Seychelles Mahé Flora and Fauna Galleries
Seychelles Mahé Flora and Fauna feature galleries and photos of plants, fungi, invertebrate such as spiders, and vertebrate animals such as reptiles and birds.
Flora on Mahé
The first gallery displays native (endemic and indigenous) species, while the second feature invasive and introduced plant species.
Native (Endemic and Indigenous) Plants on Mahé
Seychelles Pitcher Plants: These threatened species have modified leaves called pitfall traps with deep cavities filled with digestive fluid. Furthermore, when insects fall into the pitcher, the trap shuts, and prey gets digested. In this way, the plant receives the nutrients it cannot obtain from poor soils at Glacis Trois Frères.
There are six endemic palms on Mahé. Three features including Latanier Millepattes, Thief Palm, and vulnerable Millionaires Salad Palm. Specifically, the mature tree of the latter has spathes that develop at right angles to the palm trunk just below the leaves’ crown. Then these spathes eventually split to reveal flower branches.
The Coco De Mer Palm is an endangered Seychelles endemic indigenous to the Mai Valley on Praslin. Although, I photographed the displayed image at the Botanical Gardens on Mahé.
Beach Morning Glory is a native plant that covers some sandy banks on Mahé Islands beaches.
The origin of both the ubiquitous Coconut Palm and the Casuarina trees that fringe some of Mahé beaches and coastal forests is unclear. Both species have replaced much of the original natural vegetation. Established in the eighteen-hundreds plantations grew introduced coconuts. They also occurred naturally on the beaches. Coconut seeds have evolved to spread by water. Therefore, coconuts could be indigenous and naturalised.
In contrast, casuarina trees could be indigenous (Ref 1) or most likely an invasive introduction dating from 1768 (Ref 2 and Ref 3).
Invasive and Introduced Plants on Mahé
Wild Pineapple and Cocoplum are two introduced invasive species (Ref 2 and Ref 3) I found at Glacis La Reserve. And several cocoplums along the Anse Major trail.
Ochna kirkii is a distinctive woody shrub that has a beautiful flowering and fruiting method. It produces yellow flowers which, after pollination, the sepals wither, and calyx closes. Then within the calyx, up to six berry drupelets develop on the swollen red receptacle. The green berries then grow on the receptacle and ripen to a glossy black colour. Finally, eaten by some bird species, thereby distributing the seeds.
Busy Lizzie, a cultivar in Seychelles, may have become naturalised. While walking the Anse Major trail, I photographed a couple of plants on the granite slopes.
The last three photos introduced species: Malay Apple, Breadfruit, and Cannonball Tree.
Fungi on Mahé
Beard Lichen at Glacis La Reserve
Bearded lichen grows on small leafless shrubs with algae. Both the lichen and algae have a symbiotic relationship. Because the algae photosynthesise food for the lichen, and the lichen stops the algae from drying out.
Fauna on Mahé
A single invertebrate gallery displays images of a Snail, Spider, Crabs, and Stalked Barnacles.
Snail, Spider, Crabs and Barnacles on Mahé
The Giant African Land Snail (Achatina sp.) I have identified it as species fulica, but it could be Immaculata.
A female Palm Spider, part of the golden orb family, often seen amongst electrical power cables and palm trees. Both species include images showing dorsal and ventral views.
Crabs and Barnacles
Giant Mangrove Crabs inhabit freshwater swampy stream and estuaries. I photographed them at or near their burrows in Aux Pins Mangrove swamp.
In contrast, I photographed two crab species and goose barnacles on Anse Bazarca beach. Specifically, a Swift-footed Crab on the rocks near the sea, a juvenile Horned Ghost Crab on the sand near its burrow, and Goose Barnacle on debris washed up on the sand.
The first vertebrate gallery features reptiles and mammals, while the second and third display birds and their behaviours.
Reptiles and Mammals on Mahé
Endemic Seychelles fruit bats photographed at Mont Fleuri Botanical Gardens; it is the only endemic mammal on Mahé. Sheath-tailed bats on Silhouette Island is the only other endemic mammal in Seychelles. However, Seychelles has four or five introduced mammals. These include common tenrec and three pests, the Norway (Brown) Rat, Ship (Black) Rat, and a House Mouse.
Birds on Mahé
Native and Seabirds
On the central Seychelles islands, only 38 bird species breeds, including nine introduced. Nineteen native landbirds; the rest are seabirds (Ref 4). The gallery displays a collection of Seychelles bird portraits from my bird web pages.
Native Birds: Grey Heron.
Endemics Birds: Seychelles Bulbul and Striated Heron subspecies (degens).
Introduced Landbirds: Madagascar Turtle Dove, Red Fody and Zebra Dove (Barred Ground Dove).
At least 16 species of wader (shorebirds) are annual visitors to central Seychelles islands, but none breed (Ref 4). Featured birds photographed on Anse Bazarca are Grey Plover, Crab-plover, Whimbrel, Terek Sandpiper, Ruddy Turnstone and Sanderling. Except for the crab plover, which breeds in the Red Sea and the Persian Gulf, the other waders breed in the far north of Europe and Siberia. They migrate south to the East African Coast and Seychelles to avoid the harsh northern winter months arriving as early as October and leaving as late as May. I also photographed a common or roseate tern fishing close to the beach.
Migrant Shorebirds: Sanderling, Whimbrel, Ruddy Turnstone, Crab-plover, Terek Sandpiper, and Grey Plover.
Bird Behaviour on Mahé
Striated Heron fishing, Roseate Tern also fishing and Crab Plover, an adult and immature resting on the shoreline at Anse Bazarca.

Animal Classification and Photo Galleries
The figure shows a classification diagram in time-ordered evolutionary history to illustrate the arrangement of fauna in the photo galleries:
Invertebrates contain a single gallery with:
(1) Gastropoda (Snails) placed in Mollusca (Molluscs),
(2) and Arachnida (Spiders) and Malacostraca (Crabs and Stalked Barnacles), which belong to Arthropoda (Arthropods).
Vertebrates comprise two galleries:
(1) Reptilia (Reptiles) and Mammalia (Mammals),
(2) And Aves (Birds) with portrait and behaviour galleries, both placed in Chordata (Vertebrata).
