Scientists from the University of South Wales in Australia studied several species of blenny fish - often referred to as blennies - in Rarotonga, which is one of the Cook Islands. Scientists believe ancient creatures used the powerful tails they relied on as fish to crawl across the mud and sand as they made the move onto land 400 millions years ago.Ancient animals similar to blenny fish would have used modified fins to move around on flat surfaces.Based on fossil records research suggests fish tails may have helped supplement the work of fins, especially on sloping granular surfaces such as beaches and mudflats. Blenny fish in the Cook Islands are in the process of colonising land and are using their fins to jump around rocks, according to experts. But the fact they developed this unusual ability – one not commonly associated with a fish – implies they might never be able to go back to the water further down the evolutionary line.

The rockskipper (Istiblennius zebra) is a small Hawaiian blenny representative of several that live along shores and can hop about on land. They lay their eggs in rocky shelters and eat algae and bacteria from rocks - just like they did underwater.
They still use their gills to breathe but their tail fins have become so strong they use them to jump around. but it is $250 cheaper and still get most of the other cutting-edge features found on the more expensive model.AI seems to permeate every part of its software, from the ability to answer calls for you to being able to almost perfectly predict your morning commute.Apple's new iPhone XS and XS Max go on sale on Friday - and the biggest handset Apple has ever made is also its best (and possibly unsurprisingly, its most expensive).Israeli beauty-tech firm Pollogen has launched its Geneo Personal device, which stimulates oxygen from beneath the skin's surface to give you a clearer, fresher face within minutes.Rather than cram in a plethora of new features, Apple's latest update is about boosting stability, with improvements in everything from FaceID and battery life.It's eye-wateringly expensive at $2,999, but Naim's Uniti Atom is a revelation, an integrated amplifier than makes it easy to stream music at a quality you've probably never heard before.Naim's incredible Mu-So Qb takes you back to the good old days - where the music captivates and enthralls, rather that simply being something in the background.Peloton's hi-tech bike lets you stream live and on demand rides to your home - and it's one of the best examples of fitness technology out there - at a price.It might not be a name familiar to the US market, but Naim is a legendary British brand hoping to make a splash with the American launch of its $1499 Mu:So speaker. Around 33 families of fish have relocated onto land in the past 400 million years - a move which once gave birth to modern-day humans. But as the tide rises, these small fish do something extraordinary and literally get out of the water and climb onto dry land, according to Experts believe they do this to avoid larger fish such as flounders and lionfish who prey on them.To test the hypothesis, scientists made plasticine models of blenny fish and submerged them in the sea. Kirk's blennies are found around the Indian Ocean, inhabit waters near the shore and often spend time out of the water.A diverse diet and flexible behaviour allowed a type of Some species of blenny – which typically has a slim and almost eel-like body – made their dramatic transition out of the water millions of years ago.This has led to noticeable physical changes in their evolution, such as teeth suited to scraping rocks for morsels and mottled skin to help blend in with rocks and hide from predators.Having a broad diet or being behaviourally flexible can help a species move into a new habitat, but once there, this flexibility becomes ‘eroded’ by natural selection.This indicates that highly specialised species are less likely to be able to make further transitions, or cope with abrupt environment changes in their existing habitat.Blennies are a remarkable family of fish with different species occupying strikingly different environments.Some are aquatic, while others spend time in and out of the water in the intertidal zone – an extreme environment with fluctuating water levels and pools that can rapidly change in temperature and oxygen levels.Others still are terrestrial and spend almost their entire lives out of the water in the splash zone and must keep moist in order to breathe through their skin and gills.Despite these challenges, blennies have been incredibly successful in repeatedly making these dramatic transitions.Terrestrial blennies are really agile out of water and likely adapted their body shape to allow them to hop about the rocks freely.As an example, the rockskipper (Istiblennius zebra) is a small Hawaiian blenny representative of several that live along shores and can hop about on land, as can the Pacific leaping blenny (Alticus arnoldorum).
