tropical fish of East africa
East Africa Diving
The Indian Ocean is filled with unspoilt reefs and abundant sea-life. Divers from all over the world visit Zanzibar year after year to enjoy the tropical water and vibrantly colourful world underwater world of this East African island. Dive sites around Zanzibar have abundant tropical fish and creatures that have never disappointed those that come to dive or snorkel East Africa.
There are many to mention, but here are a few:
Green sea turtle
Green Sea turtles are beautiful creatures and classified as endangered, but can still be seen around Zanzibar. Turtles are herbivores and can grow up to 5 feet (1.5 meters) and weigh more than 700 pounds (300 kgs), making them one of the largest sea turtles and herbivores. They enjoy a sunbathe on the beach every now and then and also lay their eggs on the beach in nests
In the Eastern Pacific, a group of green turtles that have darker shells are called black turtles by the local community.
You might think their name is from the colour of their shell, but in fact it comes from the greenish colour of their cartilage and fat.
Divers can spot seahorses mainly in shallow tropical and temperate water where they can be found in sheltered areas such as seagrass beds and coral reefs. These delicate beings are on the endangered list too and are often dried and sold as delicacies in the East.
Fun fact: the males carry unborn young and seahorses mate for life.
Sea stars (also called Seafish although they are not fish)
Sea stars are invertebrates. They can get up to 11 pounds (5 kgs!) and sizes average between 4.7 and 9.4 inches (12 cm to just under 24 cm) Some live up to an age of 35 years.
They search for food using their light-sensitive eyespots on the tips of the arms. They mostly feed on mollusks such as clams, oysters, and snails and eat by attaching to the prey before extending their stomach out through the mouth. Enzymes do the rest of the work, breaking the food down to digest.
Sea stars have a wide variety of habit and can be found on rocks, in tidal pools, grassy shores, on the beach and around coral reefs.
Found on their own or in schools around coral heads and rocky outcrops, they feed on crustaceans and small fish. They are pretty wide spread and can be found in moderate depths with some living much deeper (range of anything between 5-30 m.
They hunt at night (nocturnal predators) and eat mainly fish, but will eat crustaceans, gastropods and cephalopods.Their average size is around 30 cm.
Lionfish is also called zebrafish, firefish, turkeyfish, tastyfish or butterfly-cod, recognised and characterized by the red, white, creamy, or black bands stripes and fan-like pectoral fins. They are venomous spiky fin rays.
Lionfish are active hunters. They sometimes retreat to crevices between rocks and corals, but can be seen moving about both alone or in small groups. They ambush their prey by using their outstretched, fan-like pectoral fins and slowly “corner” them.
An adult lionfish can grow as large as 18 inches, while juveniles may be as small as 1 inch or less.
Because lionfish are venomous, not poisonous, there is no harm in eating the lionfish meat. Once you dispose of the spines, there is no risk.
