What Are Jellyfish (Jellies)? Cassiopeas frequent mangroves throughout the Keys.
Credit: Dauphin Island Sea Lab / Wikipedia Commons Fortunately, the most common jellyfish in the Florida Keys, the Cassiopeas (Cassiopea fronosa or Cassiopea xamachana) tend to give only a mild sting. Their tentacles are upward facing, giving them a characteristic upside-down appearance. As they are common among mangroves, they are sometimes called the ‘mangrove upside down jelly.’ The cannonball jelly (Stromolophus melegris), another species found in the Keys’ waters, also tends to have little or no sting. A common springtime jelly is the sea thimble (Linuche unguiculata). Swarms of moon jellies occur from August to October. From late August until October, the translucent moon jelly (Aurelia aurita) is a common site. Though not a true jelly, the Portuguese man o’ war (also called a bluebottle, Physalia physalis) can drift into the Keys and South Florida during the winter, when there are strong winds from the south.
More Animal Facts. The Uniquely Talented and Intelligent Octopus. The octopus has advanced intelligence despite 500 million years of separate evolution from mammals, birds, insects and reptiles.
Octopus ancestors are, perhaps, the first intelligent beings on Earth. Recent research is beginning to describe their very unusual talents, behavior and brain, as well as their unique genetic makeup. The fact that such an intelligent creature has no bones or spine has upended theories of animal intelligence. This post will describe recent research about their unique brain and its similarities and differences from humans. Cephalopod Biology. Hanlon Lab – Hanlon Biography. Roger T.

ON AN UNSEASONABLY WARM day in the middle of March, I traveled from New Hampshire to the moist, dim sanctuary of the New England Aquarium, hoping to touch an alternate reality.
I came to meet Athena, the aquarium’s forty-pound, five-foot-long, two-and-a-half-year-old giant Pacific octopus. For me, it was a momentous occasion. I have always loved octopuses. No sci-fi alien is so startlingly strange. Here is someone who, even if she grows to one hundred pounds and stretches more than eight feet long, could still squeeze her boneless body through an opening the size of an orange; an animal whose eight arms are covered with thousands of suckers that taste as well as feel; a mollusk with a beak like a parrot and venom like a snake and a tongue covered with teeth; a creature who can shape-shift, change color, and squirt ink.
Not long ago, a question like this would have seemed foolish, if not crazy. I had always longed to meet an octopus. Occasionally an octopus takes a dislike to someone. Outlook Web App. Larger Pacific striped octopus - Wikipedia. The larger Pacific striped octopus is a species of octopus that has received recent media attention for to its intelligence and gregarious nature. Unlike other octopus species which are normally solitary, the larger Pacific striped octopus is reported as forming groups of up to 40 individuals. And while most octopuses are cannibalistic, and have to exercise extreme caution while mating, these octopuses mate with their ventral sides touching, pressing their beaks and suckers together in an intimate embrace. The larger Pacific striped octopus is very different from other species in other ways as well.
While most octopus species reproduce only once before entering "senescence" and dying, mothers in this species can mate and gestate many times throughout their lives. The larger pacific striped octopus has only been seen in a few locations off Nicaragua in murky intertidal waters near the mouths of rivers. This is a very rare octopus.

The California two-spot octopus (Octopus bimaculoides), often simply called a "bimac", is an octopus species native to many parts of the Pacific Ocean including the coast of California.
One can identify the species by the circular blue eyespots on each side of its head. Due to their friendly temperament and relative hardiness, most experts consider them the best pet octopus. Bimacs usually live to be about two years old. Common octopus - Wikipedia. The common octopus (Octopus vulgaris) is a mollusc belonging to the class Cephalopoda.

Description Dorsal (top) and ventral views of adult Misidentification Doryteuthis opalescens is very similar to two other species of squid in the same family: Doryteuthis pealeii from the North Atlantic Coast of North America, and Loligo gahi from the coast of Chile. Life history Paralarvae of D. opalescens hatch from the eggs and immediately begin swimming.
By the time D. opalescens reaches 15 mm mantle length (about 2 months old) they are strong enough to swim in shoals. Adult D. opalescens move off the continental shelf by day and can be found to depths of 500 m. Lolliguncula brevis - Wikipedia.
