The shark was first spotted in Mexico by researcher Mauricio Hoyos Padilla. Deep Blue was featured on the Discovery Channel's Shark Week.
This list includes long-lived organisms that are currently still alive as well as those that are dead. Determining the length of an organism's natural lifespan is complicated by many problems of definition and interpretation, as well as by practical difficulties in reliably measuring age, particularly for extremely old organisms and for those ...
The female shark measured about 13 feet long and was just over 100 years old, Estévez-Barcia said in the release. Based on its missing tail, the animal was likely killed by fishermen.
It contains two extant and four extinct species. The most widely known species still surviving is the frilled shark (Chlamydoselachus anguineus). It is known as a living fossil, along with Chlamydoselachus africana, also known as the southern African frilled shark, which is only found along coastal areas of South Africa. The only two extant ...
The otodontid sharks have been considered to have been ectotherms, so on that basis megalodon would have been ectothermic. However, the largest contemporary ectothermic sharks, such as the whale shark, are filter feeders, while lamnids are regional endotherms, implying some metabolic correlations with a predatory lifestyle.
The frilled shark eats a diet of cephalopods, Nudibranchs, smaller sharks, and bony fish; [2] 60 percent of the diet is composed of squid varieties, such as the Chiroteuthis, the Histioteuthis, and the Onychoteuthis, the Sthenoteuthis and the Todarodes; [17] and other sharks, as indicated by the stomach contents of a 1.6 m (5.2 ft)–long ...
The shark is believed to be an ancestor of the great white shark. It is now extinct, but its teeth once spanned up to 8.9 cm (3.5 inches) in length, while adults could grow to near seven meters in ...
