The panga is a type of machete commonly used in East Africa for various purposes. Some of its uses include:
1. Agriculture: The panga is commonly used for cutting grass, clearing brush, and harvesting crops in agricultural settings.
2. Construction: The panga is used for cutting and shaping wood, as well as for general construction work.
3. Cooking: The panga can be used for chopping vegetables, meat, and other food items in the kitchen.
4. Self-defense: In some regions, the panga is used as a weapon for self-defense.
Adaptations of the panga include its curved blade, which allows for efficient cutting and chopping motions, as well as its sturdy construction, which makes it durable and long-lasting. The handle of the panga is often made of wood or plastic for a comfortable grip, and the blade is typically made of high-quality steel for sharpness and durability.

Adaptations of Panga:
Morphology:
- Flattened body: Panga have a laterally flattened body, which allows for efficient swimming. - Dorsal fin with spines: The dorsal fin contains sharp spines for defense against predators. - Barbels: Panga have barbels around their mouths, which help them sense and locate food.
Physiology:
- Tolerant to low oxygen levels: Panga can survive in low-oxygen environments, enabling them to thrive in crowded aquaculture tanks. - High growth rate: Panga have a rapid growth rate, making them efficient for commercial aquaculture.
Behavior:
- Schooling: Panga are social fish that form large schools. - Bottom-dwelling: Panga are bottom-dwelling fish, preferring to swim near the substrate. - Omnivorous: Panga feed on a variety of aquatic plants, small fish, and invertebrates.
Other Adaptations:
- Respiratory adaptations: Panga have evolved specialized respiratory structures called "gill filaments" that allow them to absorb oxygen efficiently from the water. - Reproductive adaptations: Panga are capable of spawning multiple times throughout the year. - Disease resistance: Panga have developed certain immune mechanisms that help them resist common fish diseases.
