It’s #FunFactFriday! #DYK that Harbour Porpoises have Megatestes?! That’s right, male Harbour Porpoise testes can swell to 4% of their body mass. The idea is to produce so much sperm that other males’ competing sperm is flooded out or just outnumbered in the female’s reproductive tract. If humans employed the same mating strategy, human testes would be 1.25 kg each (compared to the 17-27 g they are now). That’s at least 46 x bigger. #whaletales #porpoise #didyouknow #trivia #fff #porpoiseareawesome #harbourporpoise #porpoiseofinstagram #getonaboat #exploreBC #salishsea#porpoisewatching #howesound #yvr⠀ https://www.instagram.com/p/Bx2i2LxBBOT/?igshid=3s3lsmoh2eha
Today is International Day of the Baltic Sea Harbour Porpoise. What may seem like a very specific holiday is incredibly important. There are only approximately 500 porpoises left in the Baltic Sea and this species is critically endangered. They are threatened by fishing nets, like all porpoises, and while some protection has happened more is needed. Learn more about what you can do at @Porpoisedotorg

It’s #FunFactFriday! #DYK that Dall’s Porpoises are one of the most commonly misidentified animals off of the coast of BC? They are frequently thought to be “baby” Killer Whales, even the largest of these cetaceans (2-2.4 m long) is still smaller than a newborn orca (2.6 m)!⠀

Seeing a living, breathing spectacled porpoise is a bit like catching a glimpse of a unicorn. They are one of the most poorly known marine mammals in the world. There are only a handful of live sightings of this species and carcasses are found perhaps only once or twice a year. Live strandings are so rare it has only been documented a few times.
His swimming patterns were not affected and he was able to swim freely in the tank by himself. Staff gave the porpoise round-the-clock care, tube feeding him and providing medical treatment.

Unfortunately, the male porpoise died on January 30th, four days after his rescue. He had ulcers in his stomach, liver problems, a large parasite load, and was severely underweight. His odds of survival were not great to begin with. However, the data collected by the Mundo Marino Foundation on this animal will go far to further scientists’ knowledge of this enigmatic and mysterious species.
It’s #FunFactFriday! What do you know about the Spectacled Porpoise? Scientists actually know very little about this species and more research is needed! Some species of porpoise, like the Spectacled Porpoise, are classified as “data deficient”, with very incomplete information regarding their reproductive strategies, numbers, migration, and distribution.⠀
