leathery, flexible skin.
2. Slow Movement
Land turtles are very slow, moving at only 0.1-0.3 mph (0.2-0.5 km/h). Freshwater turtles are also quite slow, reaching speeds of 0.6-1.2 mph (1-2 km/h). Only sea turtles are faster; the leatherback turtle can swim at speeds of up to 21.7 mph (35 km/h), making it the fastest reptile in the water.
3. Long Lifespan
Turtles are well-known for their impressive longevity, especially giant tortoises. The oldest turtle in the world lived to be 256 years old, making it the oldest reptile and land animal. Typically, most turtles live for around 50-100 years.
