Medusozoa

Jellyfish or jellies are softbodied, free-swimming aquatic animals with a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate to acquire propulsion and locomotion. The tentacles may be utilized to capture prey or defend against predators by emitting toxins in a painful sting. Jellyfish species are classified in the subphylum Medusozoa which makes up a major part of the phylum Cnidaria, although not all Medusozoa species are considered to be jellyfish.

Medusozoa is the scientific name for what are commonly and incorrectly referred to as jellyfish.  They are free-swimming carnivorous marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles.  Medusozoa (or jellies) are found in all ocean waters at all depths, but most commonly in coastal waters.  They are the oldest multi-organ animals, dating back more than 500 million years.  While they have multiple organs, these organs tend to be, for the most part, relatively primitive.

The umbrella mass is covered on the aboral surface by a thin close-fitting layer called the epidermis.  Beneath the umbrella mass is another layer of skin, called the gastrodermis.  The gastrodermis is attached to the umbrella mass only along the edges.  At the center of the gastrodermis is the mouth, where food (primarily plankton, crustaceans, and fish eggs) are ingested.  Between the umbrella mass and the gastrodermis is the gastrovascular cavity where digestion takes place.  

Medusozoa have a loose network of nerves, primarily sensing touch, and some species have primitive light-sensing organs.  They move by radially expanding and contracting the umbrella mass, pushing water behind them.  Tentacles (over 100 feet long in some species) hang from the edges of the umbrella mass and from the gastrodermis.  The tentacles contain stinging structures, called nematocysts, used to pierce the skin and inject venom into prey (or predators).  Triggered by physical contact, a lance inside the nematocyst pierces the skin and venom is injected.  Different medusozoa have evolved different lances and venom, depending on feeding habits and its particular biosphere.  Some of these venoms are particularly painful to humans.  

The venom of several species can be deadly to humans, causing anaphylaxis (a severe allergic reaction affecting a number of body systems at the same time).  Application of a vinegar wash is a common first-aid treatment, followed by careful removal of nematocysts for the affected area and administration of antihistamines.  The pain, sometimes excruciating, may last for several hours.  Wearing of wetsuits is generally effective in preventing medusozoa attacks.

The Food Of Hell From Indonesia


Famous as one of the best tropical countries, Indonesia provides tons of uniqueness and excitement. Its nature, culture, and art always bring millions of tourist each year. However, this time we are going to talk about one thing, Indonesia’s cuisine, in particular Sambal.
Sambal or sambel is infamous among tourist as the food of hell for its undeniable ability to make the consumer produces tears and sweat when eating. Produced using chili as its main ingredient, sambal is indeed taste extremely spicy.
Sambal is made by grinding ‘cabai’ or chili, along with several complements such as onion, cherry,  tomato, ‘terasi’, sugar, and salt. The ingredients are grinded using traditional tool made usually from wood or plastic. Sambal can be served raw or cooked. The texture is smooth with a vibrant color of green and red, depending on which chili you use.

Infamous among tourists for its spiciness, many tourists avoid it. However, some of them are challenged and try to eat it. Those who dare to try usually will get stomach ache or turn very red and sweaty in the face. Though super spicy, locals eat it in almost daily basis as their main meal.

In the Indonesian archipelago, there are as many as 300 varieties of sambal. The intensity ranges from mild to very hot. Some varieties include:
Sambal andaliman
Similar to sambal lado mudo but with the addition of andaliman pepper.
Sambal asam
This is similar to sambal terasi with an addition of tamarind concentrate. Asam means tamarind or sour in Indonesian.
Sambal bajak (badjak)
Banten sambal. Chili (or another kind of red pepper) fried with oil, shallot, garlic, terasi, candlenuts, palm sugar and other condiments. This is darker and richer in flavor than sambal asam.
Sambal balado
Minangkabau style sambal. Chili pepper or green chili is blended together with garlic, shallot, red or green tomato, salt and lemon or lime juice, then sauteed with oil.
Sambal buah
