Jaws: the revenge. A great white shark kills the son of a grieving widow Ellen Brody. In mourning, the family goes to the Bahamas to visit her other son. Unbeknownst to them, however, the shark has learnt who they are and follows the family... But can sharks actually learn? The short answer: yes they can!… Continue reading Can sharks learn?
Elasmobranchs are among the most endangered vertebrates, with around 25% of species now threatened with extinction. However, effective conservation is being hindered by taxonomic confusion; the high levels of morphological similarities among living organisms mean it is difficult to classify elasmobranchs into accurate species groupings. DNA sequencing technologies have even identified 'cryptic' species within this… Continue reading Species new to science
Above: Juvenile Blacktip reef shark (Carcharhinus melanopterus). IUCN red list: Near Threatened. The growing concern over the decline of elasmobranch (sharks, rays and skates) populations has led to increasing effort to conserve nursery areas, which are thought to be critical for population sustainability. Science is helping us to discover nursery regions, but how effective is protecting… Continue reading Protecting the next generation of sharks- is it enough?
Since I was 6 I wanted to become a marine biologist. From computer coding to field-work and policy-making, there are so many aspects to this career and every step of the way I have absolutely loved it. So, in this competitive field, how can you succeed? Here is my advice... 1. Get the right qualifications.… Continue reading How to become a Marine Biologist: my top 5 tips!
We know more about space than we do the deep sea. We are only just discovering and learning about deep sea elasmobranchs. However, they face growing threats from climate change and overfishing; these anthropogenic (man-made) impacts highlight the need for a better understanding of how we can conserve deep-sea communities. When you think of Elasmobranchs,… Continue reading Shining the light on threats to life in the dark
Concern is growing over the conservation status of elasmobranch populations. An estimated 25% of species are thought to be threatened with extinction worldwide, due to increasing threats from direct overfishing, being caught as accidental bycatch and habitat degradation. Despite this concern, managing and conserving elasmobranch populations has proven to be a difficult task- but why? Elasmobranchs (sharks,… Continue reading Why is conserving elasmobranchs so difficult?
The whale shark (Rhincodon typus) is the world's largest fish, growing up to 65 feet and weighing around 75,000 pounds! Despite this huge size, they prey on tiny organisms. Whale sharks are known as filter feeders; they feed by ingesting huge amounts of water, and filtering out plankton, small crustaceans and fish, which get trapped in… Continue reading An over-whale-ming animal
