Dolphins:.With all the research on dolphins, we still don't know how they can swim so well with the hydrodynamics and physiology that they have, but fluid dynamics reveals amazing things about them. They too, like the housefly, are a conundrum

The dolphin continues to challenge our understanding of it. Dolphins can speed at 10 meters.(9 yards).a second, with muscles not powerful enough to overcome the water drag at that speed. How do they do it? They have the ability to achieve laminar flow at high velocity, with no turbulence over the dolphin's head 'sonar dome'. Such amazing design!

Compared to bats, dolphins have a very large brain, but the smaller brained bat has a much more sophisticated.echolocation system. Something more than brain size is going on.

Dolphins, whales, sea lions and seals as well as bats possess this amazing echolocation ability.

Findings by the Hawaii Institute of Marine Biology.(search at commondreams.org).may explain several strandings of dolphins and whales in the past decade. Most strandings are still thought to be natural events, but the tests strengthen fears that exercises by naval vessels equipped with sonar are responsible for at least some of them. 

Porpoises and dolphins have very different teeth, but in other aspects they are most similar. Their diversity can not be accounted for by the nutty theory of evolution.

Most types of dolphins possess dorsal fins, but why not the Northern Right Whale Dolphin?
   Dolphins are related to whales but are generally smaller and have a beak-like snout. 

Dolphins and seals hear without ears with fat bundles in the lower jaw and their connecting ear canals have a shape like an ear trumpet. Little ones respond to their mother's signature whistles.

Mother dolphins form playpens for the young to protect them. Dolphins cooperate when they feed, circling schools of fish and taking turns to dart in and feed. What motivates dolphins to keep herding fish, once they have satisfied their hunger? A good example of altruistic behavior. But it's balanced with some negatives. 

Dolphins engage in both positive and negative behavior. Negative in that they sometimes kill other species, but not for food and commit infanticide.(killing their young; perhaps because they sense a weakness that would put at risk the growing dolphin). Positive in that the adults play.(not common among adult mammals).and cement social relationships with sex.

The Atlantic Humpbacked Dolphin, common to the coastal waters of South Africa, is know for cooperating with fishermen by driving fish toward their nets. 

In summer when the water is the warmest, dolphins give birth, the mother lunging quickly away from her new born calf in order to snap the umbilical cord, thusly freeing her calf to swim to the surface for its first breath. Soon the calf is nursing, taking solid food in the form of fish after about 6 months. The nursing may continue for several years.

Young dolphins like to play and often toss Sting rays around like frisbees. Dolphins are sociable creatures and enjoy meeting humans.

Coral(s):.Coral is in fact a marine animal. Like sea anemones,.(findingcoral.com).hydra and jelly fish, they are polyps.(small flowerlike marine animals with a tubelike body). Cold water and deep water corals retain 'their pigments', which they in response to environmental stress. Why they do this is a mystery, as they don't need them for solar protection. They just look pretty! Corals live in large colonies.(many living together). Their skeletons form a stony mass, as only the top layer of a coral reef is living. As the individual polyps die, their calcium carbonate skeletons remain. Tiny ocean corals' calcified bodies provide the infrastructure for their descendants. Atolls.(means 'uniting', as in a ring shaped coral island surrounding a lagoon).of coral are found in many tropical seas.

Many coral so beautifully fluorescesuch vivid colors and yet, so much more so than other animals. The color of the coral comes from the different types of algae which inhabit different depths.

The highly poisonous Lion Fish keeps the coral reef safe from poachers. Fish maintain the balance of algae growth, so the algae doesn't choke the coral.
   Coral have the ability to turn their innards outward, discharging them at enemies.

Corals have a symbiotic relationship with algae upon which it depends 80% for its nutrients, but algae abandon coral when the temperature rises above 30ºC. Algae use the carbon dioxide emitted by the coral's orifice.(hole,.which, interestingly enough, acts as both mouth and anus).to photosynthesize oxygen and food in return for the carbon dioxide. The whole scenario is truly Gaian and altruistic! Production of carbon and other elements making Earth life possible entails a sensitive balance of physical equational constants.

Parrot Fish:.Parrot fishes can cloak.(something that covers or conceals).themselves in their own mucous.secreted from their mouths. These bubbles from their mouths mask the sleeping Parrot Fishes from night prowling morays.(eels.inhabiting.coral reefs, that feed on fish like Parrot Fish).

To become the dominant one in the social order of reef fishes, Parrot fish compare the size of their opened mouth, a behavior known as gaping.
   Parrot fish look today as they did in ancient times. No evolution for them, or anything else for that matter.
