Ancient Anchovies

Scientists have found a fossil which shows ‘sabre-toothed’ anchovies in the sea millions of years ago – with enormous, sharp teeth.

Anchovies nowadays are very tiny fish, about half the length of your little finger.  You often find anchovies on the top of a pizza! Lots of people don’t like them as they have a very strong flavour, but anchovies are important in the oceans food chains as they feed on plankton, and then get eaten by bigger fish.

 

But millions of years ago (about 55 million years to be precise) it seems these anchovies were huge predators.

A Reviewer for Book 1 – Eye of the Turtle

This book is a thrilling adventure about Lucy and her friends Jack and Solomon. It’s an exciting book and it is also a great idea to add in the pictures and information about the sea creatures that are mentioned in the book in the back of it. If you like books with cliff hangers everywhere look no further. I really enjoyed this book and I can’t wait to read the next one in the series.

Viruses in the Ocean

Tens of millions of different kinds of viruses might be lurking in the oceans.  They are incredible small (as many as 10 million viruses can be found in a millilitre of water)

 

This may not be as dangerous as it sounds as not every virus infects every living thing, and some animals actually prey on viruses (which removes virus from the environment).

It seems that viruses are most common in marine environments, but very little is known about which creatures eat them. Some research has been done and it seems that sponges are the champions at eating viruses as in a scientific test they ate 98% of the viruses available in 24 hours. In second place were crabs, eating 90% in 24 hours. Thank you sponges and crabs for keeping the viruses out of our way.

Scientists find an animal that doesn’t need oxygen to survive

Every living thing on Earth has a microscopic structure in all cells call mitochondria which uses oxygen to produce energy. There has only been one known exception to this ‘rule’ up to now – some tiny creatures living in the oxygen depleted waters at the very bottom of the dark black oceans have mitchondria but use a replacement for oxygen called hydrogen sulphate.

But now scientists have found a strange parasite inside a jellyfish. Parasites are not normally loved, but science researchers now find them fascinating as they found this parasite doesn’t have a gene to make a mitochondria. So how can this parasite exist. Researchers are working on this now!
