Humpback Whale

Megaptera novaeangliae
Distribution map of the Central American humpback whale population.

Humpback whales are the most common baleen whale species that we see during the winter season, between November and April each year. The whales we see in Huatulco are individuals believed to be members of the Central American population that is listed as endangered.
Humpback whale populations are geographically distinct and scientifically identified as DIPS or Demographically Independent Population Segments. The Central American DIPS spends the summer months feeding in California and winters in southern Mexico and Central America. Along these tropical shorelines, whales concentrate on mating and giving birth to their young.

Humpback Whales

Humpback whales can be found in most of the world’s oceans and seas. They migrate annually between summer feeding grounds in temperate seas to winter breeding grounds in tropical seas.
All have dark gray to black dorsal coloration with varying degrees of white along the ventral and lateral sides. Its body is robust with long pectoral fins and a wide caudal fin. Its head is broad with raised bumps called tubercles. The mouth is lined with 270 to 400 baleen plates and the throat has 14 to 35 expandable folds of skin that aid in their lunge feeding techniques.
Humpback whales reach 15 meters in length, can weigh more than 40,000 kilograms, and are believed to live for more than 50 years. A humpback whale can eat between 2,500 and 5,000 kilograms of krill and fish in a single day.
Humpback whales have recently been recognized as a major contributor to the seeding of the ocean ecosystem and, in particular, to the increase in phytoplankton levels in the oceans. This phytoplankton provides 50-80% of the oxygen we breathe.

Humpback whale conservation begins with research and responsible whale watching methods.

Humpback Whale Conservation

The Central American DIPS is classified as under threat of extinction. Its population has grown 1.6% in recent years, while the Mexican DIPS (which winters along Baja California, the Sea of Cortez, and central mainland Mexico) averaged 6.8 population growth. %. % during the same period.
Humpback whales are susceptible to; entanglements, environmental degradation, ship collisions and noise pollution.
Our sustainability goals include determining the population and site fidelity of humpback whales along our coast.
We are connected to the whale entanglement response network. We follow Mexican whale watching regulations and use the most modern engines to limit noise pollution.
