LOGGERHEAD TURTLE

LOGGERHEAD TURTLE

NEWS: Warmer oceans, depleting food sources–> affecting the reproductive patterns, migration routes, and even body size of the Loggerhead turtle.

ABOUT

  • A species of oceanic sea turtle
  • Belongs to the family: Cheloniidae (hardshelled sea turtles)
  • “Loggerhead”àBecause of its: Very large head, strong jaw muscles (used to crush hard prey)
  • World’s largest hard-shelled turtle
  • Larger than: Green sea turtle (on average weight)
  • Second largest turtle overall after: Leatherback sea turtle (softshelled)

Key Feature:

  • Large head + powerful jaws
  • Hard shell (carapace)
  • Adapted for crushing shellfish
  • Loggerhead turtles use the Earth’s geomagnetic field for navigation
    • They sense magnetic fields like a natural GPS
    • Helps in: Long-distance migration, returning to nesting beach
  • Play a key role in maintaining marine ecosystem balance, controlling invertebrate populations
  • IUCN Status: Vulnerable

Climate Change Affects Loggerhead Turtles:

  • Rising sea temperatures → alters nesting cycles
  • Temperature-dependent sex determination
  • Warmer sand = more female hatchlings
  • Ocean warming → decline in prey availability
  • Changing ocean currents → migration disruption

Environmental Significance

  • Indicator of ocean health
  • Supports marine food chains
  • Maintains ecological balance
  • Protects coastal ecosystems
  • Also linked with: SDG 14 (Life Below Water)àMarine biodiversity conservation
