Fish & Crustaceans

With tens of thousands of different species, fish and crustacean behaviors, habits and abilities vary wildly.  Typically, fish can be defined as cold-blooded, aquatic vertebrates.  They usually have streamlined bodies, breathe underwater through the use of gills, have two sets of paired fins, have a jaw and have skin that is covered with scales.   Fish have an important role in many cultures, including ours, ranging from being seen as religious symbols to subjects of books and popular movies.

Did you Know?

Fish have been around for 500 million years, which means they were well established long before dinosaurs roamed the earth!

Fish have excellent senses of sight, touch, taste and many possess a good sense of smell and 'hearing'.

Fish don’t sleep like humans do, as they don’t have eyelids, but they do rest.

Recent studies have shown how fish perceive pain.

Most fish breathe underwater by exchanging gases over their gills. When fish open their mouths, they pull oxygen-rich water in and across their gills. When they close their mouths, oxygen in the water passes into their blood, through blood vessels on the gills. 

Fish suffocate when taken out of water.  Fish need water to hold their gills open, when taken out of water, their gills collapse and they are not able to take oxygen into their body.

Some fish, such as eels, catfish and bowfin, can actually breathe air through their skin and/or their organs! 

Tuna-like fish and certain sharks can swim 50 miles per hour in short bursts!

Fish use their fins to stabilize themselves and as an extra tool to propel themselves forward.




Several crustaceans are consumed by humans, the vast majority of which consists of crabs, lobsters, shrimp and prawns.  Crustaceans are characterized by their jointed appendages and hard shells.  Most live in either fresh water or marine environments, but a few have adapted to life on land, such as terrestrial crabs.

Lobsters live for about 15 years, and some may live to be 100!

Lobsters have a pair of pincers called chelapeds, or claws, one being a heavier crusher claw and the other a smaller feeding claw. 

Lobsters live anywhere from 10 to 600 feet beneath the ocean’s surface. 

Lobsters have tiny hairs that cover their entire body. These hairs are not only sensitive to touch, they also act as taste buds. 

Lobsters possess a short set of antennae which allow them to receive chemical signals carried by the seawater.  Some researchers believe that receptors on the antennules enable lobsters to detect the species, sex and even mood of other animals nearby.  

The longest distance ever traveled by a lobster was 225 miles!

Lobsters are primarily scavengers. Their typical diet is comprised of clams, crabs, mussels, and worms.
