Biological Profile & Identification

The Loggerhead Sea Turtle (Caretta caretta) is distinguished by its disproportionately large, muscular head and powerful crushing jaws, engineered by nature to crush hard-shelled benthic prey such as horseshoe crabs, conchs, clams, and sea urchins. It represents the primary sea turtle species inhabiting the Mediterranean Sea and temperate Atlantic coastal zones.

Key Anatomical Characteristics

  • Massive Heavy Head & Thick Neck: Reddish-brown, heart-shaped shell with thick scutes and large head scales.
  • Five Pairs of Costal Scutes: Unlike Green turtles (4 pairs), Loggerheads have five distinct lateral scutes along each side of the carapace.
  • Coloration: Rich copper-red to reddish-brown carapace with a pale yellow plastron (underside).
