A scale from the Linea Lateralis (lateral line organ)

Some fishes have a row of tiny scales on each side of their body, which works as a sensory organ, detecting vibrations in water. The little hole in the middle of the scale let the water penetrate under the scale, into a tiny canal which conducts the liquid in contact with the external structure of a sensory cells' group, connected to a nerve. The impulse that the nerve record depends on the pressure of the fluid : it can detect very low pressure variations, which allow the fish to perceive movements of other fishes around or to regulate its own swimming speed.

We’ve found out why a Mexican cavefish has no eyes – and the surprising answer is likely to be seized upon by those who think the standard view of evolution needs revising.

Over the past few million years, blind forms of the Mexican tetra (Astyanax mexicanus) have evolved in caves. Maintaining eyes and the visual parts of the brain uses lots of energy, so the loss of eyes is a big advantage for animals living in the dark. Instead the cavefish “see” by sucking.

It was assumed that these fish became blind because mutations disabled key genes involved in eye development. This has been shown to be the case for some other underground species that have lost their eyes.

But Aniket Gore of the US’s National Institute of Child Health and Human Development and colleagues haven’t found any disabling changes in the DNA sequences of eye development genes in the cavefish.

Understanding Biology

BIOLOGY as a natural Science deals with the study of nature. It is subdivided into the physical and biological sciences.Physical Science is the study of nonliving matter. it includes physics, chemistry,Meteorology, Volcanology, Astronomy and Geology. whereas, Biological Science is the science of life . such as the study of Plants (botany) and animals (zoology).

BIOLOGY as a whole has various fields of specialization. to name some, we have...

ECOLOGY - The study o f environment and the interrelationship of organisms in it. EVOLUTION - The study of the origin and differentiation of different kinds of oraganisms. TAXONOMY - Thes study of classification and naming of Plants and Animals. GENETICS - The study of heredity or how an organism's characteristics are transmitted from parents to offspring. PHYSIOLOGY - The study of normal functions of parts of an organisms. CYTOLOGY - The study of structures and functions of cells. HISTOLOGY - The study of tissues. MICROBIOLOGY - The study of microorganisms. BIOCHEMISTRY - The study of chemistry of living things. EMBRYOLOGY - The study of growth and development of new organisms. ANATOMY - The study of the parts or structures of organisms. PALEONTOLOGY - The study of fossils of living things and their distribution in time.

furthermore, BIOLOGY has a lot to offer! It has subdivisions in studying specific kind of organisms. we have,

ENTOMOLOGY - The study of Insects. HELMINTHOLOGY - The study of worms. ICHTYOLOGY - The study of fish. ORNITHOLOGY - The study of birds. MAMMAOLOGY - The study of mammals. CONCHOLOGY - The study of shells. ANTHROPOLOGY - The study of man. PARASITOLOGY - The study of parasites. BACTERIOLOGY - The study of bacteria VIROLOGY - The study of viruses.

Easter is a time for fresh starts and new energy, but we must never forget where we came from today I’m remembering fond memories while looking towards the future, like that time my dad took me fishing and we beat the absolute shit out of the fish, looking forward I’m considering a possible career in ichtyology in order to beat the shit out of even more fish
