The ancient 'missing link' toothless whale that sucked squid into its mouth

A prehistoric 15-foot-long (4.5 meters) whale that sucked prey into its mouth represents a key missing puzzle piece concerning the evolution of today's huge filter-feeding whales, scientists have revealed.

The researchers described fossils unearthed of a whale named Maiabalaena nesbittae that lived 33 million years ago, according to Daily Mail.

They possessed neither teeth nor baleen, the material that modern filter-feeding whales use to strain large amounts of tiny prey out of the water for food. 

Dogs are 'no more intelligent' than cats say experts

It may seem from a dog's friendly demeanour and ability to perform tricks that they are smarter than most animals but a new study suggests this is not the case. 

Psychologists from Exeter and Canterbury University examined the cognitive abilities of 'man's best friend' when compared with other animals - including cats.

Experts concluded that canines do not possess particularly higher intelligence than their feline rivals, as well as a number of other creatures, according to Daily Mail.  

Researchers used data on observations of the behaviour of dogs, cats, wolves and chimpanzees to see if pooches possessed any specific special skills.

Predators drive Nemo's relationship with an unlikely friend

Predators have been identified as the shaping force behind mutually beneficial relationships between species such as clownfish and anemones, according to Science Daily.

The finding results from a University of Queensland and Deakin University-led study.

Dr William Feeney said the research aimed to understand the origin of such relationships, known as interspecies mutualisms, which are extremely common in nature.

"Clownfish -- like Nemo from Finding Nemo -- and anemones are a great example of this type of relationship," he said.

"Clownfish live in and around anemones, helping drive off the anemone's predators and providing it with food, while in exchange the anemone provides protection with its stinging tentacles.

A three and a half tonne UNICORN roamed the Earth with prehistoric humans 39,000 years ago before being wiped out by the Ice Age

Ancient humans lived alongside giant 3.5 tonne woolly rhinos known as 'Siberian Unicorns'.

The beast had an enormous single horn adorning its large head and scientists now believe the species lived alongside Homo sapiens and Neanderthals. 

Expert analysis has found the rhino survived until around 39,000 years ago - far exceeding the previous estimates of extinction which varied between 200,000 and 100,000 years ago, according to Daily Mail. 

The large herbivore is thought to have gone extinct as a result of sudden climate change which decimated their small populations. 

Whales change their tune regularly in order to keep it simple for their pod to remember

Every few years the songs performed by the humpback creatures are ditched in favour of more basic alternatives, according to Daily Mail.

Experts say this is the mammal's version of a re-set button and ensures that the anthemic melodies remain easy for their community to remember.

Scientists from the University of Queensland and St. Andrews University, Scotland, call this 'a cultural revolution' after studying the species for 13 years.

Focusing on 95 male humpbacks, the research revealed that gradual song changes naturally stem from individual creatures but are quickly learned by the rest of the group.
