Rays, just like sharks, are fish with the unique feature of having a cartilaginous skeleton. They are part of the elasmobranchs, a subclass of cartilaginous fish grouped within the class Chondrichthyes.
Classification
Rays are classified into three main orders, namely:
  1.  the order Myliobatiformes12 species
  2. Atlantic white-spotted eagle ray (Aetobatus narinari)

Description
Rays are characterized by a flattened body that extends on each side into large pectoral fins called “wings.” The body and pectoral fins form a single continuous structure. Unlike sharks, the gill slits are located on the ventral side of the ray and number five pairs for most species.

Rays display colors and patterns that allow them to blend easily with their surroundings.
Geographic range and habitat
Rays are found in all seas and oceans across the globe, at all latitudes and depths: from warm tropical waters to icy polar regions, from shallow coastal waters and coral reefs to deep waters!
While most rays live on or buried in the seafloor, some species are pelagic, such as the manta ray or eagle rays.
Diet
Rays remain camouflaged in their environment to avoid predators and to ambush their prey more effectively.

Rays have a very varied diet. Their menu mainly includes benthic species such as gastropods, shellfish and crustaceans, while the manta ray feeds exclusively on plankton.
Reproduction
In most fish, fertilization is external, occurring after the release of male and female gametes into the seawater. However, rays, like sharks, are an exception to this rule and exhibit internal fertilization.

All rays exhibit internal fertilization, but the development and nourishment of the embryo vary depending on the species. Some rays are oviparous, while others are ovoviviparous.
Did you know ?
  • The manta ray is the largest ray in the world, reaching up to 30 feet in length for the largest individuals!
  • Some ray species have a stinger at the base of the tail, whose sting can be painful and sometimes even lethal.
  • Rays are capable of leaping out of the water !

The common sea fan

The common sea fan
The common sea fan, is a type of soft coral found in the warm, shallow waters of the Caribbean and the western Atlantic ocean. It grows in wide, fan-shaped forms that sway gently with the ocean currents, helping it catch tiny food particles drifting by. Its beautiful purple branches are covered by a thin living tissue that hosts tiny algae, which provide much of the coral's energy through sunlight.
