The crown jellies, Coronatae, belong to the Scyphozoans, a class of jellyfish counting some 200 species, many of them stunningly beautiful.
Read moreThe Micronesian Shark Foundation has now been tagging grey reef sharks for over two years.
Read moreBeforehand, the organizers doubted whether it would be possible to find more species than last year, when participants identified what was at the time thought to be an almost unbeatable number of species: 36 nudibranchs and 4 other ophistobranchs.
Read moreIt was a huge 14ft (4m), 2,175-pound (987kg) female. Her body was sleek and muscular, capable of high speeds if necessary. She ignored the bait and gave the caged divers a once over then slowly swam away, never changing her pace.
Read moreGiant kelp is one of the fastest growing plants in the world. When conditions are good, kelp can grow two feet per day! Giant kelp prefers water temperature in the 50-65°F range.

Read moreFor those who are familiar with Big Pine Key and know that it is located in the middle of the Florida Keys in the southeastern United States, you may be thinking that this story is made up.
Read moreWhilst the largest marine park, The Phoenix Islands Protected Area is backed by institutions such as New England Aquarium and Conservation International, to protect some of the last pristine coral reefs on the planet, the tiny Brazilian state mari
Read moreIn the early part of their life cycles, after some days out in the blue as pelagic larvae, anemone fishes settle on the coral reef once they find a suitable host sea anemone.
Read moreThe extent to which alternate states are stable or reversible is presently not well understood. Such a process during which an otherwise stable ecosystem changes into another stable state is called a phase shift.
Read moreIn a completely different context, this ability also enables us, for example, to keep ourselves and our clothes clean and free from pathological bacteria, thus helping us to maintain good health.
Cephalopods have inspired legends and stories throughout history and are thought to be the most intelligent of the invertebrates. Some can squeeze through the tiniest of cracks. They have eyes and other senses that rival those of humans.

Read moreInitially, planktonic life forms looking for a permanent home attach themselves to every available inch of real estate. Larger invertebrates like snails and small crabs soon follow and begin grazing on the newly seeded decks.
Read moreThe absorbtion of CO2 may have slowed global warming, but there has been a resulting change in seawater chemistry. To understand why the effect of increasing atmospheric CO2, which leads to increased absorbtion of CO2 in sea water, is important, it is necessary to understand some of the chemistry of carbonic acid and its salts. However, before we can discuss the effect of this acidity, we must have a useful description of what we mean by acidity and acid strength. The most common and useful unit to describe the magnitude of acidity is the pH value.
