Rhincodontidae
Rhincodontidae is a family of cartilaginous fishes that includes the whale shark, the largest known fish species. This family is the only one within the order Rhincodontiformes, and it consists of a single extant species, Rhincodon typus (whale shark). These gentle giants are found in tropical and warm temperate waters worldwide, often inhabiting areas with high productivity, such as coral reefs, seamounts, and coastal waters.
Common Names
Whale sharks are commonly known as whale sharks or Rhincodon typus.
Characteristics
Whale sharks possess distinctive physical characteristics that set them apart from other fish species:
- Size: They can reach enormous sizes, with the largest recorded individual measuring over 40 feet (12 meters) long.
- Filter Feeding: Whale sharks are filter feeders, meaning they strain plankton, krill, and small fish from the water through their large mouths.
- Gill Slits: They have five prominent gill slits on each side of their heads.
- Dorsal Fins: Two dorsal fins, the first being larger than the second.
- Coloration: Their bodies are typically gray or bluish-gray, covered in white spots and stripes.
- Large Mouth: Their mouth is exceptionally wide, stretching nearly the entire width of their head.
Environments
Whale sharks are found in warm, tropical waters, primarily in the open ocean and coastal areas. They are often observed near coral reefs, seamounts, and areas with high productivity.
