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).
Some questions may people ask:
What animals have external fertilization?
• Many fish, amphibians, and other sexual aquatic animals use external fertilization (the exceptions are aquatic mammals, sharks, and some other special types of fish). External fertilization is beneficial because the mother does not have to physically carry the developing offspring.
What is external fertilization give examples?
• Externalfertilization is a case in which fusion of male and female gametes takes place in outside environment/ medium and not in the body of the female . for example, in case of frogs , fertilization takes place in water medium . the female releases eggs in the water at the same time sperms are released too.
What animals undergo internal and external fertilization?
Internal fertilization is followed by Mammals(including humans), Reptiles, Birds, Bryophytes and Tracheophytes, while external fertilization is followed by Amphibians, Algae, Fish, etc.
