and why is the last one called 'hammerhead'?
It is named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a cephalofoil.

please tell me more about jaekelopterus It is a genus of predatory eurypterid, a group of extinct aquatic arthropods. is their species still alive? UNANSWERABLE where can they be found? It lived in non-marine aquatic environments. you mentioned that these were predators, what more can you tell me about them as predators? Fully grown "Jaekelopterus" would have been apex predators in their environments and likely preyed upon smaller arthropods (including resorting to cannibalism) and early vertebrates. you mean they ate each other, but what would be the benefit? UNANSWERABLE what harm can come by eating each other? It has been shown in some studies that the risk of encountering an infected victim increases when there is a higher cannibalism rate. do you know any other species that eats each other? Aquatic ecosystems please tell me more about this Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. can you please name a few of these organisms Whales, sharks, and tuna live etc can you please describe the first one to me UNANSWERABLE can you please describe the second one to me They are characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. what are their different types? Tiger shark, blue shark, great white shark, mako shark, thresher shark, and hammerhead shark what more can you tell me about the first one? It is a large macropredator, capable of attaining a length over. is there any reason why it is referred to as 'tiger'? Its name derives from the dark stripes down its body, which resemble a tiger's pattern. do you know why the second one is named as 'blue'? The top of the body is deep blue, lighter on the sides, and the underside is white. where are they found? They are found off the coasts of every continent, except Antarctica. Its greatest Pacific concentrations occur between 20° and 50° North. which other shark did you mention before? Great white shark, mako shark, thresher shark, and hammerhead shark yes, thanks for reminding me, how big does the first one grow to? It is notable for its size, with larger female individuals growing to in length and in weight at maturity. However, most are smaller; males measure , and females measure on average.

Hammerhead shark [SEP] Introduction
The hammerhead sharks are a group of sharks that form the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a cephalofoil. Most hammerhead species are placed in the genus "Sphyrna", while the winghead shark is placed in its own genus, "Eusphyra". Many, but not necessarily mutually exclusive, functions have been postulated for the cephalofoil, including sensory reception, manoeuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and continental shelves. Unlike most sharks, some hammerhead species usually swim in schools during the day, becoming solitary hunters at night.
