External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water. After the sperm reaches the egg, fertilization can then take place. Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time. The release of the reproductive material may be triggered by water temperature or the length of daylight. Nearly all fish spawn, as do crustaceans (such as crabs and shrimp), mollusks (such as oysters), squid, and echinoderms (such as sea urchins and sea cucumbers) . Pairs of fish that are not broadcast spawners may exhibit courtship behavior. This allows the female to select a particular male. The trigger for egg and sperm release (spawning) causes the egg and sperm to be placed in a small area, enhancing the possibility of fertilization.

What is type of fertilisation?
There are broadly 2 types of fertilisation - 1) Internal fertilisation - This mostly takes place in higher classes of animals like humans and mammals. In this the male transfers its gametes into the female body and the male gamete fuses with the female gamete inside the female body 2) External fertilisation - This is mostly seen in fishes. The male and the female both transfer their gametes into the external environment and the gametes fuse outside

What animals do external fertilisation?
External fertilization takes place when the sperm and egg meet outside the body. Animals that use external fertilization as a means of reproduction include salmon, stony coral, and many species of reptiles.
