Deep Sea Skates – New Species Discovered!

According to a scientific paper published on 13th July 2016 – a new species of deep-water legskate was recently described by scientists Weigmann and Stehmann.

Sharkwater:Extinction – A Mission To Save Sharks

A few years back, Sharktrooth watched a film called Sharkwater. It was one man’s incredible journey beneath the surface of the finning industry into some deep and disturbing areas.

Hammerheads & Whale Sharks Becoming Extinct

The IUCN (International Union for the Conservation of Nature) has just updated its Red List of Threatened Species.

Females instead have an opening called a ‘cloaca’. When you watch shark week do you see more males or females? The best time to see this is looking…

Why Sharks Don’t Go To The Dentist

Shark teeth are covered in fluoride which makes them cavity-resistant. A study published in the Journal of Structural Biology in 2012 discovered that the enamel on sharks teeth is actually made up of a chemical called fluoroapatite. Fluoroapatite is resistant to acid produced by bacteria so this means that shark’s teeth don’t decay. Also, most…

New GuitarFish Discovered?

Scientists Peter R. Last, Bernard Séret and Gavin J.P. Naylor are proposing a revised classification of the guitarfish based on materials collected from the South China Seas. Taxonomy and classification is how we understand different animals that are closely related and taxonomy is the science of defining groups of biological organisms (animals) on the basis…

World Oceans Day

One of the reasons that certain people (Sharktrooth included) are so passionate about saving sharks and conserving the oceans is that we need the oceans more than the oceans need us. The oceans are amazing. Not only are they the life-support system for the planet, but if we don’t take proper care of them, they…
