What adaptations have allowed the marine toad to thrive?

• A. Bright coloration to deter predators.
• B. Ability to fly between habitats.
• C. A robust body, tolerance for varied habitats, and a diet that supports success in multiple ecosystems.
• D. Strictly aquatic lifestyle.

Answer: (C)

The main idea is that thriving in many environments comes from being versatile: a strong body that can handle different terrains, the ability to live in a range of habitats, and a flexible diet that lets you find food in multiple ecosystems. The marine toad uses all three: its robust body helps it move across land and survive heat and dryness; it tolerates a variety of habitats—from forests to farmland to urban areas—so it can colonize new places easily; and it eats many different prey, so it isn’t dependent on a single food source. This generalist strategy makes it successful as an invasive species and explains why it can spread so widely. Bright coloration isn’t a hallmark of this species and isn’t the reason it thrives. Flying isn’t possible for a toad, so that ability wouldn’t contribute to its success. Being strictly aquatic would limit its spread and survival in drier or different environments, which contradicts how the marine toad actually behaves.
