Every spring, a large number of whale sharks flock to Gladden Spit Marine Reserve, about 30 mi (48 km) off the coast of the Placencia peninsula. A unique spawning and breeding area for over 20 fish species attracts whale sharks because they feed on fish eggs. Whale sharks are especially abundant in Belize during March, April, May, and June. April and May tend to be the best months.

The body is dark grey with a white belly as well as spots and stripes unique to each individual. The whale shark has two dorsal fins and a pair of pectoral fins.
