Squid

The sperm whale

Frog gills, primarily present in their larval stage as tadpoles, serve the function of extracting oxygen from water for respiration. These gills allow tadpoles to breathe underwater, facilitating their growth and development. As frogs mature and undergo metamorphosis, they lose their gills and develop lungs for breathing air. Thus, frog gills are crucial for the aquatic life stage of the amphibian's life cycle.

Sweetie the Squid and octupus always swims head first

@previous answer.. you're wrong. squid swim feet first. the 2 long tentacles and the 8 legs are actually near the head because the the arms and tentacles close around the mouth. so when they swim they open and close their arms & tentacles making them swim fin up. therefore, squid swim FOOT FIRST "sweetie"
