03/08/2024 Création de sujet : Which macroplankton?

Hi,

This macroplankton seems to have a very typical structure. Can anyone help with ID please? The water was full of them at shallow depths of 1m. Sea temperature was 27C. Thank you!

Hi,

Several of these anemones were covering the silt seabed at 4-6m depth. Photo taken at night. I cannot decide on the genus. Any help, also with species is appreciated. Thank you!

31/07/2024 Création de sujet : Which shrimp?

Hello,

I came across several of these very fast-moving shrimps during a night snorkel. Very hard to get a decent photo. Splash zone, on vertical rock faces. The orange colour and blue specks were conspicuous. Any help is appreciated. Thank you!

This ribbon-like animal was seen at night, swimming in undulations at the surface. Animal was maybe 40–50cm. Any idea what it could be? Sorry about picture quality – it is a still from a low-res footage. Thanks.

HI,

I found this sponge in a dark crevice close to the surface. It does not quite look like Phorbas tenacior. Any ideas please?

Hello,

I am assuming this is Spicara maena, but just want to confirm with the experts that it is not Spicara smaris. Thank you for your help!

I found these gelatinous forms under a pebble in shallow water (1m). Are they tunicates? They were 3-5mm across and on the underside of the stone. Expert help much appreciated!

07/09/2022 Création de sujet : Aiptasia mutabilis?

Hi,

I saw this very small anemone under a pebble in shallow water. Could it be a young Aiptaisia mutabilis or another species please? I assume that the purple organism is Cystodytes dellachiajei.

Thank you very much for your help. I have learnt so much through this site!

05/09/2022 Création de sujet : Porifera or ...?

Hi,

I found these two species encrusting the underside of a pebble in very shallow water. The pink one was ca 12cm wide and the white one was ca 6cm. What animal groups are they? I can't see whether they are porifera or bryozoan, or maybe neither. Would be grateful for expert help. Thank you very much.

Hi,

I am familiar with Thylacodes arenaria, but today I found these ones, with pale body and living in a colony. They were about 8mm diameter. Can anyone identify them please?

Thank you very much,
