Seahorse


here is a lesson to be learned from seahorse, but before that I shall do some justice to biology and explain a bit about these amazing creatures. Seahorses belong to the phylum Osteichythes, which literally means bony fish. Named as such because their skeletal structure is made of bone, Calcium and phosphate compounds. They have swim bladder that helps them with buoyancy and change in depth during swimming; all they do is regulate the amount of gas in the swim bladder. They also have gill coverings (called operculla) that regulates the amount of water coming or leaving the fish. This structure is the one that helps certain fish types to stay stationary without moving. If you watch Sharks and other aquatic animals closely, you will notice that they are constantly moving so they can have water moving through their gills for gas exchange, other wise they'd suffocate and die. But those found in the Osteichythes phylum have evolved a specialized structure, as mentioned above, to avoid suffocation. Having said this much about the phylum seahorse belongs to, lets get down to what made them stand out for me:

Lesson 1) With few exceptions, seahorses are monogamous. They work hard to strengthen their relationship and bondage. Both the male and the female toil during the day socialize during the evening.
2) It is the male that is impregnated. He is responsible for taking care of the embryos in a pouch-like structure in his abdomen until they hatch.

K, I just thought they were soo cute, and amazing little creatures. Hopefully the link below would work for anyone interested. (Its a male seahorse giving birth)
