Dolphins are as dumb as worms, claims new study

Published

on

Dolphins may be more stupid than goldfish, chickens and even mealworms, new research suggests.

Scientists say the idea that the animals have equal or superior intelligence to humans and apes is unfounded, and that many of the ‘skills’ attributed to them – such as the ability to use a tools and communicate with a complex ‘language’ – are either shared with other animals or are simply urban myths.

In a new paper, neuroethologist Paul Manger of the University of Witwatersrand in South Africa says behavioral studies involving dolphins are flawed and therefore not very informative.

‘We put them on a pedestal for no reason and projected a lot of our desires and wishes on them,’ said Manger. ‘The idea of the exceptionally intelligent dolphin is a myth.’

Whereas goldfish placed in a bowl try to jump out to freedom, dolphins rarely try to escape when they are caught in nets.

While zoologists have observed that dolphins can distinguish between the concepts ‘many’ and ‘few’, he suggests the same ability has also been demonstrated in yellow mealworms.

Manger said evidence that dolphins have learned sophisticated ‘tool use’ is ‘flimsy’, based as it is on the fact that some bottlenose dolphins on Australia’s west coast have learned to hold sponges in their snouts to help them find food on the ocean floor.

‘Exactly what the dolphins do with the sponges remains unknown,’ he said.

While researchers have been able to teach bottle-nosed dolphins to recognise an ‘alphabet’ of as many as 40 symbols, Manger pointed out that African grey parrots and California sea lions have also managed the same feat.

And while much has been made of the dolphin’s ability to identify itself with a ‘signature whistle’, experts now say that this is not a complex language, and say it is no more unusual than the tail-wagging dances of bees or ‘signature’ accoustic signals made by other marine animals.

A new book by Justin Gregg, a zoologist with the US-based Dolphin Communication Project, is also seeking to bring to light this research that could strip the animal of its title of brainbox of the seas.

‘It’s probably not the case that dolphins have their own language, which is as complex as human language,’ said Gregg, an expert in animal communication.

Dive with a Purpose: Shark Guardian’s Expedition Galapagos

Published

on

Shark Guardian has just unveiled their largest and most exciting expedition yet: a seven-night, eight-day adventure in August 2026 aboard the Galaxy Diver II, a state-of-the-art
vessel specifically designed for divers exploring the enchanting waters of the Galapagos
Islands. This is a once in a lifetime opportunity to engage deeply with marine
conservation in one of the world’s most revered diving destinations.

Shark Guardian is a UK registered charity dedicated to protecting sharks and marine
ecosystems worldwide. Founded by marine biologists and conservationists, Brendon
Sing and Liz Ward-Sing, Shark Guardian leads educational programs, research projects,
campaigns and expeditions aimed at fostering a better understanding and respect for
marine life. Their work spans several continents and focuses on direct action,
education, and advocacy.

Shark Guardian’s ethos revolves around the concept of “diving with a purpose.” This
philosophy underscores the importance of not just experiencing the wonders of the
underwater world but actively learning and contributing to its preservation. Participants
in Shark Guardian expeditions engage in citizen science projects, which involve
collecting data that supports ongoing research and conservation efforts. These
activities empower divers to make a tangible difference, turning each dive into an act of
conservation.

One of the newer additions to the Galapagos diving scene, the Galaxy Diver II, is
specifically tailored for divers. Its design prioritises comfort, safety, and environmental
responsibility. The vessel boasts modern amenities, spacious dive decks, and the latest
navigational technology, ensuring that every dive is not only memorable but also has
minimal environmental impact.

A highlight of this expedition is the opportunity to dive at Wolf and Darwin islands,
renowned for their vibrant, untouched marine ecosystems and as a haven for large
pelagic species. These islands are famous for their schools of hammerhead sharks,
whale sharks, and manta rays, offering spectacular diving that attracts enthusiasts from
around the globe.

Shark Guardian have developed this trip to ensure a hassle-free experience. The
expedition package also includes internal flights from Quito, Ecuador, to the Galapagos,
plus accommodation in Quito before and after the trip. This allows divers to relax and
enjoy the experience without worrying about logistics.

Participants will join a diverse group of passionate divers and conservationists. This trip
offers a unique opportunity to network with like-minded individuals who are eager to
learn about and contribute to marine conservation. It’s a chance to share experiences,
knowledge, and a commitment to protecting the marine world.
