  1. 1. Hammerhead shark By: Samuel
  2. 2. reproduction Hammerhead Sharks are viviparous, meaning they give live birth. Females usually give birth to 12 to 15 pups at a time, but the Great hammerhead shark gives birth to around 20 to 40 pups at a time. Once they are born, baby Hammerhead sharks come together in groups and swim towards warmer waters. They stay together in groups until they are older and big enough to live on their own. Hammerhead shark live for around 20 to 30 years.
  3. 3. information The hammerhead sharks are a group  of sharks in  the  family Sphyrnidae,  so  named  for  the  unusual  and  distinctive  structure  of  their  heads,  which  are  flattened  and  laterally  extended  into  a  "hammer".  Many  functions  have  been  proposed  for  the  “hammer”,  including  sensory  reception,  maneuvering,  and  prey  manipulation.
  4. 4. description The known species range from 0.9 to 6 m in length  and weigh from 3 to 580 kg. They are usually light  gray and have a greenish tint. Their bellies are  white which allows them to blend into the ocean  when viewed from the bottom and sneak up on  their prey. Their heads have lateral projections  which give them a hammer-like shape. They swim  to warmer climates in groups of 500 sharks.
