Because of the process of osmosis, whereby water diffuses from an area where it has low concentration to one where it has high concentration.
The metabolism of marine fish is different from that of Freshwater Fish, in that they are specifically adapted to live in waters containing a high salt content. As a result, their bodies contain less water- they have less in their bloodstream, and a higher content of salt in their tissues and organs.
When placed in freshwater conditions, water will naturally diffuse from it's high concentration to the area where it is of low concentration- the tissues and body of the fish. As a result, the poor animal's body tisues and organs become engorged with water, resulting in rupture, haemorrhanging and the eventual 'bursting' of the creature's body.
For this reason, it is very important when keeping a tank of marine fish (be they tropical or otherwise) that the salt content of the water is VERY carefully carefully balanced. It must be in equilibrium with the fish's own internal salt and water balance- too little salt, and the above situation can happen, but too much salt in the water, and the reverse can take place, whereby the fish contains more of a water concentration than the surrounding water, and become dehydrated and die.

If enough water pressure build under the surface of the ground, the water can burst through cracks in the surface forming a geyser.
A marine biologist studies under water creatures.

If they are grey and fertile, they will burst upon contact with the salt water, and you will have little planktonic zoeae swimming around. Unless you have a cycled marine tank with a sponge filter, you have no hope of raising them through 5 larval stages to adulthood, and you should throw them out. if the eggs are red, and did not hatch in the salt water, they are not fertile. Just thrown them away.
I can't think of any reason it would "burst" under those conditions.
it lives under the water and land
well i was wondering too
under water spideer!

If stored under pressure and then quickly released it can burst out as steam.
