A fish heart is located in the ventral position immediately behind the gills.
Here's a more detailed explanation:
- Location: The heart of a teleost fish resides within the pericardial sac.
- Position: This sac is situated on the ventral side (belly side) of the fish, right behind the gills.
- Chambers: The teleost fish heart is a four-chambered organ.
- Protection: The heart is surrounded by a relatively rigid pericardial sac.
In summary, the fish heart's specific location is ventral, directly behind the gills, encased in a protective pericardial sac.
