Hot Weather effects
Breathing
Did you know fish are a lot like humans? Yes, we breathe easier in cool weather than on hot humid days; too much water in the air and not enough oxygen. Fish breathe better in cool water because there is more oxygen in cool water. So that's one of the reasons why our finned friends, and you and I, feel a little tired during hot days. Will wonders never cease.
 Fish Scales
I always wondered how fish scales grew and from where. "The mystery has been solved." Through careful scrutiny, I see that scales grow from pockets in the skin. Also, when looking at scales, the approximate age of the fish can be determined by counting the ring patterns formed on the scale. Each year of growth creates a new line. Neat information, isn't it?
 Sawfish
Do mother sawfish worry about giving birth to young saw fishes? Remember, each baby has a saw. How do they accomplish the seemingly impossible feat of birthing those little twerps without them getting stuck on the way out? Are you ready for this? I saw a saw-fishes saw before its birth and found it was enclosed in a protective sheath that is shed soon after its birth. That certainly eliminates the "ouch" factor, doesn't it?
Seals
Have you ever seen a seal drink sea water? Probably not. A seal would become very sick, as would humans. How do they receive moisture? They obtain enough liquids from the food they eat. |

 Fish Reproduction
As long as we are on the subject of babies and birthing, it may be of interest to know, there are three modes of reproduction found in fishes:
** parthenogenetic
** heterosexual
** hermaphroditic
Hmm, it sure sounds complicated doesn't it. How on earth do the fish do it. Gotcha, didn't I, it's done in water.
Sharks
Documentary videos about sharks sometimes shows small fish swimming in front of and off to the side of sharks. The pilot fish, the culprit, is the smart one when it comes to utilizing a unique condition. They are clever, by using the under water waves created by the rapidly swimming sharks; the effect is like riding the waves like a surfer, which conserves their energy. Ingenious, wouldn't you say?
Grunts
There is a fish that is caught in Florida waters called "grunt." The word
comes from the sounds made when brought on board when catching or handling, and
probably happens a lot in their natural activities when swimming and feeding. How do these
sounds erupt from their mouth (not recommended by you unless you do not mind a trip to the
dentist or doctor)? They grind their teeth together (no cavities I hope) which sounds like
a human grunt. But they go a step further and amplify the sound much louder by utilizing pressure
from their air bladder. This sounds like a good burp, with a little stomach gas to boot.
