Giant oceanic manta ray
Giant oceanic manta ray
Scientific Name
Mobula birostris
Weight LB
6600 Lbs
Average Life Span
20 years
Fact
Manta rays are giant, gentle filter-feeders with unique belly spots like fingerprints, the largest brain-to-body ratio of any fish, and the ability to "fly" out of the water, performing incredible acrobatics despite their massive size (wingspans up to 29 feet!). They constantly swim to breathe and feed on plankton, visiting "cleaning stations" for hygiene and displaying high intelligence, including recognizing themselves in mirrors.

Great White Shark
Great White Shark
Scientific Name
Carcharodon carcharias
Weight LB
1,500–5,000 lb
Average Life Span
30–70 years
Fact
A fun fact about great white sharks is that they are partially warm-blooded, allowing them to maintain a body temperature warmer than the surrounding water, which helps them hunt faster in colder seas, and they possess a "sixth sense" (electroreception) to detect the electrical fields of prey, even those hiding in sand. They also have rows of serrated, triangular teeth that can reach nearly 7 inches, and their skin is covered in tiny scales that reduce drag for speed.

Seahorse
Seahorse
Scientific Name
Hippocampus kuda
Weight LB
0.01–0.02 lb
Average Life Span
1–4 years
Fact
A fun fact about Hippocampus kuda (Spotted Seahorse) is that males get pregnant and give birth, carrying the eggs in a pouch until they release live young, and they often form monogamous pairs, performing courtship dances and changing colors to strengthen their bond. They are also poor swimmers, using their prehensile tails to cling to seagrass and ambush tiny prey with their tube-like snouts, needing to eat almost constantly to fuel their high metabolism.
