Shells continue to grow as mollusks grow, so the length of time it takes to produce a shell can vary from species to species. Many mollusks go through a larval stage in their development, so the actual start of shell production can differ among species as well. What Are Shells Made of?
Ambient levels of nonionizing electromagnetic fields (EMF) have risen sharply in the last five decades to become a ubiquitous, continuous, biologically active environmental pollutant, even in rural and remote areas. Many species of flora and fauna, becau
Marine Food Webs: The food webs in the ocean often contain many more trophic levels than those found on land as in the ocean there are many different sizes of fish and other species that in turn prey upon successively smaller species. This means that for top-level predators, their diets po...
Scientists have watched the mollusk transform into more than 15 different species, including stingrays, jellyfish and lionfish [source: Hemdal]. To take on the appearance of the flat and poisonous sole fish -- one of its most impressive impersonations -- the mimic octopus draws all of its arm...
Scientists are now discovering the extent to which aquatic animals produce sound, and the role that their grunts, pops, growls and whines play in communication. For instance, we now know that many commercially important fish species, like cod and haddock, choreograph their complex courtship displays...

There are three species that grow to massive proportions: the giant (Architeuthis dux), the colossal (Mesonychoteuthis hamiltoni) and the jumbo, also known as Humboldt (Dosidicus gigas). While many squid are a few inches long, giant and colossal squid are enormous. The two types are ...
For the first time, scientists have sequenced the genome of the mysterious giant squid, finding answers about the creature's massive size. Here's the truth.
There are many theories as to why human and non-human species have evolved this physiological trait, however many center their conclusions around asserting dominance or appearing more attractive to a potential mate, according to the journal Philosophical Transactions of the Royal Society B. In ...
