![]() Use different pencil strokes to create the texture of the shark’s scales. Step 7: Add Shading and TextureĪdd shading and texture to the shark’s skin to give it a more realistic look. Step 6: Refine the SketchĬlean up the sketch by erasing any unnecessary lines and smoothing out the curves. Next, add some shapes for the shark’s teeth and the scales on its body. Step 5: Add More Details to the Body and FinsĪdd more details to the body by sketching some lines to indicate the muscles. The gill slits are located on the side of the shark’s head. Step 4: Add Details to the Shark HeadĪdd a small circle for the eye, a half-circle for the mouth, and a slightly curved line for the gills. The dorsal fin is located on the back of the shark, while the ventral fin is on the belly. Step 3: Sketch the Upper and Lower Finsĭraw two more triangular shapes for the dorsal and ventral fins. The pectoral fins are located on each side of the shark’s body, just behind the gills. Step 2: Sketch the Head and the FinsĪdd a circle for the head and two triangular shapes for the pectoral fins. Make sure the triangle points towards the direction the shark is swimming. Draw an oval for the body and a triangle for the tail. Start by drawing the basic shape of the shark. Materials Neededīefore you start drawing, gather your materials. Here’s a step-by-step guide to help you draw a realistic shark. As we continue to face increasing anthropogenic stressors, novel approaches such as this provide valuable tools to mitigate the damage caused by unsustainable exploitation.Drawing a shark may seem daunting, but it can be easily achieved with a few basic shapes and some attention to detail. It offers a glimpse of hope for the future of sharks and rays, which are vital components of marine ecosystems and warrant our urgent attention to ensure their survival. ![]() This innovative approach has the potential to revolutionize how we monitor and protect these species globally. The use of DNA metabarcoding in trade monitoring, particularly for elasmobranchs, marks a significant advancement in conservation efforts. ![]() However, challenges remain, particularly in identifying closely related species and setting operational frameworks for this approach. The unconventional method presents several advantages over traditional eDNA testing, such as reduced labor requirements and costs, enhanced detection of species not visible during standard inspections, and the ability to identify cryptic and rare species. These findings emphasize the importance of heightened monitoring. Moreover, it has identified a significant proportion of CITES-listed species, indicating that these species continue to be traded despite conservation efforts. Dust samples have detected a greater number of species compared to individual tissue samples, highlighting the potential of this innovative approach. "Shark-dust" metabarcoding has unveiled a more comprehensive picture of the shark and ray species being traded. The study has yielded remarkable findings. This combination of factors necessitates innovative and effective mechanisms for monitoring elasmobranch populations and ensuring their sustainable management. While some elasmobranch fisheries can be managed sustainably, many succumb to overexploitation due to the market demand for their valuable products. Elasmobranchs exhibit conservative life histories, characterized by slow reproductive rates and increased vulnerability to overfishing. ![]() It’s even worse for those who call coral reefs home nearly two-thirds (59%) of the 134 coral-reef associated shark and ray species are threatened with extinction. The IUCN has found that overfishing drives over one-third of all sharks and rays toward a global extinction crisis. One of the most concerning examples of this ecological crisis is the severe decline in populations of sharks and rays, collectively known as "elasmobranchs." Anthropogenic stressors, such as overfishing driven by market demand for high-value products like fins, liver oil, and gill plates, have put elasmobranchs on the brink of collapse. In recent years, the global environment has been grappling with the devastating consequences of anthropogenic stressors, resulting in the dramatic depletion of numerous species and habitats across the planet. ![]()
