What are the adaptations of a cod?

- Body shape: Cods have a streamlined, fusiform body shape, which reduces drag and allows for efficient swimming in the water.

- Fins: Cods have two dorsal fins, one located near the middle of the back, and the other located closer to the tail. These fins provide stability and maneuverability while swimming. The pectoral fins are located on either side of the body and help with steering and balance. The pelvic fins near the belly are essential for maintaining stability and maneuvering in the water.

- Scales: Cods are covered in small, overlapping scales that provide protection from external factors and reduce friction during swimming.

- Swim bladder: Cods have a swim bladder, a gas-filled organ that helps them maintain their position at different depths in the water without expending too much energy. By adjusting the gas volume in the bladder, cods can control their buoyancy and depth.

- Gills: Cods breathe dissolved oxygen from the water through gills. Their gills are composed of filaments with a large surface area covered in blood vessels, which allows efficient oxygen uptake.

- Sensory organs: Cods have a series of sensory organs that allow them to perceive their surroundings and detect potential predators, food, and other environmental cues. Their eyes are well-adapted for vision in low-light conditions, and they also have a lateral line system on the sides of their body that detects water currents, vibrations, and pressure changes.

- Cold adaptations: Cods are cold-adapted fish that can survive and thrive in low temperatures. They have specific proteins in their blood and tissues that prevent them from freezing in icy waters.

- Reproductive strategies: Cods have high fecundity, with females producing millions of eggs at a time. This reproductive strategy helps ensure that some offspring survive despite the challenging marine environment and predators.
