Fun Blue-spotted Ribbontail Ray Facts For Kids
Gallery
The blue-spotted ribbontail ray (Taeniura lymma), also known as the lagoon ray, is a species of the endless ocean with distinctive blue spots and a remarkable venomous tail. They use the tail to attack smaller fishes and crabs.
Few groups have been seen in the tropical marine aquarium habitat near Ningaloo Reef situated in Western Australia extending up to the coral reefs of Queensland. These fishes can be seen completely buried while luring prey or while migrating.
During the breeding period, in order to attract a female to mate, the male is observed to follow the female with its nose near the female's cloaca.
A cloaca is a rear digestive tract cavity in the female body responsible for genital discharge. If the female releases a certain chemical, it indicates that the female is interested in mating, or else they tend to swim away.
The two spines present are large and medium-sized respectively. The body is yellow-greenish to yellow-brownish with yellow eyes and is capable to change the pupil's size and look behind as well.

The eggs remain within the female body until it is time to hatch. During the early spring, these fishes are seen near the Tanzanian coast.
The mating includes activities related to the disc. Blue-spotted ray adults nibble or bite the disc where the females are fertilized internally by the males using the claspers.
The breeding period occurs generally during the time between spring and summer. The gestation continues for 4-12 months, producing four to seven young per litter near the coral reefs.
The young have a length of around 4.72-5.51 in (12-14 cm) and are quick to learn to hide to attack their prey. They resemble their parents in terms of looks and have prominent blue spots throughout the body and the tail starts developing early with the venomous spines within.
