Their seemingly useless teeth may play a role before birth in helping them feed on the mother's unfertilized ova (a behaviour known as oophagy).
The gestation period to birth young is about one year. The age of maturity is thought to be between the ages of six and 13 and at a length of 4.6–6 m (15–20 ft).

In parts of western Canada in the 1950's, it was considered a nuisance to fishermen; an eradication program to eliminate basking sharks involved fitting a Fisheries vessel with a sharpened ram on the bow to impale and kill basking sharks. Gestation is thought to span over a year (perhaps two to three years), with a small, though unknown, number of young born fully developed at 1.5–2 m (4 ft 11 in–6 ft 7 in).
