Ozeane für Dummies
Erkunden Sie die unendlichen Weiten der Ozeane, wie sie funktionieren und welche Kreaturen dort leben. Ashlan und Philippe Cousteau erklären Ozeane von der Pike auf bis zum Blauwal. So lernen Sie alles über Phytoplankton und wie es den Ozean mit Sauerstoff versorgt, die Nahrungskette der Meere und wie Strömungen unser Klima kontrollieren. Aber auch wundersame Kreaturen gehören zu diesem Ö Der Fangschreckenkrebs, der mit der Schnelligkeit einer Pistolenkugel zuschlägt, ist genauso dabei, wie der Riemenfisch, der bis zu acht Meter lang wird und so scheu ist, dass ihn kaum jemand je zu Gesicht bekommt. Jeden Tag entstehen neue Wunder, die es zu entdecken gilt!

Rainforests supply only about 28% of the oxygen on our planet… the other roughly 70% comes from the sea
Bathypelagic zone (midnight zone: the 3/5 layer, the abyss and the trenches follow). No sunlight penetrates this zone. The creatures that live here are too insane to make up, but they're not the most colorful - just about everything is black or red, which makes them virtually invisible in water at these depths.
A red tide is a HAB caused by certain types of algae, particularly toxic red dinoflagellates and diatoms, that turn the water rust-red to orange (hence the name). During a red tide, the algae produce and release massive amounts of toxins, such as brevetoxin, saxitoxin, and domoic acid (all nasty stuff). These toxins can cause paralysis; tissue damage; seizures; impaired muscle movement, balance, or orientation; respiratory irritation; and death. Along with the resulting hypoxic or anoxic conditions, these toxins are often responsible for mass die-offs of fish and other marine life and are extremely dangerous to humans who happen to live nearby as well.
The Octopus is regarded as one of the most intelligent creatures in the sea, and the most intelligent invertebrate on Earth thanks to its large brain. It’s also a tool user and can learn and remember. Has 3 hearts: one heart pumps blood through the body, while the two small hearts pump blood to the gills. An octopus will always beat you at a game of hide and seek. They're able to change their color and texture to match their surroundings to a T.
An octopus is smarter than a squid, but squids are better swimmers.
The largest fish in the sea, the whale shark.
Alligators are usually grey and black, whereas crocs are olive or tan. An alligator’s snout is shorter and wider than that of a crocodile, and their "smiles" are different. With alligators, you're not likely to see their pearly whites unless they open their mouths, whereas a croc's teeth are usually visible even when its mouth is closed.
Many marine mammals have kidneys that are more efficient than human kidneys at filtering out salt from water.
Deadly Ocean Creatures
Saltwater Croc: they’re aggressive they clamp down and won't let go. Third, immediately after clamping down, they do a death roll to drown and dismember the body.
Fugu Fish (blowfish): has a toxin in its liver that makes taste horrible and is potentially deadly
Killer Whales
Blue-Ringed Octopus: their bite contains the powerful neurotoxin called tetrodotoxin (the same toxin carried by the fugu pufferfish). They’re immune to their venom
Sea Snake
Stone Fish: The stone fish holds the title for most venomous fish in the world, but you may not even notice them, because they look like rocks. At least not until you step on one. The first sign of trouble is that your foot becomes impaled on the spikes of their dorsal fins (exceedingly painful). Then, the toxin enters the bloodstream, causing swelling around the wound, difficulty breathing, irregular or no heartbeat, nah-sea, vomiting, delirium, and even death.
Sharks (some of them): great whites, tigers, bull, oceanic white tip
Cone Snails: contain venom to kill 700 people
Box Jellyfish: They deliver their venom on contact, and a sting from the most venomous of the group can result in paralysis, cardiac arrest, or even death in a matter of two to five minutes
First, it's true that sharks must swim to keep from sinking. They do, however, have an oily liver which makes them close to neutrally buoyant, but they will still sink, albeit slowly.

Comprehensive basic survey of the ocean. Clearly written and logically laid out, with interesting facts interspersed within each section, a very good overview for someone like me who was unaware of the depths of my ignorance regarding the ocean system until recently. Unless you are already well versed in this subject, you will probably learn a lot from this book. I finished this book with a much greater appreciation of the worlds oceans and thought the authors did a great job keeping it interesting as an overview while still being scientifically accurate. The sense of wonder and enthusiasm for the subject pervades what is essentially a basic oceanic science textbook, great job Costeaus!

Als aardling heb ik met plezier het vlot en plezant geschreven en te lezen boek met verwondering gelezen , ( ik wist niets over oceanen en wat daar in / op en rond gebeurde ) dus was er veel bij te leren over deze fascinerende wereld, ( voor mij is het een beetje een andere wereld ). waar zwaartekracht een andere invloed heeft en het leven er anders en een beetje hetzelfde is als op het land , boeiend hoe alles op elkaar inwerkt , 5 zeesterren ook voor iemand die nog nooit van oceanauten gehoord heeft

This book is a great place to get started to learn more about our oceans. It contains a lot of great information. Well done.

This was a great overview of the ocean and it introduced me to many facts I didn't know about, especially lots about different kinds of sea life.
It is good for getting a taste of the ocean and absorbing lots of interesting information rather than diving deep (whoops) on any one marine topic. But that's what I really wanted.
The passion of the authors is very apparent. It's written in an easy, conversational and accessible style - some may find it a little too casual and jokey if they want a more serious study of the ocean, but the style makes it fun to read and easy to take in the huge amount of data.
The writers have a clear agenda in writing about the ocean - as well as introducing you to their passion, they care about protecting the ocean and have obvious ideas about sustainability and environmentalism. I doubt many people would find this in any way offensive however it should be noted that this book is not just facts about the ocean and what makes it up etc, but a book about ideas about how the ocean ought to be used.

I grew up basically in the ocean but wanted to learn more and this book was amazing!
