Blue glaucus can grow up to 1.2 inches (3 cm) long. The bonnethead shark or shovelhead (Sphyrna tiburo) is a small member of the hammerhead shark genus Sphyrna, and part of the family Sphyrnidae.It is an abundant species on the American littoral, is the only shark species known to display sexual dimorphism in the morphology of the head, and is the only shark species known to be omnivorous. behavioral Adaptations. dorsal fin- helps it move around in the ocean. The planet Earth can be a difficult place to survive. Although the shark is a capable predator in many waters, sharks mainly change their environment when in search of food. The Blue Shark is a species of shark found almost everywhere in the world and is the most widely distributed shark species. Some of the most common predators of blue sharks are killer whales, tiger sharks, great white sharks, and of course humans. As mentioned before, one of the Blue shark facts is that the Blue shark prefers a habitat of deep, cool waters, making it an epipelagic species. ... Adaptations. They are survivors! The shark has wide- set eyes to cover more area when hunting. 2. These sharks are the only shark that travel in packs (or schools) to catch prey. SHARKS ADAPTATIONS.

Some others were similar to eels; their faces featured noses that were round rather than pointed. 3. After millions of years of adaptations, more than 500 species of sharks swim the planet's oceans today, and sharks … Sharp sense of smell- helps find prey. Limiting factor on population Its genome is 4.63 Gbp, over half of which is represented by repeat sequences, including a large proportion of transposable elements. Averaging around 3.1 m (10 ft) and preferring cooler waters, the blue shark migrates long distances, such as from New England to South America.It is listed as Near Threatened by the IUCN. Blue glaucuses can swallow air … A Tiger Shark swims over coral reef in Fuvahmulah, Maldives. Shark Adaptations.
