Coelacanths are able to survive changes in temperature and pressure due to their physiologically unique swim bladder, which allows them to control their buoyancy in deep waters. They also have a highly efficient metabolism that allows them to conserve energy in low-oxygen environments. Additionally, they are able to regulate their body temperature by using the heat generated by their muscles during sustained swimming.
Coelacanths are adapted to living in deep-sea environments with high pressure and low temperatures. They have several physical adaptations, such as a specialized swim bladder filled with oil that helps them maintain neutral buoyancy, and a slow metabolism that allows them to conserve energy in low-oxygen environments. They are also able to regulate their body temperature internally through a system of blood vessels that conserve heat.
Coelacanths are known for their ability to inhabit deep-sea environments, which subject them to extreme changes in temperature and pressure. They have several adaptations to cope with these conditions:
1. Low Metabolic Rate: Coelacanths have a relatively low metabolic rate, which allows them to conserve energy in the cold and dark deep-sea environment where food is scarce.
2. Insulation: Their thick, oil-filled scales provide insulation and help maintain a stable body temperature.
3. Pressure Tolerance: Coelacanths have specialized adaptations in their swim bladder and other internal structures that help them cope with the high pressure of the deep sea.
4. Slow Swimming: They are slow swimmers, which reduces the amount of energy they need to expend and helps them conserve oxygen in low-oxygen deep-sea habitats.
Overall, coelacanths have evolved to thrive in the specific conditions of their deep-sea habitat, where temperature and pressure can vary significantly from the surface.

Coelacanths are fascinating fish with several unique adaptations that allow them to survive in the deep ocean environment:
Lobed Pectoral Fins: One of the most distinctive features of coelacanths is their lobed pectoral fins, which resemble limbs. These fins are thought to aid in their stability and maneuverability in deep waters.
Jointed Skull: Coelacanths have a jointed skull, which allows them to widen their mouths widely when feeding. This adaptation helps them capture prey more efficiently in the darkness of the deep sea.
Electroreception: Coelacanths have an organ in their snout called the rostral organ, which is believed to be electroreceptive. This means they can detect weak electric fields produced by other organisms, helping them locate prey and navigate in low-light conditions.
Fatty Liver: Coelacanths have a large, fatty liver that helps them maintain buoyancy in the water. This adaptation is common among deep-sea fish and provides them with a stable position in the water column.
Slow Metabolism: Coelacanths have a slow metabolism compared to other fish. This characteristic allows them to survive on a limited amount of food, which is essential in the nutrient-poor environment of the deep sea.
Scale Thickness: Their scales are thick and tough, providing protection against the high pressure of the deep ocean.
These adaptations collectively enable coelacanths to thrive in the deep sea, where they are thought to primarily feed on fish and cephalopods. Despite their ancient lineage and unique features, coelacanths are considered living fossils because they have remained relatively unchanged over millions of years, offering valuable insights into the evolutionary history of vertebrates.
