other Types of rays (not to confuse them with)
In the family of rays, manta rays are the largest ones.
Manta rays are very closely related and often confused with stingrays, eagle rays, bat rays, cow rays, etc.

The difference between reef mantas and giant manta rays
There are two types of mantas: reef mantas (mobula alfredi) and pelagic manta rays (mobula birostris). The latter is also called “giant manta ray” or “oceanic manta ray”, or sometimes “the great manta ray”.
Oceanic mantas are larger and migratory – whereas reef mantas are smaller (but still huge!) and live in shallower coastal habitats.

General characteristics of manta rays
What do manta rays look like?
Manta rays have large, triangular-shaped pectoral fins on either side of their body which looks like wings when they swim.
They have a flattened, diamond-shaped, disk-like body. Reef manta rays are primarily gray and black on the top (dorsal side), and mostly white on the bottom (ventral side), with batches of black pigmentation.
The patches of black spot patterns, as well as other unique physical characteristics, allow us to identify and monitor individual manta rays over time. Most of the manta rays are given a name when we first identify them. Several organizations keep track of manta rays and their movement worldwide; we keep our own database of manta rays spotted around Kona in Hawaii.
How big are manta rays?
Adult reef manta females measure up to 12-14 feet (from wingtip to wingtip). Mature males are smaller, up to 10 feet.
Giant oceanic manta rays can have a wingspan of up to 22 feet wide. A picture of unknown origin from 1920 shows a manta ray that measured approximately 30 feet.
We can only estimate how much manta rays weigh; depending on the gender and the type (giant or reef manta), most would weigh between 50 and 100 lbs (between 22.5 and 50 kilos) per foot of manta ray.
How old can manta rays get?
The lifespan of a manta ray is believed to be between 50 and 100 years of age – there is so much we don’t know about them yet!
We do hope our efforts in tracking and monitoring the manta rays around Hawaii over time will help uncover more of their mysteries,
One example is Lefty, an adult manta that has been spotted in Hawaii for a duration of over 45 years.

How Can You Tell Individual Manta Rays Apart?
Are manta rays social creatures?
Manta rays seem to be solitary creatures, coming together only to feed and mate.
When they do get together, magic happens: manta rays developed intricate techniques both for mating and feeding.
Are manta rays dangerous?
Manta rays are generally thought of as harmless creatures. They do not have barbs, a stinger, or teeth.
Flight is their only defense mechanism; their maneuverability and speed make them hard to prey on. Thanks to their large pectoral fins, they are capable of bursts of high speed, which they use to escape predators.

manta ray reproduction
Are manta rays fish or mammals?
For the longest time, the world thought that manta rays were cetaceans – marine mammals. However, manta rays are definitely fish and not mammals.
Mantas do have some characteristics of cetaceans though; they have the largest brain-to-body ratio of all fish, and they are better at problem-solving and communicating than your average fish.
Manta rays are cartilaginous fish in the subclass Elasmobranchii, and close relatives of the shark. Elasmobranchii give birth to live young, but that doesn’t make them mammals; they do produce eggs, and the egg gets fertilized and hatches inside their body.
How do manta rays mate and reproduce?
Manta rays have a very slow reproduction rate; they become sexually mature sometime between the age of 10 and 15, their gestation period takes about 12-13 months, and they give birth to one live pup at a time.
Manta rays have some pretty intricate courtship rituals. While they are generally solitary animals, they do get together to mate.
How are manta ray pups born?
Manta ray females give birth to a live pup. The young are almost exact replicas of the adult form, just smaller.
At birth, the pups appear cigar-shaped with the two pectoral fins rolled around them like a burrito. Reef mantas are about 2 to 3 feet across shortly after birth; pelagic manta pups measure up to 6 feet.
An adult manta female doesn’t care for their pup after birth as they are not paternal animals. This means that after birth, the pups are on their own.
