Seasons by month
Marine life you can see in May
About this list
This page reads the season tables on the animal pages from the month's side: where to go in May and what you can see there. 53 animal and place pairs are in season in May: 16 animals in 22 places. Hammerhead sharks, manta rays, dolphins, whale sharks and sperm whales, among others, are in season this month. 4 of them are seasons stated by a tourism board, research body or local operator; the rest are months where the program seasons of two or more operators overlap. Hammerhead sharks in Ecuador, manta rays in Khao Lak & the Similan Islands, Thailand and manta rays in the Maldives, among others, single out May. 27 pairs that do not depend on the month are listed separately below: resident populations, or operators that list year-round operation. The months are what the source says, not a sighting guarantee. Even within the same month it depends on the sea and migration routes, so ask the operator about recent conditions before you book.

Frequently asked questions
What marine life can you see in May?
53 pairs are in season in May, including hammerhead sharks in Ecuador (Dec–May), manta rays in Khao Lak & the Similan Islands, Thailand (Oct–May), dolphins in Izu Islands, Japan (Apr–Nov), manta rays in Raja Ampat, Indonesia (Nov–May), manta rays in the Maldives (May–Nov) and whale sharks in the Philippines (Nov–May). Select an animal to see its season table by country, or a place to see its operators.
Who decides these months?
Two kinds of evidence. 4 pairs use a season stated by a tourism board, research body or local operator, with a source link and check date on each page. The rest are months where the program seasons of two or more operators overlap, marked as based on operator listings.
Why are animals that do not depend on the month listed separately?
Resident populations such as dugongs, sea turtles, sharks and manta rays can be seen in May too, but nothing about this month makes them special, so they come after the animals in season.
If I go in May, will I definitely see them?
That is not guaranteed. A season is the period its source states, and actual sightings vary each year with the sea, water temperature and migration. Ask the operator about recent sightings before you book.
