Every Animal With an Insanely Long Pregnancy

You won't believe how long some animals stay pregnant. We're exploring creatures with insanely extended gestation periods—the alpine salamander stays pregnant for THREE YEARS (and the babies cannibalize their siblings in the womb), African elephants carry for 22 months to build those massive complex brains, and the frilled shark holds the record at 3.5 years because cold deep-sea water slows everything down to a crawl. The walrus does this wild thing where the embryo just floats around for months before implanting so the calf is born at the optimal time of year. Honestly, nature took "slow and steady" to absolutely extreme levels with these species. #animalfacts #pregnancy #elephants #endangeredspecies #wildlifeeducation TIMESTAMPS 00:00 Alpine Salamander 01:20 African Elephant 02:50 Frilled Shark 04:12 Sperm Whale 05:43 Black Rhinoceros 07:22 Velvet Worm 08:40 Bactrian Camel 10:10 Walrus 11:31 Giraffe 12:59 Orca
