Evolution in its purest form.
Evolution has been a debate for many years, and one example that has been used to back up the theory aside from the comparisons of humans and monkeys, is the frogfish.
These fish don’t just swim, they propel themselves through water using their fins and they can walk on the ocean floor, using their legs. That’s right legs! Frogfish are usually brightly coloured, allowing them to be camouflage against the reefs in their habitats and the species are said to change colour throughout their life-cycle. This is used for both protection against predators and for catching prey. They mimic their surroundings by making themselves look like other living creatures such as coral, sea urchins and sponges. Their legs which are not attached to their abdomen, are stretched out and pointed downward. Despite having two choices of movement, they move very slowly through the water but they make up for this with their unbelievably fast bite.
They use their camouflage ability to their advantage and sit very still in order to blend in. They then lure in their prey using an appendage which is attached to their dorsal fin, so that their victims mistake it for food and then they strike. Their bite has been described as being lightning bolt fast, which is down to their method of catching prey known as ‘gape and suck’. The reason behind this title is because they drop their jaws (gape) at a .22 speed which creates pressure, causing the water and everything else around the mouth to rush in and then they suck. Having no teeth, means that they have to swallow their prey whole. As a result of this they can only eat small fish; any fish caught, that are larger than they are end up having to be released.
Frogfish can be found all over the world, and it is said that there are a number of different species known to man. Discoveries of new types of frogfish seem to be happening more frequently with a diver finding one that had hair in 2015 and another being found washed up on a beach in New Zealand this year. The new discovery has been described as being a possible member of the frogfish family but is yet to be confirmed by experts at the The Museum of New Zealand. This fish differs from other frogfish as it is black rather than brightly coloured and it has been said to resemble a bird which is an unusual comparison for a frogfish. The discovery follows a number of unusual findings in the Australian seas including a two mouthed fish and a rare prehistoric shark which was caught by a fishermen.
The ocean is said to be 95% unexplored, so it doesn’t come as too much of a surprise that new species are being discovered. There is still a lot to learn about life in the ocean and about the ocean itself; with patience and respect, it can be explored further and more discoveries can be made.
