Back to Basics- Fish

Back to Basics- Fish

Time to brush up on your fish knowledge with professor Sylvia the Seahorse!

Number of fish species- 24,000 and growing! Scientists discover new species all the time! We fish were the first vertebrate animals on the earth! We occupy the world’s oceans and fresh water bodies of water; including lakes, rivers and ponds.

Fish traits:

  • Fish have gills that we use to extract oxygen from water and expel carbon dioxide. They serve the same function as a mammal’s lungs.
  • Fish have scales. Our scales are different, some are smooth and some are rough. Sharks’ scales are called dermal denticles. Some fish like hagfish have no scales.
  • Fish have fins for swimming. Fins are shaped for the type of swimming a fish does- some are built for speed and some are small (like mine).
  • We fish are vertebrates, we all have back bones.
  • Most fish are exothermic, cold blooded.

Fish are classified in three groups; jawless fish (hagfish and lamprey- they also have no scales), cartilaginous (sharks and rays) and bony.

Some fish lay eggs, some incubate their eggs in a womb and some incubate their young in wombs similar to mammals.

We fish can detect chemicals and vibrations. We often have keen eyesight and a great sense of smell.

Fish do have ears! Not big goofy ones like some mammals, but internal ones.

We also have an extra “organ” to help us “hear” and detect vibrations. This is called the lateral-line. This line of cells runs the length of our bodies and helps us detect motion. Schooling fish who swim in synchronized groups use their lateral line to swim in these formations.

Sharks and rays have yet another “organ” that helps them detect electrical fields. It’s called the ampullae of Lorenzini, gel filled cells that help our cartilaginous cousins detect even the faintest of electrical fields. This is something no other animal can do!

We also have a swim bladder that keeps us buoyant in the water. Fresh water fish have a bigger swim bladder than salt water fish. Bony fish swim bladders are filled with a gas that is less dense than water. In cartilaginous fish, their swim bladder is a large oil rich liver that is less dense than water!

Pocket Sharks have two pouches or pockets, one on each side of their body in front of their fins. Scientists are unsure of their purpose.

Bamboo Sharks are mostly nocturnal and only grow up to 37 inches long.

Zebra sharks lose their stripes as they grow. Adults are actually covered in spots!

These large sharks (up to 14 ft) often rest on the ocean floor. They pump water over their gills using spiracles to pull in water.

Our week of diving is continuing at camp and we are meeting a seahorse- or a SeaEdmond as we like to call them! Everyone ready? Grab those flippers and let’s goooooo!

Lined Seahorse Fun Facts:

  • Their eyes can rotate around and move independently of each other.
  • Males are larger and have longer tails than females.
  • They mate for life.
  • Like other seahorses, the males incubate the eggs in a pouch. They give birth to the baby seahorses. They are about the size of a flat thumbtack.

Peacock in the Ocean

Peacock in the Ocean

We’re loading up the SS E&E- our research boat with campers for the next three days as we head out to sea! It’s time for all our campers to grab their scuba gear and go diving! We’re exploring the ocean floor today! If we’re looking for a flat fish, so keep those eyes peeled for the Peacock flounder!

peacock flounder

Peacock Flounder Fun Facts:

  • They are known as the flowery flounder.

  • Peacock flounders prey on crabs, shrimp and small fish.
  • Peacock flounders have specialized skin cells that allow them to change their color to match their surroundings! They can do this in as little as 8 seconds.

Peacock flounders are amazing animals! These flat fish are masters of camouflage! We are glad our campers were able to spot a few! Hehehe!

Blind in the Cave

Blind in the Cave

We are enjoying spelunking with the campers this week! Deep in the cave there is a lake, it is part of the same system of water that makes up Lake Salamander! It is in the cave lake we can find some of the most interesting and alien like animals on the earth! Make sure you have on your head lamps campers!

blind cave fish

Blind Cave Fish Fun Facts:

  • These little fish only get up to 4 1/2 inches long.
  • Blind cave fish have lost their ability to see and some of have even lost their eyeballs. Crazy right!?
  • They use their lateral lines along their bodies to get around. Those lateral lines detect different kinds of pressure.
  • They eat bat droppings.
  • Scientists think the fish lost their eyesight to reduce energy use!

These little fish were such a fun find! Woohoo! Camp is just the best!

It is always fun to spot some barracuda! We like to wave and swim the in the other direction. They may not be aggressive, but those teeth don’t say let’s be friends.
