The two largest sharks are the whale shark (Rhincodon typus) and the basking shark (Cetorhinus maximus).
- Whale Shark: The whale shark holds the title for being the largest fish species in the world. It can reach lengths of up to 40 feet or more, although average adult individuals are usually around 32 feet long. They can weigh several tons. Despite their enormous size, whale sharks are filter feeders and primarily consume plankton and small fish. They have a broad mouth and distinctive patterning of spots and stripes on their body.
- Basking Shark: The basking shark is the second-largest shark species and can grow to impressive lengths. It typically ranges from 20 to 26 feet in length, although some individuals have been recorded measuring up to 40 feet. Basking sharks are known for their massive, gaping mouths, which they use to filter feed on plankton and other small organisms. They have a unique appearance, with a large dorsal fin and a grayish-brown body.
Both the whale shark and the basking shark are filter-feeding sharks and are harmless to humans. They are gentle giants of the ocean and play an important role in marine ecosystems.
