It’s not a jellyfish! The Portuguese Man o’ War may look like a bloated jellyfish, but it’s actually a siphonophore—a bizarre group of animals that consist of colonies made up of dozens, hundreds, or even thousands of genetically-identical individual creatures.
Not much is known about the Spiny Devilfish, but what is known mostly revolves around it’s spines. It has poisonous spines on the dorsal, anal and ventral fins. This fish is predominantly well camouflaged (and so easy to miss) and lies buried up to the eyes and mouth, waiting for prey to swim by to ambush by lunging forward and inhaling their prey with their large mouths.
Probably the most remarkable fact about the Jewel Fish, however, is the relationship of the mated couple, which comes as close to a “married life” in the full sense of the word as can be found among fish.
Seals spend much of their life in water! Their thick fur and blubber offer protection against freezing temperatures. Seals have more blood in their body than other animals. Since blood cells keep the oxygen, seal can dive longer than other animals. Seal can hold its breath for 2 hours which is a record in the animal world. They can dive up to 1000-1300 feet deep when they are searching for food.
Algal blooms are one common source of thick sea foams. When large blooms of algae decay offshore, great amounts of decaying algal matter often wash ashore. Foam forms as this organic matter is churned up by the surf. Most sea foam is not harmful to humans and is often an indication of a productive ocean ecosystem. But when large harmful algal blooms decay near shore, there are potential for impacts to human health and the environment.
Swimming with dinosaurs! Longnose Gar (and other species of this family) are ancient fish perfected suited to thrive in conditions that would easily kill most fish. They can gulp air when necessary, allowing them to survive in low oxygen and higher salinity water than most fish.
In some instances, however, the negative ecological impacts of artificial reefs may outweigh potential economic gains. For example, development of artificial reefs may cause an increase in overall visitation to an area, meaning more visitors to both artificial and natural reefs.
They can match the colors and even textures of their surroundings, allowing them to hide in plain sight. If a predator gets too close octopuses can escape quickly, shooting themselves forward by expelling water from a muscular tube called a siphon.
This Sea Slug, called the Costasiella usagi, or Strawberry Slug, is very rare to see. Because of that, not much information about their behavior is known. This tiny and superbly camouflaged slug is often found on solitary fan greens seaweed, which they also feed on. At low tide, many slugs are often seen on one sea fan, usually clustered near the base of this seaweed
Also known as the paiche or the pirarucu, the arapaima is an air-breathing fish that plies the rainforest rivers of South America's Amazon Basin and nearby lakes and swamps. They have primitive lungs which allows them to breathe air from the surface and gills that allow them to breathe underwater. Their bodies have adapted due to the low oxygen levels in their habitat.
