Marine iguana

The sea iguana, found only on the Galapagos Islands, is the only lizard that ventures into the ocean to feed. It dives underwater to graze on algae, its primary food source, and spends much of its time basking on rocky shores to warm up after chilly swims.

• They are the only lizards that forage in the sea.
• Large males dive for algae, while smaller ones feed at low tide.
• Females lay eggs in soil nests, leaving them to hatch alone.
