Amblyeleotris

Amblyeleotris is a genus of fish in the family Gobiidae found throughout the Indo-Pacific region. This is the largest genus of the shrimp gobies or prawn gobies, so-called because of their symbiotic relationship with certain alpheid shrimps. The shrimp excavates and maintains a burrow used by both animals while the goby, which has far superior eyesight, acts as a lookout for predators. The shrimp maintains almost constant contact with the fish with an antenna. Fossil Amblyeleotris otoliths have been found together with alpheid shrimp remnants from as early as late early Miocene (Burdigalian) suggesting a possible mutualistic association since then.

Time the record covers

At most 18 million years on record.

Every occurrence read is dated to somewhere between 23.04 Mya and 5.333 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

4 occurrences of Amblyeleotris on record, most of them in the Miocene. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

4 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 2 sites for Amblyeleotris, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Entered from

1 reference

Each of the 4 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
