Only one female with a embryo has even been recorded and she was said to gave given birth to five live young and one still born. <ref name=flmnh/> They ranged in length from 1.5 thru 2 meters or 4.5-6 feet, the thought is the Basking Shark is a ovoviviparous<ref name=flmnh/>. The gestation period is thought to be three years or greater. While it has also been proposed that the Basking Shark uses a method of embryonic nutrition known as oviphagy <ref name=flmnh/>. This is when the embryo feeds on other unfertilized eggs or other embryos within the uterus<ref name=flmnh/>. | ||
The female is thought to reach sexual maturity between the ages of 12 and 16 years of age<ref name=flmnh/>. While the male has been paired intromittant organs called claspers. These are located on the inner margin of their pelvic fins <ref name=sharkbio> Aiden, Martin [http://www.elasmo-research.org/education/shark_profiles/cetorhinus.htm] "Biology of the Basking Shark" Web January 17, 2017 (accessed)</ref>. The gestational period is believe to be the longest in any vertebrate lasting as long as 3.5 years <ref name=sharkbio/>. Basking sharks babies are born at an astounding 5 feet in length. This makes them even longer than some full grown adult sharks <ref name=sharlbio/>. | |||
