The Tyuleniy Archipelago is a significant group of islands located in the Caspian Sea.

These islands sit in the north-eastern part of the sea. They are positioned off the Mangyshlak Bay. This area is west of the Mangyshlak Peninsula. The islands also lie northwest of the Tupkaragan Peninsula. They are situated north of Bautino. Administratively, this archipelago belongs to the Mangystau Region of Kazakhstan. The name "Tyuleniy" translates to "seal" in English. This name honors the Caspian seal, which is currently an endangered species.

Human understanding of these islands began with careful scientific study. Fedor Ivanovich Soimonov led the Caspian Expedition in 1719. His team studied the Caspian Sea from 1719 until 1727. This work allowed them to map the archipelago accurately for the first time. Early maps did not show all the islands with detail. For example, a map from 1721 by Van Verden only named one island.

That specific island was Kulaly. Through the work of Soimonov, the geography of the group became clear.

The archipelago consists of several distinct islands with unique features. Kulaly Island, or Kulaly-Aral, is the westernmost and longest island. Its shape is irregular because it contains many inlets and headlands. Kulaly is the only island in the group inhabited by humans. It hosts a meteorological station and a lighthouse. It also contains a Kazakh border guard post. The terrain on Kulaly varies between arid land and waterlogged areas covered in reeds. This island serves as a vital hub for the group.

Morskoy Island is the second largest island in the archipelago. It is notable for having the largest area of the islands. Most of the land on Morskoy consists of wetland. South of Morskoy lies Rybachy Island, which was formerly known as Ostrov Svyatoy. This island is characterized by a long and narrow shape. To the northeast of Rybachy, you will find Podgornyy Island. Each island contributes to the complex layout of the archipelago.

Novyy Island is the easternmost island in the group. It sits in the space between Podgornyy and the mainland. The physical shape of Novyy Island has changed significantly over time. It used to have an irregular shape. However, recent pictures indicate the island has eroded heavily. This erosion has been noted since about 2009. Such changes show how the sea constantly reshapes the islands' boundaries.

The environment across the archipelago is largely desert-like and sandy. There is very little grass growing on the islands. However, the leeward side of Kulaly features many reeds. Other islands in the group are much lower and remain waterlogged. These wetlands provide essential habitats for various species. In past centuries, many Caspian seals visited these shores. This history of animal presence helped define the identity of the archipelago.

Ecologically, the Tyuleniy Archipelago is a vital sanctuary. It has been declared a National Protected Zone, also known as a State Reservation. It is also recognized as an Important Bird Area. During their nesting period, large concentrations of birds arrive here. You can find many seagulls and various wetland birds. These include coots, wild ducks, swans, egrets, and waders. The archipelago also serves as an important breeding ground for the Sandwich tern, known scientifically as Thalasseus sandvicensis. The protection of this area is essential for these bird populations.
