The squid eggs have been with us now for almost three weeks and have recently gone through some major growth spurts. Individual squid are surrounded by an egg membrane and then further enclosed in long pods by the hundreds . The little squidlets are now a whopping millimeter long and have defined eyes, arms, mantles, pigment spots, and a shrinking yolk sac as somewhat visible in the following photos/videos taken using the aquarium microscope. These opalescent squid generally grow to no larger than 20 centimeters during their short 4-9 month lifespan. We can expect that they will be approximately half a foot long by the end of summer.
On a larger note, the seven grooved tanner crabs that are now residing with us live quite differently. They are a deep-dwelling crab brought to us by the always-awesome Sena II crew. Hauled up from 300 fathoms, or 1800 feet deep, their bulging broad abdomens indicate that all of these bright orange beauties are pregnant females. In The Deadliest Catch television show the crabbers are catching a very similar looking but much larger crab, the Alaskan king crab.
Founder of the Ucluelet Aquarium Society and very experienced commercial diver Phillip Bruecker is in town so the aquarium has been getting lots of new critters, including a stubby rose anemone. This anemone closely resembles the red fish-eating anemone, but has much shorter tentacles and settles by burrowing into fine substrate and expanding its base to anchor itself. A bright-striped painted greenling has also found its way to our waters along with a couple of yellowtail rockfish, lingcod, and a temporary visit from a ratfish. The female ratfish has a completely cartilaginous skeleton and is related to skates and shark as seen in their similarly boneless bodies.

See you soon- we’ll get you hooked!
