The tarpon may be described as a “euryhaline species” because it can survive in a wide variety of salinity and therefore lives in both the ocean and in fresh waters. The tarpon breeds mostly in the oceans in salt water. The females can lay up to 12 million eggs at once. They spawn their eggs between the months of March and July. Tarpons tend to swim upriver from the ocean and often inhabit rivers, creeks, tidal pools, and salt marshes. Some return to the ocean but others stay in freshwater locations.
