Beautiful Sea Dragons-dads raise the babies




Sea Dragons are some of the most ornately camouflaged creatures on the planet.
Adorned with gossamer, leaf-shaped appendages over their entire bodies,
they are perfectly outfitted to blend in with the seaweed and kelp formations
they live amongst. Endemic to the waters off south and east Australia, leafy and
weedy sea dragons are closely related to seahorses and pipefish.

Leafies are generally brown to yellow in body color with spectacular olive-tinted
appendages.

Weedies have less flamboyant projections and are usually reddish in color with
yellow spots.

As with sea horses, sea dragon males are responsible for childbearing.
But instead of a pouch, like sea horses have, male sea dragons have a
spongy brood patch on the underside of the tail where females deposit their
bright-pink eggs during mating. The eggs are fertilized during the transfer
from the female to the male. The males incubate the eggs and carry them to term,
releasing miniature sea dragons into the water after about four to six weeks.

Poison Dart Frogs-beautiful little jewels


















The family dendrobatidae is composed of the genus Dendrobates, Phyllobates, Epipedobates, Minyobates, Colostethus and Aromobates. They live in tropical forests from Nicaragua to Bolivia and you can find them from sea level to 2.600 m. in the Venezuelan mountains ("Tepuis") as is the case of Epipedobates rufulus.

The skin of these frogs has a powerfull poison and, normally, they've striking colours and patterns to advertise its predators they're dangerous, this is called aposematic coloration. The poison is very strong in the case of Phyllobates terribilis, P.auratoenia and P.bicolor. These three species could be very dangerous even for humans. Some tribus of Colombia use them to poison their darts to hunt, it's instantaneous and it lasts for a long time in the darts. The captive breed poison dart frogs don't have this toxicity because the diet we give them in our terrariums lacks some alcaloids or another chemical compounds which are the precursors of the poison.

As a rule these frogs adapt and breed well in captivity. Its wonderfull coloration, the elaborate and nice mating methods and the diurnal activity make the poison dart frogs a desirable subject for the terrariums. A big number of people breed them in captivity.
