Os tubarões têm enfrentado momentos difíceis desde a década de 1970, com a sobrepesca, a perda de habitat e o crescente comércio de barbatanas reduzindo suas populações. O filme “Tubarão” não ajudou.

Sharks have had a tough time since the 1970s, when overfishing, habitat loss and a growing trade in their fins began to cut their populations. ‘Jaws’ didn’t help.
Film ‘Jaws’ berhasil mendorong banyak riset tentang hiu. Mitos hiu sebagai hewan bengis sudah seharusnya ditinggalkan.
Um especialista em tubarões, cuja curiosidade sobre esses peixes fascinantes foi despertada pelo filme, explica algumas de suas características exclusivas. Muitas descobertas foram feitas nas décadas seguintes a “Tubarão”.
A shark expert whose own curiosity about these fascinating fish was sparked by the movie explains some of their unique features. Many discoveries came in the decades after ‘Jaws.’
Como os tubarões-martelo dão à luz filhotes vivos, estudar seu desenvolvimento embrionário é muito mais complicado do que colher alguns ovos e observá-los se desenvolver em tempo real
Because hammerhead sharks give birth to live young, studying their embryonic development is much more complicated than harvesting some eggs and watching them develop in real time.
The first teeth may have evolved from combination of scales and tastebuds.
Understanding the genetic origins of sharks’ teeth could one day lead to new treatments for humans.
