spiny puffer

Thân thiện

A spiny puffer swims near a colorful coral reef.

Definition

Noun: 1. A type of pufferfish characterized by having rigid or erectile spines on its body. These spines are a defensive feature, making the fish appear larger and more difficult for predators to swallow when it inflates itself with water or air.

Usage

• The spiny puffer is well-adapted for defense, as its sharp spines deter most potential predators.
• Divers should avoid touching a spiny puffer, as its spines can cause injury and some species may carry toxins.
• When threatened, the spiny puffer inflates into a spiky ball.

Advanced Usage

• The term is often used in marine biology and ichthyology to distinguish pufferfish in the family Diodontidae (porcupinefish) from those in the family Tetraodontidae, which typically have smoother skin or smaller, embedded spines.
• In aquarium trade contexts, "spiny puffer" may informally refer to certain freshwater or brackish water puffer species with pronounced spines, though true spiny puffers are primarily marine.
