Aqui uma compilação de alguns vídeos de tubarões-brancos do cinegrafista marinho Anthony Kobrowsky, da página @seacandymedia.

Estas imagens são ótimas para vermos alguns detalhes específicos dos elasmobrânquios (subclasse de peixes cartilaginosos de que fazem parte os tubarões e as raias), como suas brânquias sem opérculos e a forma como a água passa por elas, as nadadeiras, as camadas de dentições, os cláspers (par de órgãos genitais masculinos), entre outras características.
Infelizmente, também podemos ver algumas características horríveis da espécie humana, quando percebemos feridas causadas por redes em alguns animais e um anzol preso a outro deles.

  • A montage dedicated to my favorite creature on SeaWorld Ancol. Back in 2013, SeaWorld Ancol added Hammerhead Sharks to their collection. There used to be 10 of them back then, but their number diminished as they become too big, so they had to be released. One of them died from diseases unfortunately. Now, only 4 remains (3 on display and 1 on quarantine)

  • Apresento-lhes Cláudia Raia (também atende por Arraia!). Ela faz parte da classe dos Chondrichthyes, popularmente chamados de peixes cartilaginosos, e inserida na subclasse dos Elasmobranchii (a mesma dos primos tubarões). O exemplar foi filmado no aquário de São Paulo. No vídeo podemos perceber as aberturas branquiais e também a boca do animal; os olhos  e também os espiráculos, por onde a água entra para realizar a respiração, encontram-se na parte dorsal.
Animal de modo de vida bentônico, achatado dorsoventralmente para esse estilo de vida e, em sua maioria, dentes adaptados para triturar conchas e exoesqueletos de invertebrados #chondrichthyes #biounipjundiai #elasmobranchii #zoologia #biologia #peixescartilaginosos

  • سپر ماهیان اژدهای خفته دریاها  دم شلاغی این ماهیان غضروفی در برخی گونه ها به دو یا سه برابر طول بدن نیز میرسد. عمده گونه ها در ناحیه دمی مجهز به خار زهرآلودی هستند که می تواند مهاجمین را زمین گیر نمایند.

هیچ جانوری بالقوه مهاجم نیست الا زمانی که حس تهدید را در آنها ایجاد کرده باشیم لذا با طبیعت مهربان باشیم

  • Here’s some animals very close to my heart...sharks! From a very young age me and my brother would gather around the tv for shark week, or if we weren’t doing that we would be watching videos about them on YouTube, or reading books about them, I mean we were obsessed! And why? Who knows, other than that we both had a great respect for such a cool and unique animal. Sharks are members of Class Chondrichthyes, subclass Elasmobranchii. Sharks are classified different from bony fish for their cartilaginous bodies! Their entire body, excluding their teeth and jaws, is made of cartilage! Also, have you ever heard that sharks constantly have to keep moving, but wondered about sharks that don’t move much? I always have, some sharks have spiracles, which are little holes on their heads that allow air to pass over the gills, meaning the sharks with spiracles do not in fact have to constantly move. Sharks have an incredible sensory system as well, with a lateral line of sensory running down their bodies, and something known as the “Ampullae of Lorenzini” on their faces, giving them the ability to detect electromagnetic fields! Overall, a pretty amazing animal, and a top notch predator....but who’s the real predator here? Did you know that HUMANS kill 100 millions sharks annually? Whereas sharks kill 6 people annually. 6 to 100 million. Often times sharks are killed for nothing more than their fins, used in foods and forms of old Chinese medicine, and also for sport. In some cases sharks are caught, have their fins cut off, and then are thrown back into the ocean, left to die. Shark populations are dropping yearly from this kind of harvesting and cruelty! This is a problem that we have to change!! So what can you do? 
1. ALWAYS VOTE, their are bills all over being introduced to protect sharks, be aware, be informed, and VOTE
2. Spread as much awareness about the problem as you can! This matters, sharks are VITAL to our ecosystem, not to mention they are beautiful creatures! Let’s do what we can to help them!

  • Happy World wildlife day 🐠🐙🐡🦐🐬🦞🦀🦈🐋🐠🐳
•
In 2019 this day highlights “Life below water: for people and planet", which aligns with goal 14 of UN Sustainable Development Goals 🌊🌊🌊🌊
•
The ocean contains nearly 200,000 identified species, but actual numbers may be in the millions.
•
As much as 40% of the ocean is now heavily affected by exploitation of marine species as well as other threats such as pollution, loss of coastal habitats and climate change.
•
Let 2019 be the year where the oceans will live instead of drowning! 🙏🏻

  • Holotype of Hybodus fraasi in the Museum für Naturkunde, Berlin, Germany.

Hybodus fraasi is a pre-historic shark that swam the oceans in the Late Jurassic. Fossilized teeth and dermal denticles of this species were found in the Early Tithonian of Solnhofen, Bavaria (~152 Ma).
. 
Hybodonts were a long-lived lineage of sharks that first appeared in the Famennian, Upper Devonian (~372 - 358 Ma), with fossil remains from central Iran dating this time, and got extinct at the end-Cretaceous, about 66 Ma.
. 
Hybodonts were the sister taxon (closest relatives) of the neoselachians (true modern sharks, rays and skates). They thrived in both marine and fluvial ecosystems.

  • A Caribbean Whiptail Ray scoots along the bottom alternately searching for pray and hiding from predators at Tiger Beach in the Bahamas. While not technically a shark, rays are in the same family as sharks, skates and sawfish. They are all members of the subclass of cartilaginous fish called Elasmobranchii. They share many of the same traits such as having 5 to 7 gill slits, rigid pectoral fins, skeletal systems comprised of cartilage and have placoid scales covering their body. 
Rays are a favorite food of the Great Hammerhead and the sandy areas around Tiger Beach are full of them so it’s no wonder the Hammerheads have been showing up a lot in the area during their annual migration to the Bahamas.
