As the name entails
Are partial to mammals
Especially other animals

Deer and seals
All become meals
Also white shark
Reality quite stark

Top ocean predator
A killing pre-meditator
Kills efficient
Not complacent

Tall dorsal pose
Brings ocean of prose
Life at sea
Efficiently

Close knit family
All related genetically
Range afar
As pantry ajar
Seeing takeaway meals
Plays with seals

Kind side of matriarch
Young calves play the lark
Frolic in the open ocean
Dorsal strong with constant motion

Hope to see black dorsals tall
Now we've seen your signals small
Intriguing sound
On Sonix found

Not complex
Small intonation flex
We seek the lion of the sea
A truly oceanic beasty
